Research interests: Neural basis of vision, audition,
multisensory integration, sensorimotor integration, motor control
How do our senses
work together? Our eyes and ears
cooperate to help us understand our environment. We frequently perceive visual and auditory
stimuli as being bound together if they seem likely to have arisen from a
common source. That's why we tend not to
notice that the speakers on TV sets or in movie theatres are located beside,
and not behind, the screen. Research in
my laboratory is devoted to investigating the question of how the brain
coordinates the information arising from the ears and eyes. Our findings challenge the historical view of
the brain's sensory processing as being automatic, autonomous, and immune from
outside influence. We have recently established that neurons in the auditory
pathway (inferior colliculus, auditory cortex) alter their responses to sound
depending on where the eyes are pointing.
This finding suggests that the different sensory pathways meddle in one
another's supposedly private affairs, making their respective influences felt
even at very early stages of processing. The process of bringing the signals
from two different sensory pathways into a common frame of reference begins at
a surprisingly early point along the primary sensory pathways.
