A student notices that at certain times during his studying for final exams, he is more awake and his ability to think at a higher level is happening easier
The nurse knows that this experience may be attributed to which of the following neurological functions?
A)
Release of excitatory neurotransmitters such as glutamate
B)
Release of GABA, an inhibitory neurotransmitter
C)
Release of corticotrophin-releasing hormone
D)
Heightened precortex processes
Ans:
A
Feedback:
Excitatory neurotransmitters such as glutamate increase the probability that the target cell will fire an action potential by mediating the depolarization of the target cell. Excitatory transmitters serve as the body's stimulants promoting wakefulness, energy, and activity through regulating many of the body's most basic functions, including thought processes, higher thinking, and sympathetic activity. Distracters B, C, and D do not play a role in this process.
