Intrinsic Features of the Multisensory Cortical Area LRSS in the Ferret

Environmental events simultaneously transduced by more than one sensory modality underlie multisensory processing in the CNS. While most studies of multisensory processing examine functional effects, none have evaluated the influence of local or columnar circuitry. The goal of the present study is to examine of local features of the ferret lateral rostral suprasylvian sulcus (LRSS), a multisensory cortex. Immunostaining revealed the cytoarchitectonic features of the LRSS: thick supragranular layers, a narrow layer IV, and moderately stained but differentiated infragranular layers. Golgi-Cox techniques were used with light microscopy and digital reconstruction to document neuronal morphology. Among the 90 reconstructed neurons, 4 distinct forms or pyramidal and 2 types of non-pyramidal neurons were found. Measurement of maximal dendritic spread indicates that a cortical column in the LRSS was 250.9 um in diameter. These results describe local features of the LRSS upon which future experiments of intrinsic circuitry will be based.
