The human brain is the central organ of the nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system ...
Precentral gyrus sensory homunculus. Somatotopy [a] is the point-for-point correspondence of an area of the body to a specific point on the central nervous system. [1] Typically, the area of the body corresponds to a point on the primary somatosensory cortex (postcentral gyrus).
The following diagram is provided as an overview of and topical guide to the human nervous system: Human nervous system. Human nervous system – the part of the human body that coordinates a person's voluntary and involuntary actions and transmits signals between different parts of the body.
A 2-D model of cortical sensory homunculus. A cortical homunculus (from Latin homunculus 'little man, miniature human' [1] [2]) is a distorted representation of the human body, based on a neurological "map" of the areas and portions of the human brain dedicated to processing motor functions, and/or sensory functions, for different parts of the body.

The extrastriate areas consist of visual areas 2, 3, 4, and 5 (also known as V2, V3, V4, and V5, or Brodmann area 18 and all Brodmann area 19). [ 1 ] Both hemispheres of the brain include a visual cortex; the visual cortex in the left hemisphere receives signals from the right visual field , and the visual cortex in the right hemisphere ...
Neuroplasticity – changes in a brain due to behavior, environment, aging, injury etc. Nonsynaptic plasticity – changes in the axon, dendrites, and soma of individual neurons; Parental brain – patterns in the brain of a new parent such as sensitivity towards infant cues, processing those cues and being motivated to engage with the infant
Brodmann areas 3, 1, and 2 make up the primary somatosensory cortex of the human brain (or S1). [2] Because Brodmann sliced the brain somewhat obliquely, he encountered area 1 first; however, from anterior to posterior , the Brodmann designations are 3, 1, and 2, respectively.
