  • Descrição: The inferior temporal (IT) cortex of the macaque monkey plays a pivotal role in the visual recognition of objects. In the IT cortex, a feature-selective network formed by connecting subregions specialized for common visual features seems to be a basic strategy for processing biologically important visual features. Gloss perception plays an important role in the judgment of materials and conditions of objects and is a biologically significant visual function. In the present study, we attempted to determine whether a neural circuit specialized for processing information related to gloss perception exists in the IT cortex in one monkey. We injected retrograde tracer into a gloss-selective subregion in the IT cortex where gloss-selective neurons were clustered in the neural recording experiment, and anatomically examined its neural connections. We observed that retrogradely labeled neurons were densely accumulated in multiple locations in the posterior and anterior IT cortices. Based on the results of this case study, we will discuss the possibility that, together with the injection site, the sites with a dense cluster of labeled neurons form feature-selective neural circuits for the processing of gloss information in the IT cortex.
