Assessment and comparison of auditory and visual reaction time in abacus trained and untrained students aged 8 to 13 years in the south Indian population.

Background: Hand-eye coordination is essential for our daily activities. It involves the accuracy and concentration with which an individual performs tasks. Memory tasks like abacus involve the increased use of the superior and middle frontal gyrus, the motor region of the cerebral cortex, which improves the blood supply to this region, and nourishment to the neurons.
