Resumen:
The Central Nervous System has a complex structural and functional organization. Among its functional properties we may emphasize sensorial processes, motor control, vegetative regulation, emotions and cognitive processes. The integrity of these functions allows organisms to maintain an interaction with environment; furthermore, sensorial activity assures communication with either internal or external milieu. Pain as a sensorial process is integrated by a sequence of neuronal signs with important bio-electrical and bio-chemical correlates, that advise about the eventual or current body tissue damage. Some of the neuronal cells are in charge of the noxious stimuli reception while others transmit this information to specific neuronal structures; certain cells, by the integration of this information, produce a conscious pain sensation; moreover. there are cells involved in the motor responses and, finally, cells that regulate the noxious information including the analgesia. This work points out general and basic relations between the nervous activity and the sensorial process specifically related with pain. In this sense we intend to give the reader a brief look at some of the sensorial system functions. For this purpose, we describe some electrophysiological data concerned with the diminution of pain responses and the alterations in the receptive fields during experimental noxious activation.
