Study: Aging brain hemispheres increase communication to maintain function

A new study published in Human Brain Mapping indicatesthat as the brain ages, it increases communication between the hemispheres tomake up for the negative effects of aging, according to Medicalpress.

Other studies have shown thatolder brains feature more bilateral communication than younger brains, but thisstudy “suggests that the aging brain maintains healthy cognitive function byincreasing bilateral communication,” said lead author Simon Davis, PhD.

To conduct the study, researchersutilized trans-cranial magnetic stimulation (TMS) to modify brain activitywhile participants completed a memory task. “When researchers applied TMS at afrequency that depressed activity in one memory region in the left hemisphere,communication increased with the same region in the right hemisphere,suggesting the right hemisphere was compensating to help with the task,”Medical Press reports.

“Good roads make for efficienttravel, and the brain is no different,” Davis said. “By taking advantage ofavailable pathways, aging brains may find an alternate route to complete theneural computations necessary for functioning.”
