A cortical basis for perception of internal gut sensations

Omer Rafael-Izhaki, Stav Shtiglitz, Juliet Miller…·Yoav Livneh

Mice can report optogenetic activation of vagal gut mechanosensory neurons; insular cortex encodes perceptual report and causally affects detection only in a difficult psychophysics task, not simple detection.
