Reply to comment by LeftOnQuietRoad in Researchers claim a human trial with 90 people has shown a simple laser therapy improves short-term memory by 25%. The treatment, called transcranial photobiomodulation (tPBM), has had claims in previous studies to also improve reaction times, accuracy and attention by lughnasadh

>>I wonder if it just mimics human touch and belonging.

Apparently this works at some specific wavelengths and not others.

That would suggest to me, the mechanism is some transfer of energy from the laser to specific molecules in brain cells. The article mentions this, and suggests those molecules may be in astrocytes, a type of cell that seem to have a role in supplying energy to other cells.

Yeah, or maybe heat and increased blood flow. Insensate vibration could be another way. Kinda cool, though. Hope it pans out in bigger studies.

You are on the right track. Look into PBM in red and NIR frequencies e.g. 620, 679, 760, 810, and 830, and their interaction with Complex 4/ Cytochrome Oxidase C in mitochondrial electron transport chain.

If they can trigger certain cells, then couldn’t technology be used to find a frequency that could harm or affect cancer cells?

I've read about doctors using ultra sound to break up tumors.
