Parts of the Brain

Function: The largest part of the brain, responsible for higher brain functions such as thinking, memory, reasoning, and voluntary muscle movements.
Divided into Hemispheres:
- Left Hemisphere: Controls the right side of the body, involved in logical thinking, language, and mathematics.
- Right Hemisphere: Controls the left side of the body, involved in creativity, spatial ability, and recognizing patterns.
Lobes of the Cerebrum:
- Frontal Lobe: Responsible for decision-making, problem-solving, planning, and controlling behavior and emotions.
- Parietal Lobe: Processes sensory information such as touch, temperature, and pain. Also responsible for spatial orientation.
- Occipital Lobe: Responsible for processing visual information.
- Temporal Lobe: Involved in auditory processing, memory, and language comprehension.

Function: Coordinates voluntary muscle movements and helps maintain posture and balance. It also plays a role in motor learning and fine-tuning movements.

Function: Controls the basic life functions such as heartbeat, breathing, swallowing, and digestion.
Parts of the Brainstem:
- Midbrain: Involved in vision, hearing, eye movement, and body movement. It also controls alertness and arousal.
- Pons: Relays signals between the cerebrum and cerebellum. It is involved in sleep regulation, breathing, and facial expressions.
- Medulla Oblongata: Regulates essential autonomic functions like heart rate, blood pressure, and breathing. It is critical for survival.

Function: Acts as the brain’s relay station, sending sensory information (except smell) to the appropriate areas of the cortex for processing. It also plays a role in regulating sleep and wakefulness.

Function: Regulates critical body functions like temperature, hunger, thirst, and sleep. It also controls the pituitary gland, which influences hormones and the endocrine system.

Function: A group of structures involved in emotions, motivation, learning, and memory. Key components include:
- Amygdala: Involved in emotions, especially fear and aggression.
- Hippocampus: Plays a critical role in memory formation and spatial navigation.

Function: Involved in the control of movement, coordination, and motor learning. It helps in the initiation of voluntary movements and the regulation of motor activity.

Function: A thick band of nerve fibers that connects the left and right hemispheres of the cerebrum, allowing communication between the two sides of the brain.
