    Our new preprint is out! We find that the cortical feedback to V1 during visual mental imagery and illusory perception is decodable from distinct layers (mental imagery: deep, illusory perception: superficial layers). With and .

    Memory & pattern similarity for objects! Hippocampus helps protects against false memories by dissociating the neural similarity of exemplars in visual ctx. Cortical overlap and cortical-hippocampal interactions predict subsequent true and false memory.

    Layer-fMRI paper from earlier this month: Remi Gau aims high and tries to investigate two neuroscience concepts at once. Attention and multisensory integration effects are teased apart by means of 6 task conditions in 4 areas! Wow

    Object-oriented images cause boundary extension — but scene-oriented images cause boundary contraction. This happens even when participants are copying an image right in front of them This paper by & looks amazing!

    Awesome new paper by et al. showing that internal models of visual scenes – transmitted to V1 via cortical feedback - resemble sketches more than the actual visual scenes themselves.
