cerebrum
Cerebrum is the most prominent and developed region of the brain in humans. It is the site of functions as vision, hearing, touch, smell, voluntary muscle activity, speech and memory.
The cerebellum receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements. It coordinates voluntary movements such as posture, balance, coordination and speech.
Optic lobe function is to process and integrate incoming optical data from the eyes, detecting visual information like shapes and movements.
Medulla oblongata process information to and from the spinal cord and the cerebellum. It helps regulate breathing, heart and blood vessel function, digestion, sneezing and swallowing.
