Delineating the posterior bank of the feline auditory cortex based on neurofilament proteins expressing SMI-32
The feline auditory cortex is understood to consist of 13 distinct subregions with unique anatomical and functional properties. Differential patterns of SMI-32 immunoreactivity are commonly used to identify the borders between these subregions; however, the detailed description of areal differences that is commonly cited did not include descriptions of the patterns observed along the posterior…
The feline auditory cortex is composed of 13 distinct subregions, each with its own unique anatomical and functional characteristics. Researchers have often utilized SMI-32 immunoreactivity to determine the boundaries between these subregions. However, the previous descriptions of areal differences did not encompass the patterns observed along the posterior ectosylvian gyrus.
The present study seeks to address this gap by offering a comprehensive dataset to delineate the dorsal, intermediate, and ventral divisions of the posterior ectosylvian gyrus, which correspond to auditory cortical regions dPE, iPE, and vPE, respectively. This is achieved by employing the same methodologies and criteria used in prior research.
The findings presented in this paper, along with those published previously, establish a standardized method for identifying all 13 auditory cortical subregions within this crucial model of auditory cortical structure and function.
