    "abstract": "There is long history of studies documenting that some\nneurons respond to images of objects, faces, and scenes in a\nhighly selective manner. This includes neurons in the\nhuman hippocampus (e.g., the famous example of a neuron\nresponding to images of the actress Jennifer Aniston) and\nneurons in high-level visual cortex in monkey (for reviews\nsee Bowers, 2009; Ison, Quian Quiroga, & Fried, 2015).\nThese findings have led to a growing interest in the claim\nthat some neurons code for information in a localist\n(‘grandmother cell’) manner, as reflected in the many\ncontributions to a recent special issue on this topic in the\njournal Language, Cognition, & Neuroscience (Bowers,\n2017).\nBy contrast, it is only recently that interest in\ncharacterizing the selectivity of single units in connectionist\nnetworks has gathered speed. Critically, these studies also\nshow that networks learn highly selective representations\nunder a number of conditions, as detailed below. In this talk\nI will summarize recent research in my lab that explores the\nconditions in which artificial networks learn selective codes,\nand research comparing the responses of selective neurons\nand localist representations used in cognitive models. These\nfindings suggest when and why some neurons in cortex\nrespond in a highly selective manner, and highlight the\nbiological plausibility of localist models in psychology.",
