Until recently many scientists believed that we only used one side of our brain to speak, however, a new study conducted by New York University and NYU Langone Medical Center, says that we actually use both.
The data for this study was taken from a group of patients that were being treated for epilepsy. Electrodes were placed directly inside and outside their brains as they were performing various thinking tasks.
All of the people in the study were asked to say words like "kig" and "pob" in order to see the effect of speech, and not language, on the brain, according to Science World Report. Because words like these had no meaning in language the scans showed activity on both sides of the brain when speech was engaged.
According to Medical News Today, most studies prior to this that have concluded that speech and language only occur on one side of the brain have relied on indirect measurement of brain activity.
Author of the study, Bijan Pesaran said that advances like this will help in the future to find ways to help people who have suffered from strokes or other medical trouble can learn to talk again.
