New Delhi :  

A person’s brain might be ready for action even he is taking rest, a new study suggests.

The researchers studied brain network interactions between two important regions of brain, namely the dorsal anterior cingulate cortex (dACC) -- used for control -- and the supplementary motor area (SMA) -- used for motor movements during motor control behavior, for example tapping forefinger to a visual cue, in the study.

The results, published in the jounal PLoS One, showed that there was increase in the network interactions from the SMA to the dACC, during the rest time that alternated between the motor behavior risk.

"These results suggest that directional interactions from the SMA to the dACC during the rest period may in fact potentiate task-related interactions in the opposite direction," said Vaibhav Diwadkar, Professor at Wayne State University in Michigan, US.

A simple experiment task was used by the team for the study, with each participant performing a simple motor control behavior- tapping their forefinger to visual cue- that changed between behavior and rest. Functional MRI was used for acquiring brain activity.

Not only are the aspects of normative brain function revealed by the results but new directions for characterizing disordered network interactions  in neuropsychiatric syndromes may also be provided by the results, Diwadkar added.
