A temporary disruption of neural activity within a region of brain can be produced by
A) using a knife to cut brain tissue.
B) using an injection of muscimol into the brain region.
C) local heating of the brain using radiofrequency waves.
D) injection of kainic acid.
E) stimulation of bregma.

Question

Quizplus · Accepted Answer

Injecting muscimol into the brain region would produce a temporary disruption of neural activity within that region. Muscimol is a compound that activates receptors for gamma-aminobutyric acid (GABA), which is an inhibitory neurotransmitter. By activating these receptors, muscimol would effectively shut down neural activity in the region where it is injected, causing a temporary disruption of function. The other choices listed would not produce a temporary disruption of neural activity within a brain region.
