MULTIPLE CHOICE

1. Glutamate plays a specific functional role in

a. synaptic plasticity.

b. anxiety reduction.

c. the action of alcohol.

d. seizure suppression.

2. The most abundant inhibitory neurotransmitter in the brain is

a. Acetylcholine

b. Dopamine

c. Glutamate

d. GABA

Solutions

Expert Solution

1. B. Anxiety reduction can be regulated by the neurotransmitters like seratonine and norepinephrine etc . So option B is incorrect.

C. The action of alcohol can be regulated by the gaba receptors. So option C is also incorrect.

D. Glutamate receptors involves in the facilitates seizure. So this is also incorrect.

A. Synaptic plasticity is the ability of synapse to strengthen or weaken over time in their activity. Glutamate is the major excitatory neurotransmitter in the central nervous system .

Increase number of the glutamate receptors leads to the increase glutamate synaptic function. So option A is correct.

2. Acetylcholine is excitatory neurotransmitter . Do option A is incorrect.

Dopamine is also excitatory neurotransmitter. So option B is also incorrect

GABA is acts as both excitatory and inhibitory neurotransmitter .So this is not exact option. GABA is consider as the 2nd most abundant inhibitory neurotransmitter in the brain.

C. Glutamate is the first most inhibitory neurotransmitter in the brain .So option C is correct .
