Medulla oblongata is the bottom-most part of your brain. Its location means it's where your brain and spinal cord connect, making it a key conduit for nerve signals to and from your body. It also helps control vital processes like your heartbeat, breathing and blood pressure.

The cerebellum coordinates and regulates muscle tone, balance, and posture. The cerebellum plays a role in higher-order functions, including cognitive, emotional, and reward processes.

The Cerebrum is the largest part of the brain, making up about 80% of it. It's responsible for memory, intelligence, emotions, personality, and more. It is the center for intelligence, memory, and emotions. It coordinates voluntary muscle movements and helps in maintaining posture and balance.

The olfactory lobe's main function is to transmit the sense of smell.
