The functional parts of forebrain are:

Explanation

The forebrain contains the cerebrum, limbic system, thalamus, pituarity gland and the olfactory bulb. The cerebrum is the largest part of the brain and is responsible for many of the higher-order functions of the brain, such as thinking, learning, and feeling emotions. The limbic system is a group of brain structures that are involved in emotion, behavior, and long-term memory. The thalamus is a relay station for sensory information. It receives sensory information from the eyes, ears, nose, tongue, and skin and sends it to the cerebrum. The thalamus also plays a role in pain perception and wakefulness.
