In neuroanatomy, the paracentral lobule is on the medial surface of the cerebral hemisphere and is the continuation of the precentral and postcentral gyri.The paracentral lobule controls motor and sensory innervations of the contralateral lower extremity.
The paracentral sulcus is a sulcus of the brain. It forms the paracentral lobule's anterior border. [1] It is part of the cingulate sulcus. Gallery
Furthermore, cells in the parasubiculum, and neighboring presubiculum, fire in relation to the animal's location in space, suggesting properties similar to place cells. It is postulated that this area may play an integral role in spatial navigation and the integration of head-directional information (Chrobak & Buzsáki, 1994; Taube, 1995).
Sensorimotor Anterior Region. This occurs around the margin of the cingulate sulcus ( blue in figure) and is connected with sensorimotor areas of the cerebral cortex such as the paracentral lobule, supplementary motor area, premotor cortex, somatosensory area (Brodmann area 2), parietal operculum and insula. fMRI Research upon humans finds a connection with the caudalmost part of ...
It is located on the anterior paracentral lobule on the medial surface. 2. The premotor cortex is responsible for some aspects of motor control, possibly including the preparation for movement, the sensory guidance of movement, the spatial guidance of reaching, or the direct control of some movements with an emphasis on control of proximal and ...
Frank's sign is a diagonal crease in the ear lobe extending from the tragus across the lobule to the rear edge of the auricle. [1] The sign is named after Sanders T. Frank. [1] It has been hypothesised that Frank's sign is indicative of cardiovascular disease [2] [3] and/or diabetes. [4]
Brodmann area 43, the subcentral area, is a structurally distinct area of the cerebral cortex defined on the basis of cytoarchitecture.Along with Brodmann Area 1, 2, and 3, Brodmann area 43 is a subdivision of the postcentral region of the brain, [1] suggesting a somatosensory ('feeling of the body') function.
Coronary CT angiography (CTA or CCTA) is the use of computed tomography (CT) angiography to assess the coronary arteries of the heart.The patient receives an intravenous injection of radiocontrast and then the heart is scanned using a high speed CT scanner, allowing physicians to assess the extent of occlusion in the coronary arteries, usually in order to diagnose coronary artery disease.
