Neurocognitive mapping for visuospatial tasks has been carried out in healthy volunteers and chronic alcoholics, using BOLD technique. Significant activations observed in the parietal, occipital lobes and frontal cortex in healthy subjects are attributed to spatial representation and the processing of spatial information and attention shifting. In alcoholics, activations were quite less in the above regions as compared to controls, indicating impairment.
