3. Read each of the following two statements, Assertion (A) and Reason (R) and indicate your answer using the codes given below: [DEC 2014]

Assertion (A) A neuron without an Axon cannot transmit information even to other neurons immediately adjacent to it.

Reason (R) Dendrite receives information from other neurons and Axons transmit it forward.

Codes:

(1) Both (A) and (R) are true and (R) is the correct explanation of (A)

(2) Both (A) and (R) are true, but (R) is not the correct explanation of (A)

(3) (A) is true, but (R) is false

(4) (A) is false, but (R) is true

4. Read each of the following two statements, Assertion (A) and Reason (R) and indicate your answer using the codes given below: [DEC 2014]

Assertion (A) The orbital frontal cortex and the basal ganglia, especially the caudate nucleus, are the brain structures most often implicated in obsessive compulsive disorder.

Reason (R) Reduced metabolic activity has been found in both the orbital frontal cortex and the caudate nucleus in people with obsessive compulsive disorder.

Codes:

(1) Both (A) and (R) are true and (R) is the correct explanation of (A)

(2) Both (A) and (R) are true, but (R) is not the correct explanation of (A)

(3) (A) is true, but (R) is false

(4) (A) is false, but (R) is true

Reason (R) Synapses produce inhibitory post-synaptic potential also in post-synaptic neuron.

Codes:

(1) Both (A) and (R) are true and (R) is the correct explanation of (A)

(2) Both (A) and (R) are true, but (R) is not the correct explanation of (A)
