“Re-wiring” Brain Functioning for Academic Talent Development:
Applying Non-Invasive Neural Research to Classroom Practice as a Means to Develop
Student Capacity to Learn.
Harold G. Begay, Ph.D.
Recent research in both laboratory and human brain morphology suggests that the way we teach
can alter the anatomical properties of the neural architecture associated with cognitive functioning and
ability. With the advent of multidimensional, non-invasive, and non-hazardous imaging technologies,
neuroscientists have been enabled to more thoroughly investigate the significance of the environment to
neural connectivity and associated cognitive functioning. For the educational sector, Diamond (2003),
one of the leading neuroscientist for the past quarter century, has been emphatic that these findings can
have a powerful impact on how learning may be optimized:
The message is clear: Although the brain possesses a relatively constant macrostructural
organization, the ever-changing cerebral cortex, with its complex microarchitecture of unknown
potential, is powerfully shaped by experiences before birth, during youth and, in fact, throughout
life. It is essential to note that enrichment effects on the brain have consequences on behavior.
Parents, educators, policy makers, and individuals can all benefit from
such knowledge. (para. Abstract)
In an extensive review of recent neural studies, Jensen (2002) noted that one of the most
important research developments in non-pathological neuroplasia is that classroom teaching changes the
neuronal brain architecture and its cognitive functioning correlates. Fletcher et al. (2000) further
summarizes the more significant findings in educational cognitive neurology that supports the malleability
of our brain as we interface with the environment. Cumulative empirical evidence from neural research
continues to document that each day in our schools teachers using certain instructional practices can
stimulate or inhibit neurological growth in brain regions that underlie cognitive functioning (Jensen, 2001).
Sylwester (1995), another leading advocate for linking neuroscience to classroom practice, challenges
educators today to become more creative in applying studies from the neural research community to
strengthen classroom practice:
…research involving an enriched environment is important for educators, …. and the enrichment
research indicates that the basic networks regulating a brain’s interactions with its environment
can maintain their plasticity and vigor throughout life if stimulated to do so. Because neurons
thrive only in an environment that stimulates them to receive, store, and transmit
information, the challenge to educators is simple: define, create, and maintain
an emotionally and intellectually stimulating school environment and curriculum (p. 129-130).
While discovery of brain region network association or disassociation with specific behavior and
cognition has drawn critical interest, the ability of the human brain to respond to one’s experiences and
organize or re-organize itself to accommodate and process multiple sensory inputs to functionality or
enhanced functionality is of crucial significance to the educational community, especially in changing and
strengthening classroom teaching and learning (Bransford et al., 2002). Diamond, Scheibel, Murphy,
and Harvey (1985) and Jacobs, Schall, and Scheibel (1993) from their studies

The implications are that classroom teaching and learning experiences can be redesigned and
calibrated so as to neurologically enhance the intellectual and academic capacity of humans to learn at a
much more complex and higher level. Diamond (Diamond, 2003), captioned some recent advances in
neuroplasia as follows:
…these studies and what few human studies have been done, suggest that there are
measurable benefits to enriching an individual's environment in whatever terms that
individual perceives his immediate environment as enriched. At the very least, this work
indicates that there are many opportunities for enhancing brain activity and behavior at
all ages, and that they can have pronounced effects throughout the life span. (para. 14)
From cross-cultural research, the significance of the environment to enhance human learning and
performance in this regard corroborates the importance of providing appropriate “cultural amplifiers” and
“cultural transmitters” to enhancing intellectual and academic ability (Ogbu, 2002). Micro-environmental
stimulation is thus crucial not only to prenatal and early childhood development, but to lifetime brain
maturation, optimizing neural functioning and productivity (Begley, 2002; Diamond, 1999). The findings
that micro-environmental stimulation is crucial to brain activation and maturation adds a powerful
dimension to enhancing and strengthening classroom instruction, the nexus where teachers engage
directly with children and student learning on a daily basis.
All schools could benefit from use of certain enriched teaching modules to stimulate and
strengthen specific neural regions that have been found to correlate highly with cognitive functioning and
enhancement.

