[Inhibition in neurology]

The author recalls three examples of inhibition in neurology: -- in the somatic sensory area inhibition halo around the excited zone; -- in the organisation of painful perception, inhibition by stages of nociceptive impulses; -- in anterior limbic system, inhibition of excitations without concern with the given operationnal programme. From these three examples, he recalls that inhibition and excitation always go together in the functioning of nervous system; but, between the acceptation of the work inhibition in the two first examples and the third one, an important semantic slipping happens. It squares with the crossing of the clinical level to the physiological level.
