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.
