Topic: category selectivity

Across the primate neocortex, neurons dedicated to similar functions are likely to be found physically nearby. In the high-level visual cortex, this principle gives rise to cortical patches with distinct category selectivity that were previously observed across many species including macaque monkeys and humans. Models of visual cortex based on artificial neural networks (ANN) have been shown to contain internal representations that are remarkably similar to those observed in the visual cortex. However, unit selectivity in these models emerges without any particular spatial order (i.e. no topog

The last quarter century has provided extensive evidence that some regions of the human cortex are selectively engaged in processing a single specific domain of information, from faces, places, and bodies to language, music, and other people’s thoughts. This work dovetails with earlier theories in cognitive science highlighting domain specificity in human cognition, development, and evolution. But many questions remain unanswered about even the clearest cases of domain specificity in the brain, the selective engagement of the FFA, PPA, and EBA in the perception of faces, places, and bodies, r
