These ganglia form the basis for the peripheral nervous system’s (PNS) sensory and motor neurons that innervate various parts of the body. The vertebral segmentation is a process that forms a distinctive feature of the group. At first, somites form as a spherical epithelial structure with a central lumen lined by radially arranged cells.
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 ...
Studies have found the frontal lobes to be involved in the executive functions of the brain, which are higher level cognitive processes. [28] This control process is involved in the coordination, planning and organizing of actions towards an individual's goals. It contributes to such things as one's behaviour, language and reasoning.
Wound scars in the brain largely contain astrocytes. The extracellular matrix also provides support on the molecular level for the brain's cells, vehiculating substances to and from the blood vessels. At the organ level, the nervous system is composed of brain regions, such as the hippocampus in mammals or the mushroom bodies of the fruit fly. [11]

A murder investigation has been launched after a 17-year-old was fatally stabbed near a bus station. Police said Thomas Taylor was walking along Greenhill Street, close to Bedford Bus Station ...
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-operative, microscopic, endoscopic and multi-modality imaging), immunohistochemistry, molecular and optogenetics, stem cell and cellular biology, engineering (material, electrical and biomedical ...
An inflation gauge that is closely watched by the Federal Reserve barely rose last month in a sign that price pressures cooled after two months of sharp gains. The milder inflation figures arrive ...
