Document Summary

Psy 2301 d biological foundations of behavior. A neurological disorder marked by sudden recurrent episodes of sensory disturbance, loss of consciousness, or convulsions, associated with abnormal electrical activity in the brain. The diference in electrical charge between two points in a circuit expressed in volts. Positively charged ions; i. e. na+ [sodium] and k+ [potassium] Negatively charged ions; i. e. cl- [chloride] and a- [protein molecules] A graph that records electrical activity through the skill or from the brain and represents graded potentials of many nerves. Movement of ions from an area of higher concentration to an area of lower concentration through random motion. Diference in concentration of a substance among regions of a container that allow the substance to difuse from an area of higher concentration to an area of lower concentration. Diference in charge between two regions that allows a low of current if the two regions are connected.
