Brain Structures and Their Functions

Corpus Callosum: A large band of neural fibers connecting the left and right cerebral hemispheres, facilitating interhemispheric communication.
Choroid Plexus: A network of cells in the ventricles of the brain that produces cerebrospinal fluid (CSF), essential for cushioning the brain and maintaining its chemical stability.
Thalamus: Acts as a relay station for sensory information, processing and transmitting sensory data to appropriate areas of the cerebral cortex, playing a critical role in perception.
Corpora Quadrigemina: Located in the midbrain, this structure consists of four colliculi; the superior colliculi are involved in visual processing, while the inferior colliculi handle auditory information.
Optic Chiasma: The X-shaped structure formed by the crossing over of optic nerve fibers from both eyes, essential for depth perception and binocular vision.
Pituitary Gland: Often termed the "master gland," it regulates various hormonal functions in the body, influencing growth, metabolism, and reproductive processes.
Mammillary Body: Part of the limbic system, these structures are involved in memory processing and are critical for the formation of new memories.
Pons: A key structure in the brainstem, the pons is involved in regulating breathing, communication between different parts of the brain, and sensations such as hearing, taste, and balance.
