I experimented with this technology on myself. I've also discussed/debated with Mark previously on this form. I used NIR lasers pointed at my brain stem and cerebellum from varying angles. I tried to mimic power densities discussed in scientific literature. After 10 sessions my results were ambigius, and not enough to conirm if infact results were realized. What I can report is that it was safe to experiment at the risk of injury is little to nonexistent.

After all my research, i'm still uncertain about the efficacy of skull penetration in a human brain, especially if youre trying to get deeper than brain surface. There's lots of positive research if you research 'transcranial laser therapy'. However there's lots of research that counters these points. Summary, it's safe to experiment.

There's also a back door into the brain using NIR laser therapy. It's extremely low level, much slower, and even safer, and cheap. Look into Intranasal light therapy. There's a product made by -Vielight ($200). It looks like an iPod and uses a small LED that inserts into your nose. The idea is that it difuses blood capillaries from the nasal cavity into the brain. This redirection of blood flow travels by gradients, and sends blood to brain regions with lesser amounts of blood flow. This causes nutrient transport, ATP production, new blood cell generation, and thus reparation. There's lots of consumer reviews on this product. So if you're discouraged by the uncertainty of direct skull penetration, try the back door through the nose.

Good luck.
