Question

Quizplus · Accepted Answer

The olfactory bulbs are responsible for processing information related to smell. When Arjun smells the grass after it rains, his olfactory bulbs have received signals from neurons in his sinus cavity that are responsible for detecting the scent of the grass. The thalamus is responsible for relaying sensory information to the appropriate area of the brain, but it does not directly process information related to smell. The optic factory bulbs and the hippocampus are not involved in the sense of smell.
