\nSummary Theves et al. 2019 probe whether the hippocampus similarly encodes distances between points in an abstract space spanned by continuous stimulus-feature dimensions that were relevant to the acquisition of a novel concept<\/span><\/strong>. They find that, after learning, two-dimensional distances between individual positions in the abstract space were represented<\/strong> <\/span>in the hippocampal multivoxel pattern as well as in the univariate hippocampal signal as indexed by fMRI adaptation. These results support the notion that the hippocampus computes domain-general, multidimensional cognitive maps along continuous dimensions<\/span><\/strong>.<\/p>\n <\/p>\n For further info, please read the paper\u00a0Theves, S. et al. 2019.<\/p>\n
\nThe hippocampal formation encodes maps of the physical environment. A key question in neuroscience is whether its spatial coding principles also provide a universal metric for the organization of non-spatial information<\/strong><\/span>. Initial evidence comes from studies revealing directional modulation of fMRI responses in humans. However, a critical feature of a map-like representation is information about distances between locations, which has yet only been demonstrated for physical space<\/strong><\/span>.<\/p>\n![\"\"](\"https:\/\/pbs.twimg.com\/media\/D2MexUHWoAQH2Qr.jpg\")
