The motor cortex is the region of the cerebral cortex involved in the planning, control, and execution of voluntary movements. The motor cortex is an area of the frontal lobe located in the posterior precentral gyrus immediately anterior to the central sulcus. Motor cortex controls different muscle groups
The primary motor cortex (Brodmann area 4) is a brain region that in humans is located in the dorsal portion of the frontal lobe. It is the primary region of the motor system and works in association with other motor areas including premotor cortex , the supplementary motor area , posterior parietal cortex , and several subcortical brain ...
In a number of cases, brain areas are organized into topographic maps, where adjoining bits of the cortex correspond to adjoining parts of the body, or of some more abstract entity. A simple example of this type of correspondence is the primary motor cortex, a strip of tissue running along the anterior edge of the central sulcus. Motor areas ...
It contains the motor cortex, which is involved in planning and coordinating movement; the prefrontal cortex, which is responsible for higher-level cognitive functioning; and Broca's area, which is essential for language production. [79] The motor system of the brain is responsible for the generation and control of movement. [80]
It is located in the posterior portion of the frontal lobe. Brodmann area 4 is part of the precentral gyrus . The borders of this area are: the precentral sulcus in front ( anteriorly ), the medial longitudinal fissure at the top ( medially ), the central sulcus in back ( posteriorly ), and the lateral sulcus along the bottom ( laterally ).
Many of the existing topographic maps have been further studied or refined using fMRI. For example, Hubel and Wiesel originally studied the retinotopic maps in the primary visual cortex using single-cell recording. Recently, however, imaging of the retinotopic map in the cortex and in sub-cortical areas, such as the lateral geniculate nucleus ...
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
Brain mapping – set of neuroscience techniques predicated on the mapping of (biological) quantities or properties onto spatial representations of the (human or non-human) brain resulting in maps. Brain mapping is further defined as the study of the anatomy and function of the brain and spinal cord through the use of imaging (including intra ...