Our Brain, A Dynamic, Evolutionary Organ: Implications for Enhancing Classroom Practice and
Academic Development.
Continuing scientific research developments in neurology indicate that our brain is a dynamic,
evolutionary organ, capable of responding to experiences and changes in the form of morphological
alterations in the most dramatic forms (Begley, 2002: Bransford, Brown, & Cocking, 2002). The
generative and regenerative neuronal cell morphology has been referred to as neural plasticity or
neuronal transdifferentiation, which is essentially stem cell differentiation or unspecialized cells taking on
specialized neural physiological attributes and functions (National Institutes of Health, 2004; National
Institutes of Health, 2003a; National Institutes of Health, 2003b; Gaurav, K.V., 2002).
Quartz and Sejnowski (1997) from their extensive work in neurology, cognition, and direct
brain-environmental interface, concluded that there is a far stronger dynamics between human
performance, our neurological structures, and the environment than has been previously documented:
…learning is a dynamic interaction between a changing, structured environment and neural
mechanisms. The neural machinery is extensively shaped by activity stemming from the
environment, while its intrinsic properties also constrain this modulation and play an indispensable
role in shaping the resulting structures. … as a consequence, this makes the relation between
environmental changes---whether natural or cultural---and brain structure a direct one (para. 12).
For underachieving school and students, these recent findings on the importance of experience
to neuronal and cognitive optimization are particularly important as these findings reaffirm
underachievement issues as real challenges for the schools and the instructional staff, not so much that
of the learners, their families and background. These developments in brain science offer substantial
support to instructional practices that engage active teaching and learning where exemplary teachers in
particular stimulate and enhance the distributive functional powers [To access the full article, please

more by experience and the environment in the form of evolutionary changes than simply
maturational innate changes in specialized neural circuitry:
Neural constructivism suggests that the evolutionary emergence of neocortex in mammals is a
progression toward more flexible representational structures, in contrast to the popular view of
cortical evolution as an increase in innate, specialized circuits. Human cortical postnatal development
is also more extensive and protracted than generally supposed, suggesting that cortex has evolved
so as to maximize the capacity of environmental structure to shape its structure and function through
constructive learning. (Abstract p.)
Based on these recent discoveries in cognitive neuroscience, some educators have begun
identifying effective, powerful teaching strategies to enhance student achievement and other desirable
schooling outcomes (Begay, 2005). More and more school districts are beginning to engage
well-renowned experts in neuroscience to apply the recent findings from neuroplasia to classroom
practice as documented by the Bransford et al., (2002) that: 1.) Learning actually changes the physical
structure of the brain (Bransford et al., 2002, p. 115); 2.) These structural changes alters the functional
organization of the brain; in other words, learning organizes and reorganizes the brain (Bransford et al.,
2002, p. 115); 3.) Different parts of the brain may be ready to learn at different times (Bransford et al.,
2002, p. 115); 4.) [To access the full article, please contact the author [email protected] ]
The quality of information to which one is exposed and the amount of information one acquires is
reflected throughout one’s life in the structure of the brain (Bransford et al., 2002, p. 118); 5.) The brain
is a dynamic organ, shaped to a great extent by experience – by what a living being does, and has done
(Browning et al., 2002, p. 126); 6.) Environmental stimulation, nurturing, can and will greatly enhance
learning to a far greater degree than has been documented in behavioral and cognitive research; 7.)
Long-term potentiation, or exponential encoding, similar to creating a path in walking/running, provides for
ease and efficiency in information / knowledge acquisition. Information is learned multiple times each
time it is practiced (Bransford et al., 2002).
