1 Unit 2 Biology of Behavior

2 The Neuron

3 Cell Body Nucleus Dendrites

4 Axon Myelin Sheath Nodes of Ranvier Schwann’s Cells Axon Terminals

5 Neural Impulse Resting Potential

6 Neural Impulse Action Potential
Absolute Refractory Period

7 Synapse Synaptic Space/Cleft Synaptic Vesicles Neurotransmitters
Axon Terminal Synaptic Space/Cleft Dendrite Synaptic Vesicles Neurotransmitters

8 Neurotransmitters Types Excitatory Inhibitory Diseases

9 Types of Neurons Afferent Sensory Efferent Motor Interneurons

10 Neurotransmitters Agonists and Antagonists
Agonist: A drug that binds to a receptor of a cell and triggers a response by the cell. An agonist often mimics the action of a naturally occurring substance. An agonist produces an action. It is the opposite of an antagonist which acts against and blocks an action.

11 Neurotransmitters -excitatory
Acetylcholine Norepinephrine Glutamate

12 Neurotransmitters- inhibitory
GABA

13 Neurotransmitters-both
Dopamine Serotonin Endorphin

14 The Nervous Systems

15 Sympathetic Parasympathetic

16 Brain Hindbrain Midbrain Reticular Formation Medulla Pons Cerebellum
Aka. Reticular Activating System

17 Brain Forebrain Thalamus Hypothalamus Amygdala Hippocampus
Cerebral Cortex Cerebrum Corpus Callosum

18 Brain Limbic System

20 Brain Lobes Occipital lobe Temporal lobe Parietal lobe Frontal lobe

21 Brain Cerebral Cortex Right hemisphere Left hemisphere

22 Cerebral Cortex Auditory cortex Motor cortex Visual cortex
Somatosensory cortex

24 Brain Broca’s Area Wernicke’s Area Aphasia Spinal Cord

25 Imaging - structural CT/CAT MRI

26 Imaging - functional EEG PET fMRI TMS

27 Endocrine System Hormones

28 Behavior Genetics Charles Darwin Phineas Gage Nature vs. Nurture
