[KP-PC]

I Love your reply, Didier - especially its emphasis on cross-modal
integration.

Cheers, ken

| We are finding out that a good part of the
| brain (by which I assume you mean
| cortex) is multisensory. People tend to

| but typically, recordings are hard enough

| complex enough) that rarely does one lab
| study an area with respect to different modalities
| (visual, somatosensory, vestibular, auditory, etc).
| So using the above number you mention, 50%
| of the brain is visual, 50% is auditory, 50% is
| motor,  50 % is somatosensory, and about 90%
| is vestibular.
