[PMC free article] [PubMed] [Google Scholar]Le Merre P, Esmaeili V, Charrire E, Galan K, Salin PA, Petersen CCH, and Crochet S. that multiple hippocampal coding processes for unique types of salient features are distinguished by a Shank2-dependent mechanism and suggest that abnormally distorted hippocampal salience mapping may underlie cognitive and behavioral abnormalities in a subset of ASDs. In Brief Using longitudinal two-photon calcium imaging in mice during virtual navigation, Sato et al. demonstrate that separable and persistent neuronal subsets mediate the hippocampal over-representation of prize and landmark locations. Learning-induced over-representation of landmarks can be absent while fast over-representation of benefits is enhanced, inside a mouse style of autism missing (Won et al., 2012), a mouse style of ASD that does not have a glutamatergic postsynaptic scaffold protein, show selective lack…
