Lecture 1 Office hours: Friday 2:00 3:00 BS III 2120 Beginning today Synapses stimulate cells in out brain Synapse is where the processing of information goes on Inside of the axon is cytoplasm/exoplasm you dissolved salts in water it becomes a better conductor Signal fades away gradually This problem arises because axons are and thin The axon can be as much as a meter long It resists the flow of electricity down it A capacitor is an electrical device that can store
