You are studying a disease in which inhibition of sensory neurons is diminished,leading to more dramatic sensory sensations than are appropriate for stimulus strength.For example,when a person with this disease listens to a person talking in a normal voice,it sounds like they are yelling. Which neurotransmitter might be expressed at lower levels in this disease compared to a healthy individual?
A)Glutamate
B)Dopamine
C)Norepinephrine
D)Gamma-aminobutyric acid (GABA)
E)Beta-endorphin

Quizplus · Accepted Answer

Gamma-aminobutyric acid (GABA) is an inhibitory neurotransmitter that is responsible for reducing neural excitability. If its inhibition is diminished, as in this disease, the sensory neurons will be more excitable, and there will be more dramatic sensory sensations than appropriate for stimulus strength.
