Visuomotor binding in older adults

Brain Cogn. 2010 Dec;74(3):239-43. doi: 10.1016/j.bandc.2010.08.002.

Abstract

Action integration is the process through which actions performed on a stimulus and perceptual aspects of the stimulus become bound as a unitary object. This process appears to be controlled by the dopaminergic system in the prefrontal cortex, an area that is known to decrease in volume and dopamine functioning in older adults. Although the decline should lead to reduced action integration in older adults, we found equivalent integration in both young and older adults. This indicates that older adults may be able to compensate for their dopaminergic deficiencies by activating additional neural networks that are not used by young adults.
