Temporal multiplexing of perception and memory codes in IT cortex.

ABSTRACT: A central assumption of neuroscience is that long-term memories are represented by the same brain areas that encode sensory stimuli¹. Neurons in inferotemporal (IT) cortex represent the sensory percept of visual objects using a distributed axis code^2-4. Whether and how the same IT neural population represents the long-term memory of visual objects remains unclear. Here we examined how familiar faces are encoded in the IT anterior medial face patch (AM), perirhinal face patch (PR) and temporal pole face patch (TP). In AM and PR we observed that the encoding axis for familiar faces is rotated relative to that for unfamiliar faces at long latency; in TP this memory-related rotation was much weaker. Contrary to previous claims, the relative response magnitude to familiar
