The present paper describes the results of architectural and
electrophysiological mapping observations of the medial bank of the
suprasylvian sulcus of the ferret immediately caudal to somatosensory
regions. The aim was to determine if the ferret possessed a homologous
cortical area to the anteromedial lateral suprasylvian visual area
(AMLS) of the domestic cat. We studied the architectural features and
visuotopic organization of a region that we now consider to be a
homologue to the cat AMLS. This area showed a distinct architecture
and retinotopic organization. The retinotopic map was complex in
nature with a bias towards representation of the lower visual field.
These features indicate that the region described here as AMLS in the
ferret is indeed a direct homologue of the previously described cat
AMLS and forms part of a hierarchy of cortical areas processing motion
in the ferret visual cortex. With the results of the present study and
those of earlier studies a total of twelve cortical visual areas have
been determined presently for the ferret, all of which appear to have
direct homologues with visual cortical areas in the cat (which has a
total of eighteen areas).
