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 rest of the cortex is of allocortex, which has three or four layers. [7] The cortex is mapped by divisions into about fifty different functional areas known as Brodmann's areas. These areas are distinctly different when seen under a microscope. [22] The cortex is divided into two main functional areas – a motor cortex and a sensory cortex ...
The primary gustatory cortex (G) is located near the somatotopic region for the tongue (S1), in the insular cortex deep in the lateral fissure with the secondary taste areas in the opercula. [ 11 ] The peripheral taste system likely maintains a specific relationship between taste bud cells selectively responsive to one taste quality and the ...
Neural top–down control of physiology concerns the direct regulation by the brain of physiological functions (in addition to smooth muscle and glandular ones). Cellular functions include the immune system’s production of T-lymphocytes and antibodies, and nonimmune related homeostatic functions such as liver gluconeogenesis, sodium reabsorption, osmoregulation, and brown adipose tissue ...
The cells have their bodies in the cerebral cortex, and the axons form the bulk of the pyramidal tracts. [4] The nerve axons travel from the cortex through the posterior limb of internal capsule, through the cerebral peduncle and into the brainstem and anterior medulla oblongata. Here they form two prominences called the medulla oblongatary ...
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] These regions are often modular and serve a particular role within the general systemic pathways of the nervous system.
