Studying the Brain
Module 05: The Brain
Studying the Brain: Case Studies
Module 05: The Brain
Case Study
• A research technique in which one person is studied in depth in the hope of revealing universal principles.
• Phineas Gage’s Accident
Studying the Brain: Scanning Techniques
Module 05: The Brain
Computerized Axial Tomography (CT or CAT)
• A series of X-ray photographs taken from different angles and combined by computer into a composite representation of a slice through the body.
• Reveals the brain’s structure
Magnetic Resonance Imaging (MRI)
• A technique that sues magnetic fields and radio waves to produce computer-generated images that distinguish among types of soft tissue;
• this allows us to see structures within the brain.
Electroencephalogram (EEG)
• An amplified recording of the waves of electrical activity that sweep across the brain’s surface;
• these waves, measured by electrodes placed on the scalp, are helpful in evaluating brain function.
Positron Emission Tomography Scan (PET scan)
• A visual display of brain activity. • Injection of a radioactive glucose • Reveals the brain’s functioning
Lower Level Brain Structures
Module 05: The Brain
Lower-Level Brain Structures:
The Brainstem
Module 05: The Brain
Brainstem
• The oldest part and central core of the brain;
• it begins where the spinal cord swells as it enters the skull and
• is responsible for automatic survival functions.
Brainstem
Medulla
• Located at the base of the brainstem, • it controls basic life-supporting
functions like heartbeat and breathing.
• Damage to this area can lead to death.
Medulla
Reticular Formation
• A nerve network in the brainstem that plays an important role in controlling wakefulness and arousal.
• Extending up and down the spinal cord into the brain
• Controls an organism’s level of alertness • Damage to this area can cause a coma.
Lower-Level Brain Structures:
The Thalamus
Module 05: The Brain
Thalamus
• The brain’s sensory switchboard, located on top of the brainstem;
• it directs messages to the sensory receiving areas in the cortex.
• Thalamus is Greek for “inner chamber.”
Thalamus
Lower-Level Brain Structures:
The Cerebellum
Module 05: The Brain
Cerebellum
• The “little brain”, attached to the rear of the brainstem;
• it helps coordinate voluntary movements and balance.
• If damaged, the person could perform basic movements but would lose fine coordination skills.
Cerebellum
Cerebellum
Lower-Level Brain Structures:
The Limbic System
Module 05: The Brain
Limbic System
• A ring of structures at the border of the brainstem and cerebral cortex;
• it helps regulate functions such as memory, fear, aggression, hunger, and thirst, and
• it includes the hypothalamus, hippocampus, and the amygdala.
Hypothalamus
• A neural structure lying below the thalamus;
• it helps regulates the body’s maintenance activities, such as eating, drinking, body temperature, and it linked to emotion.
• Plays a role in emotions, pleasure, and sexual function
Hypothalamus
Hippocampus
• A neural center located in the limbic system that wraps around the back of the thalamus;
• it helps processing new memories for permanent storage.
• Looks something like a seahorse – Hippo is Greek for “horse.”
Hippocampus
Amygdala
• An almond shaped neural cluster in the limbic system that controls emotional responses such as fear and anger.
Amygdala
The Cerebral Cortex
Module 05: The Brain
Cerebral Cortex
• The intricate fabric of interconnected neurons that form the body’s ultimate control and information processing center.
• Covers the brain’s lower level structures • Contains an estimated 30 billion nerve
cells • Divided into four lobes
Corpus Callosum
• The large band of neural fibers that connects the two brain hemispheres and
• allows them to communicate with each other.
• Is sometimes cut to prevent seizures
Corpus Callosum
Longitudinal Fissure
• The long crevice that divides the cerebral cortex into left and right hemispheres.
• This and other fissures in the brain create major divisions in the brain called lobes
Frontal Lobes
• The portion of the cerebral cortex lying just behind the forehead that is involved in planning and judgment;
• it includes the motor cortex.
