title: Long-lasting evoked potential and repetitive firing recorded from the carp optic tectum in Cl-deficient medium in vitro.
abstract: Evoked potentials of the carp optic tectum following optic tract stimulation were examined in vitro. When the standard medium was replaced by Cl-deficient medium, the amplitude of the potential was augmented and the time course was prolonged. Following these changes, a long-lasting negative potential appeared in the deep layers. The involvement of a reverberating circuit is discussed.
