How does the mind process all the information it receives?

2. Information Processing Theory

3. Neurons Neurons are the basic unit of the brain.
Any information processed in the mind is processed by neurons.
How can simple neurons generate complex behaviors?

4. Neural computation Three parts:
Dendrite: Receives input from other neurons
Cell Body: Processes input
Axon: Decides and generates output

6. Action Potential
The signal a neuron generates down its axon is called an action potential.
All action potentials are the same magnitude (strength).
We determine how excited a neuron is by its firing rate - how many action potentials per second it generates.

7. Neurotransmitter
Neurons communicate by sending chemical messages called neurotransmitters to other neurons.
These neurotransmitters travel from axon to either the dendrite or the cell body across the synapse.
Where a synapse is depends on what the connection type is
Excitatory: Axon to dendrite
Inhibitory: Axon to cell body
