5. The Neuron Nerve Cells - Billions in the nervous system
- Carry chemical “messages”

6. Receives messages from other neurons

7. Carries messages to other neurons

8. Fat and protein coating on the axon that aids transmission

9. Where messages are sent to other neurons.

10. Resting Potential

11. Action Potential All-or-None
- Message is either transmitted or it is not

12. Action Potential In Action

13. The Synapse Synapse Neurotransmitters - Specialized chemical messages
- Space between terminal button and dendrite
Neurotransmitters
- Specialized chemical messages
The Synapse

14. Transmitter-Receptor Fit
Three Sites:
- Two on the terminal buttons
-- Release Sites
-- Reuptake Sites
- One on the dendrites
-- Receptor Sites
Neurotransmitters are specialized.
Different neurotransmitters have specific sites.

15. Drugs at the Synapse

16. Neurotransmitters’ Specialized Roles
Many varying effects on behavior/thought.
Neurotransmitters either inhibit or excite the next neuron.
Inhibitory Messages – Makes firing less likely.
Excitatory Messages – Makes firing more likely.
Neurotransmitters are not limited to one role all the time.
Are usually one or the other most of the time.
