Still, we are missing a mechanistic account of how these representations come about. Here we provide a simple explanation for a range of experimental findings, in light of prefrontal circuits adapting to task constraints by reward-dependent learning. In particular, we model a neural network shaped by reward-modulated spike-timing dependent plasticity (r-STDP) and homeostatic plasticity (intrinsic excitability and synaptic scaling). We show that the experimentally-observed neural representations naturally emerge in an initially unstructured circuit as it learns to solve several working memory tasks. These results point to a critical, and previously unappreciated, role for reward-dependent learning in shaping prefrontal cortex activity."}],"oa":1,"date_updated":"2021-01-12T06:54:09Z","title":"Emergence of task-dependent representations in working memory circuits","user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","department":[{"_id":"GaTk"}],"publication":"Frontiers in Computational Neuroscience","main_file_link":[{"open_access":"1","url":"http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4035833/"}],"publist_id":"5163","author":[{"first_name":"Cristina","id":"3933349E-F248-11E8-B48F-1D18A9856A87","full_name":"Savin, Cristina","last_name":"Savin"},{"last_name":"Triesch","full_name":"Triesch, Jochen","first_name":"Jochen"}],"doi":"10.3389/fncom.2014.00057","publication_status":"published","year":"2014","quality_controlled":"1","language":[{"iso":"eng"}],"scopus_import":1,"day":"28","publisher":"Frontiers Research Foundation","intvolume":"         8","acknowledgement":"Supported in part by EC MEXT project PLICON and the LOEWE-Program “Neuronal Coordination Research Focus Frankfurt” (NeFF).
