Cortical representations of one or two items held in working memory. (A and B) Two‐ and three‐dimensional representations of remembered locations were reconstructed using MVPA (multivoxel pattern analysis) from an fMRI study with a surface fitted to the average reconstruction. (C) Spatial representations in memory became coarser from V1 (primary visual cortex) through to parietal regions within the intraparietal sulcus (IPS0–3) and frontal eye fields (sPCS, superior precentral sulcus). Crucially, there was a fall in the amplitude of the representation from holding one to two items in memory across many early visual areas and some parietal regions. Adapted from Ref. 28.
