- 1. Neuroscience and Behavior
2. Neurons Neurons are similar to other cells in the body
because: Neurons are surrounded by a cell membrane.Neurons have a
nucleus that contains genes.Neurons contain cytoplasm, mitochondria
and other organelles.Neurons carry out basic cellular processes
such as protein synthesis and energy production.However, neurons
differ from other cells in the body because: Neurons have
specialized extensions calleddendrites and axons. Dendrites bring
information to the cell body and axons take information away from
the cell body. Neuronscommunicatewith each other through an
electrochemical process.Neurons contain some specialized structures
(for example, synapses) and chemicals (for example,
neurotransmitters). 3. Neurons Take-away door prize:Build your own
neuron! 4. Electrical Signaling
-
- myelin and nodes of Ranvier
-
- Hand holding (hands, ankles, shoulders)
5. Synaptic cleft (Synapse)
-
- 100+ trillion synapses!!!
6. Electro-Chemical Signaling
7. Neurotransmitters Many different types (60+):amino acids,
peptides, monoamines 8. Neurotransmitters
- DVD clips( Moving images &/or Discovery)
- Most drugs have their effects by enhancing or interfering with
synaptic transmission
-
- agonist (e.g., cocaine, which blocks reuptake of dopamine)
-
- antagonist (e.g., caffeine antagonist of adenosine
receptor.Adenosine has a sedating effect)
9. Organization of Nervous System 10. Central Nervous System
11. Autonomic Nervous System
12. Endocrine system The glands of the endocrine system and the
hormones they release influence almost every cell, organ, and
function of our bodies.The endocrine system is instrumental in
regulating mood, growth and development, tissue function, and
metabolism, as well as sexual function and reproductive processes.
13. Nervous + Endocrine The hypothalamus, a collection of
specialized cells that is located in the lower central part of the
brain, is the primary link between the endocrine and nervous
systems.Nerve cells in the hypothalamus control the pituitary gland
by producing chemicals that either stimulate or suppress hormone
secretions from the pituitary. 14. 3.4 Exploring the Brain Major
Divisions
-
- Pons, medulla, and reticular formation (arousal, sleep, cv, rr,
relay for sensory info)
-
- cerebellum (coordination of movement)
15. 3.4 Exploring the BrainMajor Divisions
-
- Tegmentum (movement, pleasure, motivation)
16. 3.4 Exploring the BrainMajor Divisions
-
- thalamus ( most neural input to the cortex is received from the
thalamus)
-
- Hypothalamus (oversees wide range:temp, hunger, thirst, sexual
behavior)
-
- pituitary gland (connects brain to other endocrine glands)
17. 3.4 Exploring the BrainMajor Divisions
- Limbic system(The four Fs:Fighting, Fleeing, Feeding, and
Mating)
18. 3.4 Exploring the BrainMajor Divisions
-
- plasticity(Discovery DVD)
19. Brain http://www.pbs.org/wnet/brain/3d/index.html PSYCHOLOGY
20. 3.6Investigating the Brain
- Studying the damaged brain
-
- emotional functions of the frontal lobes
21. 3.6Investigating the Brain
- Distinct roles of left and right hemispheres
22. 3.6Listening to the Brain
- Electroencephalogram (EEG)
- Brain patterns while sleeping and awake
23. 3.6Brain Imaging
-
- positron emission tomography (PET)
-
- functional magnetic resonance imaging (fMRI)
-
-
- provides a picture of the level of activation in each brain
area
