Effects of asphyxia on the visual activity of the crayfish with neural deafferentation of the eyestalks

Abstract
Centripetal migration of distal pigments of the crayfish compound eye, is induced by light, by a protocerebral circadian pacemaker and among many other influences by asphyxia. The adaptive migration of those pigments, in this case, is accompanied by a clear neural hyperexcitability which can be suppressed by experimental deafferentation of the eyestalks.
