Do you find it hard to focus? Do you often go into a room and immediately forget why you went in there? Well, scientists have found evidence for a new treatment for your bad memory: shooting frickin’ lasers at your brain.
, an international team of researchers found that laser light therapy helped improve short-term memory in participants by up to 25 percent. The treatment, dubbed transcranial photobiomodulation , involves a device worn over the skull that fires the laser into the right prefrontal cortex—an area of the brain responsible for working memory.
The study’s authors found that the participants’ memories improved after just seven minutes of treatment—and could pave the way for a non-invasive treatment to boost memory and cognition. “People with conditions like ADHD [attention deficit hyperactivity disorder] or other attention-related conditions could benefit from this type of treatment, which is safe, simple and non-invasive, with no side-effects,” Dongwei Li, a neuroscientist at the University of Birmingham and co-author of the paper,The experiment involved 90 participants between the ages of 18 and 25.
After the tPBM treatment, the researchers asked the volunteers to recall the colors and orientations of items displayed to them on a screen. Those who received the long wavelength tPBM treatment showed better recall than the other groups. For example, the full tPBM treatment set recalled roughly four to five objects on average, while the other groups recalled just three to four objects.exactly the laser treatment works.
