Object vision

The authors developed an optical imaging approach for mapping cortical functions through the intact skull in marmoset monkeys. Detailed functions and topographies were revealed in visual, auditory, and somatosensory cortices at mesoscopic scales.

Neural responses in the human primary visual cortex (V1) are shown here to be consistent with perception of the Muller-Lyer illusion but not for the curveball effect, demonstrating that V1 does not encode apparent position per se.

Using electroencephalography and functional magnetic resonance imaging, Graumann et al. examine where, how and when representations of object location and category emerge in the human brain.
