Experts at the University of Birmingham and Beijing Normal University have found that laser light therapy may be effective in enhancing short-term memory.
According to the study, released in the journal Science Advances, experiments were conducted on 90 participants in young adulthood.
The participants were administered a laser light to the right prefrontal cortex at wavelengths measuring 1,064 nm. Other participants received shorter wavelengths.
Electroencephalograms, as well as other data, were examined by the research team for a better understanding as to any changes in brain activity.
“Transcranial photobiomodulation (tPBM) is a safe and noninvasive intervention that has shown promise for improving cognitive performance,” according to researchers.
“In this study, we found that 1064-nm tPBM applied to the right prefrontal cortex (PFC) improves visual working memory capacity and increases occipitoparietal contralateral delay activity (CDA).”
“Our findings provide converging evidence that 1064-nm tPBM applied to the right PFC can improve WM capacity.”