These findings in neuroscience should serve as an impetus in professional practice to build new
and/or different neurological pathways principally through carefully calibrated enriched instructional
teaching strategies to improve student academic performance. It is in the interest of pupil and student
intellectual enhancement that schools invest in classroom teachers to apply scientific findings from neural
research in the design of enriched instructional teaching

learning, phonological and orthographic processing for reading and problem solving, and
mathematical reasoning and textual processing has been extensively documented (Demb, et al., 1995;
Gabrieli, Brewer, Desmond, & Glover, 1997; Illes, et al., 1999; Poldrack, & Gabrieli, 1997; Prabhakaran,
Rypma, & Gabrieli, 2001.; Prabhakaran, et al., 1997;. Seger, Desmond, Glover, & Gabrieli, 2000; Seger,
et al., 2000; Temple, et al., 2001; Thompson-Schill, Aguirre, D'Esposito, & Farah, 1999), the design or
identification of instructional strategies that will strengthen those neurological circuitry critical to higher
and advanced complex cognitive functioning continues to lag. Challenges remain for
educational researchers to now identify or design instructional practices that will lead to enhanced
complex cognitive functioning via neurological morphology.
The respective National Council for Teachers of Mathematics (NCTM, 2000), English (National Council
for Teachers of English, 2000), and Science (National Science Teachers Association, 2000), The College
Board (2000), and Cohen & Lotan (1997), although not engaged in neuroscience, offer the most
defensible instructional strategies wherein instructional programs use higher order critical thinking and
communication to cultivate deeper subject matter comprehension to achieve complex cognitive
functioning via neurological changes and neuronal functioning. Through use of these, and similar,
enhanced instructional practices emphasizing developing higher level cognitive processing skills, all
students should gain

This is a way to more accurately determine and develop student’s intellectual capacities, abilities, and
potential, particularly language-minority students and school children.
Bilingualism and Giftedness.
While the challenges are great, advanced technology continues to improve making possible
anatomical neural mapping, image and morphometric analysis and the like as researchers explore our
brains at work, examining in vivo neural arborization, spining and bouton plasticity. Even with the
limited research activities with human subjects, there are strong promising signs that curricular programs
and instructional practices can be redesigned toward changing targeted cortical regions found to be
crucial to or associated with core academic growth and development. There continues to be increasing
interest in the dynamics of bilateral hemispheric progression, cellular signaling, and neuronal network
recruitment for lost or debilitating cognitive functions, as well
[To access the full article, please contact the author [email protected] ]
neural network regions of interest for educators are the left frontal brain regions, activity in the left
temporo-parietal cortex, extrastriate cortex activity, especially in the occipito-parietal regions, which are
the neural regions associated with phonological and orthographic processing, the foundations for reading
(Temple et al., 2001). Other neural estates that have drawn critical interest are the bilateral frontal
regions, the frontal cortex, and temporal cortex. These neural regions are associated with
problem-solving tasks, mathematical reasoning, and text processing, and these cortical areas have been
documented to mediate and underlie much of the various known reasoning processes (Prabhakaran,
Rypma, & Gabrieli, 2001; Prabhakaran, Smith, Desmond, Glover, & Gabrieli, 1997). Another critical
neural region of interest is the right middle and superior frontal gyri, left middle frontal gyrus, and bilateral
cerebellum, which are associated with creativity, converging distant association and problem solving
(Seger, Desmond, Glover, & Gabrieli, 2000). [To access the full article, please contact the author
with activity in the prefrontal lobe associated with executive functioning when gifted or bilingual subjects
are engaged in various cognitive and bilingual language tasks (O’Boyle, Benbow, & Alexander, 1995;
Fingelkurts & Fingelkurts, 2003; http://www.bm-science.com/team/chapt2.pdf ; Illes et al., 1999; Singh &
O’Boyle, 2004). The role of strong emotions and categories of memory has also drawn much interest
with profound giftedness. Gifted subjects are able to more efficiently process data sensory input using
these neural regions – they make better use of their brains regions simultaneously.
There is now strong interest to develop or further enhance these specific cortical regions with certain
external cueing, specifically enriched extended teaching practices and activities, which includes the arts,
music, and physical movement education (Begay, 2007; Begay, 2006). Using these studies in brain
research, related cognitive work, the teaching dynamics, and carefully calibrated educational
experiences, one can expect major dramatic positive changes in the academic performances of school
children, changes which can only enable and enhance students’ capacity for immediate and long-term,
life long learning.