Parietal Lobes • The portion of the cerebral cortex lying on
the top of the head and toward the rear; • it includes the somatosensory cortex and
general association areas used in processing information.
• Regions available for general processing, including mathematical reasoning
• Designated as the association lobes • Behind the frontal lobes
Occipital Lobe
• The portion of the cerebral cortex lying at the back of the head;
• it includes the primary visual processing areas of the brain.
Temporal Lobes
• The portion of the cerebral cortex lying roughly above the ears;
• it includes the auditory (hearing) areas of the brain.
• Where sound information is processed
Motor Cortex
• A strip of brain tissue at the rear of the frontal lobes that controls voluntary movement.
• Different parts of the cortex control different parts of the body.
• The motor cortex in the left hemisphere controls the right side of the body and visa versa.
Motor Cortex
Motor Cortex
Somatosensory Cortex
• The strip of brain tissue at the front of the parietal lobes that registers and processes body sensations.
• Soma is Greek for “body.”
Somatosensory Cortex
Somatosensory Cortex
Plasticity
• The brain’s ability to change, especially during childhood, by reorganizing after damage or experience.
Differences Between the Brain’s Two Hemispheres
Module 05: The Brain
Hemispheric Differences
• “Left-brained” and “right-brained” debunked
• Brain is divided into two hemispheres but works as a single entity.
• Both sides continually communicate via the corpus callosum, except in those with split brains.
Differences Between the Two Hemispheres:
Language and Spatial Abilities
Module 05: The Brain
The Brain’s Left Hemisphere
• For most people, language functions are in the left hemisphere.
• For a small percentage of people, language functions are in the right hemisphere.
Broca’s Area
• A brain area of the left frontal lobe that directs the muscle movements involve in speech.
• If damaged the person can form the ideas but cannot express them as speech
Wernicke’s Area
• A brain area of the left temporal lobe involved in language comprehension and expression.
• Our ability to understand what is said to us
• Usually in the left temporal lobe
The Brain’s Right Hemisphere
• Houses the brain’s spatial abilities • Our spatial ability allows us to perceive
or organize things in a given space, judge distance, etc.
• Helps in making connections between words

The End
Teacher Information • Types of Files
– This presentation has been saved as a “basic” Powerpoint file. While this file format placed a few limitations on the presentation, it insured the file would be compatible with the many versions of Powerpoint teachers use. To add functionality to the presentation, teachers may want to save the file for their specific version of Powerpoint.
• Animation – Once again, to insure compatibility with all versions of Powerpoint, none
of the slides are animated. To increase student interest, it is suggested teachers animate the slides wherever possible.
• Adding slides to this presentation – Teachers are encouraged to adapt this presentation to their personal
teaching style. To help keep a sense of continuity, blank slides which can be copied and pasted to a specific location in the presentation follow this “Teacher Information” section.
Teacher Information • Domain Coding
– Just as the textbook is organized around the APA National Standards, these Powerpoints are coded to those same standards. Included at the top of almost every slide is a small stripe, color coded to the APA National Standards.
• Scientific Inquiry Domain • Biopsychology Domain • Development and Learning Domain • Social Context Domain • Cognition Domain • Individual Variation Domain • Applications of Psychological Science Domain
• Key Terms and Definitions in Red – To emphasize their importance, all key terms from the text and their
definitions are printed in red. To maintain consistency, the definitions on the Powerpoint slides are identical to those in the textbook.
Teacher Information • Hyperlink Slides - Immediately after the unit title slide, a page (usually
slide #4 or #5) can be found listing all of the module’s subsections. While in slide show mode, clicking on any of these hyperlinks will take the user directly to the beginning of that subsection. This allows teachers quick access to each subsection.
• Continuity slides - Throughout this presentations there are slides, usually of graphics or tables, that build on one another. These are included for three purposes.
• By presenting information in small chunks, students will find it easier to process and remember the concepts.
• By continually changing slides, students will stay interested in the presentation. • To facilitate class discussion and critical thinking. Students should be encouraged to
think about “what might come next” in the series of slides.
