Sound adds speed to visual perception

The traditional view of individual brain areas involved in perception of different sensory stimuli—i.e., one brain region involved in hearing and another involved in seeing—has been thrown into doubt in recent years. A new study published in the online open access journal BMC Neuroscience, shows that, in monkeys, the region involved in hearing can directly improve perception in the visual region, without the involvement of other structures to integrate the senses.
