Oct 1, 2024 · Function. The Central Nervous System (CNS) is the control center of the body, responsible for processing sensory information, initiating and regulating motor responses, and managing higher cognitive functions. The CNS includes the brain and spinal cord, both of which play distinct yet interconnected roles in coordinating bodily functions.
Aug 21, 2024 · The cerebrum, also called the telencephalon, refers to the two cerebral hemispheres (right and left) which form the largest part of the brain. It sits mainly in the anterior and middle cranial fossae of the skull.

The most rostral portion of the frontal cortex is known as the prefrontal cortex, which encompasses the superior, middle and inferior frontal gyri of the frontal lobe. It plays a crucial role in the processing of intellectual and emotional information, including aggression, and facilitates judgement and decision-making.
The motor cortex corresponds to the precentral gyrus of the frontal lobe. The precentral gyrus contains the primary motor cortex(Brodmann area 4), which is responsible for integrating signals from different brain regions to modulate motor function. The primary motor cortex is where the corticospinal tract originates. Anterior to the primary motor c...
The inferior frontal gyrus is divided into three parts: i) the pars opercularis, ii) the pars triangularis, and iii) the pars orbitalis. Pars opercularis refers to the most dorsal part of the gyrus, pars triangularis is the middle triangularly-shaped part, while the pars orbitalis represents the most ventral part of the gyrus. Functionally, the par...

The hypothalamus is located above the pituitary gland and sends it chemical messages that control its function. It regulates body temperature, synchronizes sleep patterns, controls hunger and thirst and also plays a role in some aspects of memory and emotion.
Anatomy: The temporal lobes sit at the bottom middle portion of the brain, just behind the temples. Key structures include the auditory cortex and Wernicke’s area. The auditory cortex performs basic and higher functions of hearing and Wernicke’s area interprets written and spoken speech.
Mar 17, 2023 · It is located anterior to the cerebellum, between the base of the cerebrum and the spinal cord. Go to: Issues of Concern. Studies of brain function have focused on analyzing the variations of the electrical activity produced by the application of sensory stimuli.
Your cerebellum is a small part of your brain located at the bottom of this organ near the back of your head. It processes and regulates signals between other parts of your brain and body, and is involved in coordinating functions of your body (for example, walking).
