Differential roles of auditory and visual cortex for sensory detection in mice

Résumé

Sensory cortex encompasses the regions of the cerebral cortex that receive primary sensory inputs and is crucial for conscious sensory perception in humans. Yet, some forms of perception are possible without sensory cortex. For example in animal models, the association of a sound detection to a simple behavior resists to the inactivation of auditory cortex. In contrast, post-training inactivation experiments conducted in visual or somatosensory cortex led to much stronger effects. Here we show that muscimol inactivation of visual or auditory cortex in the same detection protocol transiently abolishes visual but not auditory detection. We also observe that cortex-dependency correlates with longer reaction times. This suggests that auditory cortex is more easily bypassed by other circuits for stimulus detection than other primary sensory areas, which may be due to timing differences between auditory and visual associations.
