title: Wulst lesions in pigeons disrupt go/no-go reversal.
abstract: Pigeons with lesions of either the Wulst or ectostriatum were compared to controls on reversal of a go/no-go pattern discrimination. The Wulst-lesioned animals were slower to acquire the response to the new S+ but were not different from the other groups on extinction of response to the old S+. The ectostriatum-lesioned group was not different from controls. The results extend the range of situations in which Wulst-lesioned pigeons have been found to show a reversal deficit and are consistent with the notion that Wulst lesions may disrupt learning.
