Eye movements evoked from telencephalic stimulations in the piranha (Serrasalmus nattereri).
The telencephalon of spinally transsected, unanesthetized piranhas was systematically stimulated with microelectrodes to scan for eye movement inducing (EMI) sites which were then identified by histological means. EMI sites were found clustered in several distinct central and medial telencephalic areas. Various types of eye movements were evoked from these sites often in combination with movements of the jaw, gills and pectoral fins. It is concluded that eye movements evoked from the telencephalon may be mediated by the optic tectum.
