Abstract
What visual inputs best trigger activity for a given neuron in cortex and what type of semantic information may guide those neuronal responses? We revisit the methodologies used so far to design visual experiments, and what those methodologies have taught us about neural coding in visual cortex. Despite heroic and seminal work in ventral visual cortex, we still do not know what types of visual features are optimal for cortical neurons. We briefly review state-of-the-art ...
