,cerebral cortex function - Correct answer-Is the center for humans highest
functions governing thought, memory, reasoning, sensation and voluntary
movement.
Depolarization - Correct answer-Initial (excitatory) - when sodium is rushing into
the cell causing the interior to become more positive.
Repolarization - Correct answer-Restoration (inhibitory)- caused by reentry of
potassium into the cell while sodium exits the cell.
Dopamine (DA) - Correct answer-A monoamine transmitter found in the
midbrain—especially the substantia nigra—and basal forebrain
** Ventral Tegmental Area- Nucleus accumbens.
Norepinephrine (NE) - Correct answer-a monoamine neurotransmitter in locus of
ceruleus
-involved in alertness and vigilance and control of REM sleep
in mood, anxiety and concentration d/o
Epinephrine - Correct answer-Monoamine Neurotransmitter secreted by the
adrenal medulla in response to stress. Also known as adrenaline.
