Brain ‘tickling’ can boost your memory: Here’s how!

Tickling the brain with low- intensity electrical stimulation in a specific area can improve verbal memory, a study has found. Researchers found word recall was enhanced with stimulation of the brain’s lateral temporal cortex, the regions on the sides of the head by the temples and ears. Patients recalled more words from a previously viewed list when low-amplitude electrical stimulation was delivered to the brain.

“The most exciting finding of this research is that our memory for language information can be improved by directly stimulating this underexplored brain area,” said Michal Kucewicz, a researcher at Mayo Clinic in the US. Memory impairments are a prevalent, costly problem in many brain diseases. Medication and behavioral therapies have limited effectiveness in many cases.

“While electrical stimulation of the brain is emerging as potential therapy for a wide range of neurological and psychiatric diseases, little is known about its effect on memory,” said Gregory Worrell, senior author of the the study published in the journal Brain. “The next step for this project is to determine how to best apply electrical current in terms of the exact location within this area of the brain, timing and parameters of stimulation,” said Brent Berry, researcher at the Mayo …read more
