We're made up of
1. sensations
2. feelings
- when a neuron fires a wave of chemical charges through the axon
-
action potential
-
when the threshold of excitation is reached and the axon gates opens, casuing positive ions to flow inside
- depolarization
-
when there is an excess of negative ions inside and positive outside
- polarization
