The “binding problem” is the issue of how we
ptsconvert sensory information into a pattern that produces movement
perceive visual, auditory and other aspects of our experiences as a single object
transfer information between the left and right hemispheres
communicate between the word comprehension and and word production areas of the brain.
perceive visual, auditory and other aspects of our experiences as a single object
