[Study of the cortical field potentials produced by weak light stimulation in adult rabbits]
Abstract:
On a chronic preparation of an adult Rabbit, the cortical visual evoked response, produced by a weak luminous stimulation activating only the scotopic system is characterized by the suppression of the early surface-positive phase and by a lengthening of the latencies of the following deflection. The profile of the fields of potential corresponding to the various defletions in relation to the depth, has been investigated.
