Electrical Mind Stimulation Not a Reminiscence Booster: Research
WEDNESDAY, Dec. 7, 2016 (HealthDay Information) -- Deep mind stimulation doesn't enhance reminiscence, and may very well hurt it, a brand new examine contends.
In deep mind stimulation, electrodes are implanted into the mind and present is handed via them to stimulate close by neurons, or mind cells. This examine included epilepsy sufferers who already had the electrodes implanted to map their seizures.
The Columbia College researchers stimulated areas of the mind identified to be concerned in making reminiscences, however not one of the 49 volunteers confirmed enhancements in reminiscence. Actually, their reminiscence declined 5 to 20 % after stimulation.
The discovering, printed Dec. 7 within the journal Neuron, contradicts earlier analysis suggesting that deep mind stimulation improves reminiscence, the researchers behind the brand new examine mentioned. That 2012 examine solely concerned seven contributors.
Nevertheless, the authors of this newest examine mentioned their findings do not rule out deep mind stimulation as a doable remedy for individuals with reminiscence issues brought on by damage or illness. It might simply require a distinct method, they mentioned.
"We might have a distinct form of stimulation protocol to have an effect on this area in a very good path," mentioned lead investigator Joshua Jacobs, an assistant professor of biomedical engineering.
"The straightforward method to stimulation does not work very properly, so we're attempting to develop a extra superior method," he mentioned in a journal information launch.
