and more!

3. Biopsychology Some alternate names: Physiological Psychology
Psychobiology
Behavioral Neuroscience, etc.
Controlled manipulation of nervous system of animal subjects
under controlled conditions
Focus on behavior ~

4. Behavior Responses made by organisms to adapt to changing environment
Anything objectively measurable change
also...
cells
molecules
ions ~

5. Regulation of Behavior
Behavior: function of specialized cells
sensory
transduction
neurons
info processing
effectors
muscles
glands ~

6. Neurons Basic functional unit of Nervous System information processing
Transmits
Integrates
Stores
Regulation
behavior
homeostasis ~

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

8. A model of behavior + + + + Effector Sensory Interneuron Cell Motor

9. - + A model of behavior + + + + feedback Positive - excitatory (+)
Negative - inhibitory (-) ~

11. Neurons & Behavior Neural activity  behavior
Alter neural communication
Within & between
Alter behavior
including...
consciousness, emotions, perceptions
