Monkeys, humans’ brain work the same way

New York – Speech sounds elicit comparable neural responses and stimulate the same region in the brain of humans, macaques and guinea pigs, according to a study that may help pave the way for better understanding and diagnosis of auditory processing deficits. A multidisciplinary group of University of Pittsburgh researchers reported in the journal eNeuro that the brain’s responses to sound — called frequency-following responses, or FFRs — can be recorded from small electrodes placed onto a person’s scalp.
