Cortex somatosensoriel
See also: Cortex (homonymy)
The somato-sensory cortex (somesthesic) receives information coming from the surface of the body via neurons sensitive relay and neurons…
The electric stimulation of the surface of the somato-sensory cortex is at the origin of phantom somatic feelings because electric stimulation MIME the arrival of information coming from the surface of the body (hot, cold, internal or external pains…).
This organization resulting in recognizing for each point of the somato-sensory cortex a corresponding part of the body is called somatotopie .
The somatotopic charts obtained on the level of the somato-sensory cortex by the methods of microphone-stimulations can be represented in the shape of a small man called sensitive Homonculus (disproportionate compared to the real form of the subject).
