title: Changes in emotionality following section of the tractus occipito-mesencephalicus in the barbary dove (Streptopelia risoria).
abstract: Section of the efferent pathways from the archistriatum in the Barbary Dove, leads to an immediate and persisting change in emotionality. The birds no longer react fearfully to the presence of a model predator, whereas control groups in which either the tractus occipito-mesencephalicus remains intact, or when the midline connections of the anterior commissure only are sectioned, continue to behave normally. This lack of responsiveness remains even under conditions of changing endogenous levels of hormone in the course of a normal breeding cycle.
