Document Summary
Mainly focus on structure : localization vs distributive processing ! Is a function localized or distributive across the brain (in one place or all over) : neuron ! Soma > dendrites receives information from other cells (signal from receptor sites) > axon > These neurons can be very short but also very long (some you can see with a naked eye: synapse ! Causes some effect in the next neuron ! Whether a cell receives a signal or not it has some activity however its a matter of whether or. A very strong signal has a strong action potential ! A very weak signal has a strong action potential ! Spontaneous ap: some # of activity in a given amount of time ! Excitatory ap: more amount of activity in a given amount of time ! Inhibitory ap: little amount of activity in a given amount of time : brain imaging techniques!
