Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
GABA is the main inhibitory neurotransmitter of the brain. It slows down nerve firing and helps the brain stay calm.
Step 2: Key Fact.
When GABA activity is low, the brain is less calm and nerve cells fire too easily. This is linked with anxiety disorders, which is why anti anxiety drugs raise GABA action.
Step 3: Check option (1) Paralysis.
Paralysis is linked with damage to nerves or the spinal cord, or with low acetylcholine action. It is not tied to low GABA. So (1) is wrong.
Step 4: Check option (2) Depression.
Depression is linked mainly with low serotonin and noradrenaline. So (2) is wrong.
Step 5: Check option (3) Anxiety disorders.
Low GABA is linked with anxiety disorders, so (3) is correct.
Step 6: Check option (4) Physical impairment.
This is a general term and has no direct link with GABA. So (4) is wrong.
Final Answer:
