A recent research from the University of Birmingham in the UK and the Beijing Normal University in China concluded that it's possible to improve short term memory with 1064nm LED-based transcranial photobiomodulation (PBM) in normal adults by around 10%.
This study on short term memory from December 2022 compared a single 12-minute treatment with a 1064nm and an 852nm laser light to the left or right side of the forehead. Participants were asked to quickly and accurately tell if the orientation or color of objects displayed on a screen in the cued half of their vision had changed after a short delay.
This research showed that light therapy at 1064nm can improve short term memory, as evidenced by increased occipital-parietal activity in the brain as measured by event-related potentials.
According to the data from the EEG monitoring, the study sample's low and high-performing subgroups responded to the 1064nm stimulation with significant short term memory improvements over those who had received the treatments at a wavelength of 852nm.
Quietmind Foundation's Experiments
These research findings back up the results of experiments on short term memory done at Quietmind Foundation from 2012 to 2020, which looked at the effects of a 6-minute use of 1068nm LED-based brain and eye stimulation.
From a group of 500 volunteers, 85% reported an increase in overall sensation of increased brightness, the richness of color, discriminative acuity, and depth of field. Subjects responded to viewing a natural scene just outside the clinic offices before and then immediately following the stimulation session, which included grass, bushes, and trees in the nearfield 3-5m and at a distance (10-20m).
These trials on short term memory were conducted at all times during the day and over all seasons. Therefore, these results are consistent with the point made in the present study as to the neurophysiological mechanism being an increased amount of visual data being processed (p.3).
The present research wisely considered the effect of tissue heating by the higher 1064nm light wavelength and so they equalized the light delivery from both wavelengths of light delivered equally to the scalp tissue. According to this study, the behavioral and electrophysiological findings with 1064nm transcranial photobiomodulation (tPBM) were not explained by heating. While the electrophysiological measures produced marginal significance, the subjects' own perception of the difference between the two treatment modalities was no more significant than chance (p.5).
Neuronic and Quietmind Foundation are now collaborating with one of the study's authors, Professor Liu from The University of Texas at Arlington, to study the biological impact of 1070 nm LED-based transcranial photobiomodulation (tPBM) on both normal and clinical populations.
Did you know that the Neuradiant 1070 is the first and only 1070nm self-administered transcranial photobiomodulation device with 4-quadrant control on the market?
Neuronic is already using the 1070nm wavelength range spoken about in these studies about short term memory, which represents the next generation of transcranial photobiomodulation (PBM) technology, based on the QMF-BRI research unit that can safely and reliably offer home-based, self-administered, and affordable photobiomodulation (PBM) treatment. This technology offers real hope to people dealing with a wide range of neurodegenerative, chronic pain, and neuropsychiatric disorders.
