The present study was conducted to determine if similar connections occur in other higher mammals such as carnivores (ferrets; Mustela putorius). Large injections of sensitive neuroanatomical tracer were placed within the core areas of auditory cortex in 3 ferrets. After transport and processing, labeled axon terminals were found not in primary visual cortex, but in area 19, or V3. Injection of tracer into V3 of 3 additional ferrets produced retrogradely labeled neurons not in the core region of auditory cortex, but along its posterior borders. These data indicate that cross-modal connections occur in the ferret cortex, but do not support the notion that they exist between the primary representations of the different sensory modalities.","abstract_html":"Recent studies have shown that neuronal connections occur between primary auditory and visual cortices of the primate (Falchier et al., 2002; Rockland and Ojima, 2003), and it has been suggested that these projections are involved in multisensory processing in these lower-level, core areas of cortex.
