A study by the University of Oxford has
stated that dancing skills depend on a person's genes. The study found that
people who were fast at picking up simple sequence of finger movements showed that
they had higher levels of a substance called GABA running in their brain. GABA
acts somewhat like a lubricant. It stops the brain cells from overheating and dampening
down of activity between them. Scientists used magnetic resonance spectroscopy
to measure GABA levels in the brain of the 12 participants. Using trans-cranial
stimulation scientists reduced the levels of GABA in the brain and it was found
that reducing GABA by 30% increased the speed of learning by 70%.
Dr. Charlotte Stagg said, "There is
considerable variability in motor learning behavior across individuals. We
aimed to test whether some of this variability could be explained by variation
in responsiveness of the GABA system."
Thus it was noted that those who were more responsive
to GABA were quicker in learning simple motor tasks. During learning, the
brains of such individuals showed greater activation in the motor cortex (it is
involved in planning and controlled movements). This study has been published
in the journal 'Current Biology'.
