→Sensory processing: Rewritten first paragraph and vision section to improve specificity and clarity. Added image to help understand lateralization of visual processing.
The processing of basic sensorySensory information isfor lateralized by being divided intothe left and right sides of the body oris theoften spacelateralized arounddue theto bodynerve fiber [[decussation]].

In [[hearing]], about 90% of the neurons of the [[auditory nerve]] from one ear cross to project to the [[auditory cortex]] of the opposite hemisphere.
