2. Behavior n Any activity that can be objectively recorded n Macro to Micro groups of individuals individual systems cell group cell ion ~

3. Regulation of Behavior n Behavior: function of specialized cells l sensory u transduction l neurons u info processing l effectors u muscles u glands ~

4. Neurons n Basic functional unit of Nervous System l information processing u Transmits u Integrates u Stores l Regulation u behavior u homeostasis ~

5. Shorthand for neuron + = excitation - = inhibition ~ synapse

6. + +++ A model of behavior Sensory Cell Sensory Neuron Motor Neuron Interneuron Effector

7. + + +++ A model of behavior - n feedback l Positive - excitatory (+) l Negative - inhibitory (-) ~

8. REGULATION normal range SYSTEM ACTIVITY Maximum Minimum + ++ -

9. Psychoactive Drugs n Alter behavior l including... consciousness, emotions, perceptions n By altering neural transmission l within l between n Drugs modulate normal function l increase or decrease only l excite or inhibit ~
