Humans have no difficulty identifying an object they have previously interacted w/ only thru touch. How is this done?
Polymodal cortex combine information from varying sensory sources.
Sensory processing is more important & has increased neural activity
Tactile info is much more complex than what is required for object recog
Sensory & motor systems are the same thing as far as the cortex is concerne
