Multisensory integration: vision boosts information through suppression in auditory cortex.
Signals from non-primary modalities can influence neural activity in 'unimodal' sensory areas of the neocortex, but whether this 'extra-modal' influence has any relevant consequences for neural coding has been unclear. Recent findings show that vision enhances the information content of neural signals in auditory cortex, but in a counter-intuitive fashion.
