A new study suggests that brain, stroke, head injuries, speech and communication disorders could be treated, as brain covers both the sides of the brain. This study debunk the belief that only one side o the brain is used for this task.
The findings improve understanding of the process of speech generation in the brain which could lead to new techniques to treat speech related disorders.
Previous researches on speech relied on studies that were measuring brain activities indirectly. This new study however examined the relation between speech and brain activity directly. Participants of this study had a direct and specialized electrodes implanted inside and on the surface of the brain.
Researchers focused on parts of the brain during speech. The participants were asked to repeat non-words like ‘kig’ and ‘pob’. Using non-words trigger brain activities enabled by the researchers to segregate speech from language.
The results indicated activity in both the sides of the brain for speech. With this great insight between the connection between brain and speech, we can work for the development of new and advanced ways to support those trying to regain the ability to speak after a stroke or head injury.
