Cross-Modal Projections From Auditory To Visual Cortices In The Ferret, Meng Y. Wang

Theses and Dissertations

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. 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 …
