A quantative reassessment of speed tuning in the accessory optic system and pretectum of pigeons

Winship, Ian R; Crowder, Nathan; Wylie, Douglas R W


The correlation model of motion detection has been used to describe visual motion processing in the pretectum and accessory optic system (AOS). One feature of correlation detectors is that they are tuned to a particular temporal frequency (TF) independent of the spatial frequency (SF) but not to a particular stimulus speed (speed = TF/SF). Previous work has suggested that a subset of neurons in the AOS and pretectum of pigeons show apparent speed tuning. However, this study used relatively...[Show more]
