Aiding in emotional processing and arousal functions are functions of the thalamus

Option A

Explanation:

Thalamus is located above the brain stem. Thalamus plays a vital sensory role which aids in the emotional processing and arousal functions. The thalamus has three main parts the anterior, medial and lateral.  

All sensory information except smell passes through the thalamus. Thalamus is so called as the relay station. It receives the information, modulates it and then sends it back as signals. A sensory impulse is create when touched and it is passed on to the cerebral cortex exhibiting the arousal .

after receiving a stimus, the sensory receptors send(s) signals to the appropriate area of the body.