Beyond neurocytology, experience and the environment are thus demonstrated as essential and critical
to neurocognitive functioning either to maturation or atrophic diminution. Cognitive scientists have now
established empirical evidence for the seminal neural theories originally advanced by Cajal and Golgi in
the late 1800’s and early 1900’s that the human brain is capable of continuous maturation and
reorganization given specific environmental stimulation and engagement (Bentivoglio, 1998; Nobel
Foundation, 2004).
For Native American students, if we are to see significant improvement in learner outcomes, a critical
mass of teacher-leaders must be trained as master teachers well versed in this form of scientifically
based teaching and learning strategies, and further, embedded in traditional indigenous epistemology
and ontology in human growth and development.
Indigenous Native American Epistemology as the Fundamental Framework for Sustained Effective
Professional Work in the Native Communities.
With Native schools, it is essential that teachers first cultivate their connections with indigenous
Native American epistemology and ontology in human growth as the fundamental framework for
sustained effective professional work in the Native communities. It is important that educators, parents,
policy makers address this fatal disconnection in education that has discredited American Indian
traditional philosophy of teaching and learning for too long (Jester, 2002). Professional development in
schools must recognize that the traditional Native philosophies of teaching and learning represents
another significant cultural educational genre in the global sphere of human learning, and that this cultural
framework is a source of human strength, not a weakness of the human mind.
Romero (2002) enunciates most distinctly the importance of reclaiming traditional Native
American epistemology to meaningful education and adult productivity for Native Peoples. In this spirit
of calling for schools to become more “organic”, it is essential that professional development re-educate
participants to understand that the primacy of indigenous thought and framework [To access the full

Jackson (2004) further describes how these traditional precepts can be infused into all facets of existing
curricular programs, noting, “This is how the SNBH paradigm has a direct connection to the College
philosophy of Sa’ah Naaghai Bik’eh Hozhoon. This paradigm is currently being used at Dine’ College
and can be used as part of a curriculum development process and also as an assessment tool (p. 8.)”
It becomes a cultural imperative that Navajo schools use their Dine’ traditional epistemic philosophy of
teaching and learning as the foundation for their teacher pre-service, in-service and induction programs.
Equally important, educators in Native communities must also acquire an international perspective on
quality effective teaching and learning to help validate and reaffirm that in classroom teaching, the cultural
foundation and framework are very important
[To access the full article, please contact the author [email protected] ]
Japanese teachers also make the subject matter itself “inherently interesting” with little interest in
motivating students in non-mathematical ways typically characteristic of American teachers (Pinker, 1997;
Stigler et al, 1999). This pedagogy supports traditional Native American epistemology in teaching and
learning and serious thought must be given to these non-Western practices and perspectives. As
another example, making mistakes while making new connections in science lessons or math problem
solving, but reviewing, examining and understanding the basis for the mistake is another important
distinction with Japanese teaching and this pedagogy is very compatible with the Dine’ traditional
philosophy of learning.
Knowledge about the subject epistemology and motivation, the teaching process, about the students, the
importance of individual differences as well as the strength of group diversity in knowing, the sanctity of
the lessons, and the teacher’s pedagogic philosophy are thus all important to quality teaching with
Japanese education (Kyoshiyo, 1991; Hatano & Inagaki, 1991; Sasaki, 1997; Takemura & Shimnizu,
993; Shimahara & Sakai, 1995, in Stigler & Hiebert, 1999). These features from highly effective
instructional practices from an international perspective are very compatible with traditional teaching and
healing powers of the Navajo people. This approach to education in schools in Native communities is
very much in line with indigenous traditional philosophy of teaching and learning (Begay, 2007; Begay,
2005; Begay, 2004; Benally, 1987). In this vein, renewed thinking will result in system change or
improvement where [To access the full article, please contact the author [email protected] ]
our schools will be enabled to improve and sustain instructional practices to enhance student
achievement and general life success.
