StarStarStarStar

Hypothalamus

StarStarStarStar

A neural structure that directs several important functions, such as the autonomic nervous system, body temperature, hunger, thirst, fatigue, and circadian cycles.

StarStarStarStar

Corpus Callosum

StarStarStarStar

A wide, flat bundle of neural fibers beneath the cortex that connects the left and right cerebral hemispheres and provides communication between them.

StarStarStarStar

Cerebellum

StarStarStarStar

Responsible for coordinating voluntary movements such as posture, balance, coordination, and speech, resulting in smooth and balanced muscular activity.

StarStarStarStar

Occipital Lobe

StarStarStarStar

Primary function is the processing, integration, interpretation of vision and visual stimuli.

StarStarStarStar

Parietal Lobe

StarStarStarStar

Processes sensory information it receives from the outside world, mainly relating to spatial sense and navigation.

StarStarStarStar

Orbitofrontal Cortex

StarStarStarStar

Involved in the cognitive process of decision-making and reward in the context of emotional and social behavior.

StarStarStarStar

Prefrontal Cortex

StarStarStarStar

Involved in complex behaviors such as planning, decision making, and moderating social behavior. It is also key to personality expression.

StarStarStarStar

Wernicke's Area

StarStarStarStar

Important for language development and comprehension. Damage to this area can result in receptive aphasia, where one can speak but not understand language.

StarStarStarStar

Broca's Area

StarStarStarStar

Responsible for language processing, speech production, and comprehension.

StarStarStarStar

Thalamus

StarStarStarStar

Functions as a relay station for almost all information that comes and goes to the cortex. It plays a role in pain sensation, attention, and alertness.

StarStarStarStar

Insula

StarStarStarStar

Involved in complex emotional and cognitive processing. The insula is believed to play a role in consciousness and the regulation of homeostasis.

StarStarStarStar

Pituitary Gland

StarStarStarStar

The pituitary gland is a hormone-producing gland considered the 'master gland' of the endocrine system, controlling the function of many other glands.

StarStarStarStar

Hippocampus

StarStarStarStar

Critical for the formation of new memories and is also associated with learning and emotions.

StarStarStarStar

Motor Cortex

StarStarStarStar

Responsible for the planning, control, and execution of voluntary movements. Part of the cerebral cortex.

StarStarStarStar

Anterior Cingulate Cortex (ACC)

StarStarStarStar

Functions include rational cognitive functions, such as reward anticipation, decision-making, empathy, impulse control, and emotion.

StarStarStarStar

Amygdala

StarStarStarStar

Involved in processing emotions such as fear, anger, and pleasure. It is also essential for emotional memory.

StarStarStarStar

Basal Ganglia

StarStarStarStar

Associated with a variety of functions, including control of voluntary motor movements, procedural learning, and routine behaviors or habits.

StarStarStarStar

Temporal Lobe

StarStarStarStar

Involved in processing auditory information and is also important for the processing of semantics in both speech and vision.

StarStarStarStar

Somatosensory Cortex

StarStarStarStar

Responsible for processing sensory input from the body. It includes mapping of the skin and internal organs to the brain.

StarStarStarStar

Brainstem

StarStarStarStar

Responsible for basic life functions such as breathing, heartbeat, and blood pressure. It is composed of the midbrain, pons, and medulla oblongata.
