SmI cortical barrels in an australian marsupial, Trichosurus vulpecula (brush‐tailed possum): Structural organization, patterned distribution, and somatotopic relationships

This study reports on the cerebral cortex of an Australian marsupial, Trichosurus vulpecula (brush‐tailed possum). It consists of an analysis of layer IV of somatosensory cortex in tangential sections of flattened specimens and in oblique radial sections stained to show Nissl substance or myelin, or tested for succinic dehydrogenase. It includes results of electrophysiological mapping experiments that ascertained the somatotopic significance of the cytoarchitecture of this cortical region.
