The neurophysiology is the study of the functions Nervous system, resting on all the levels of description, of the molecular level up to the level more integrated neural networks.

It is a multi-field science, with the crossroads of other biological sciences (Neuroanatomie, Neuroendocrinologie, Neuropharmacologie, etc) and behavioral (Neuropsychologie, Psychiatrie…), in particular.

I. Introduction

Physiology: operation of the bodies

nervous system: exchange: brain, spinal-cord protected in limps cranial and spinal column

peripheral: cranial nerves (12p) and rachidian (31p), receivers sensory and driving termination

3 properties of nervous fabrics (neuron (unit functional of fabric): exitability, conductibility, communicability Emits electrical signals in answer has stimulation of propagation along dendrites and cellular bodies form PS, the long axon forms Pa.

Dendrites - > body cellular: centripetal transmission, cellulipète

Axon: cellular body - > end: centrifugal, cellulifugal transmission

Possible nerve impulse by protein in membrane neuron: channels ionic

Synapse: arrived Pa on synaptic pre neuron - > release neuro-transmitter in neurosynaptic slit which is fixed on receivers of membranes of the synaptic element post and involves a variation of the potential of membranes.
