- Gray matter consists of densely packed neurons (nerve cells). It’s called “gray” because the concentrations of neurons give it a grayish, pinkish color when stained with certain materials. These cells are directly involved in many thinking skills, emotions, and muscle movement.
Jul 27, 2018 · Gray matter, also spelled grey matter (British spelling) and also called substantia grisea, is the part of the brain that is controlled by the true dendrites (the short branching fibers that carry messages and impulses to the cell body) and nerve cell bodies (which bring information to the neurons).

The sensory areas of the cerebral cortex receive sensory information from the senses and environmental stimuli. This information is also processed by the sensory areas to give meaning to this information. The sensory areas include the visual cortex, the somatosensory cortex, the auditory cortex, and the gustatory cortex. The visual cortex is an are...
The motor areas of the cerebral cortex are involved in the regulation and initiation of voluntary movement. These areas are primarily found within the frontal lobes and include the primary motor cortex, premotor cortex, and the supplementary cortex. The primary motor cortex is associated with the coordination and initiation of motor movements. Each...
The association areas are spread throughout the cerebral cortex in the four lobes. These areas act by integrating information from these brain regions, often adding more complexity to their functions. These association areas can also form connections to sensory and motor areas to give meaning to and organize information in these areas. Association ...
Brodmann Areas,named after German neurologist Korbinian Brodmann, are a system for mapping and categorizing regions of the human cerebral cortex based on their distinct cellular architecture and functions. These numbered areas, which range from 1 to 52, provide a structural framework for understanding different brain functions, such as sensory proc...

Jun 13, 2024 · Grey matter consists of neuronal cell bodies, dendrites, and unmyelinated axons, primarily involved in processing and integrating information. White matter is composed of myelinated axons, facilitating communication between different brain regions through rapid signal transmission.
Gray matter is a major component of the central nervous system, consisting primarily of neuronal cell bodies, dendrites, unmyelinated axons, and glial cells. It is involved in muscle control, sensory perception such as seeing and hearing, memory, emotions, and speech.
