Read the following matches carefully.

I) Corpus callosum: Connects both right and left cerebellar hemispheres.

II) Limbic system: Regulation of sexual behaviour and emotions with the hypothalamus.

III) Association areas: Responsible for intersensory associations, memory and communication.

IV) Medulla oblongata: Controls motivation and urge for eating and drinking .

How many of the above matches is/are incorrect?

Unipolar neurons can be seen in the

Assertion: Reflex arc comprises of at least one afferent neuron, one efferent neuron and a part of PNS.

Reason: The afferent neuron receives signal from a sensory organ and transmits the impulse via a dorsal nerve root into the CNS.

A neuron is said to be in resting state when,

II. plasma membrane is electrically positive outside and negative inside
III. the nerve fibre is stimulated mechanically or electrically
IV. plasma membrane is negative outside and positive inside
