Document Summary

Blindsight seeing is not connected fully to the eyesight. The brain helps us predict where we may see things. Stroke patients usually exhibit blindsight their body may be inhibited but their brain is aware of their entire body. Concentration gradient motivation to travel to a location from high to low concentration. Electrical gradient describing motivation of charged particle to travel to a location to create a charge closer to 0, or electrical equilibrium. *positive charged will travel towards neg charged area to create area closer to neutral charge. A strong desire to move in/out is going to cause the change to happen quickly. ***na+ will quickly enter the neuron, causing a change in overall charge, which causes the action potential! If the electrical potential of the neuron reaches -55mv by allowing na+ to enter, the axon hillock will decide to fire off an action potential.
