The neurogenesis has been documented from spect scans taken before and after a block of 40 hbot(hyperbarric) sessions. As well, the results of each individuals performance on cognitive testing before and after hbot treatments is a clear

indicator that neurogenesis has occurred. Mark you are too quick to shut people down, I understand you are trying to help, but your negativity can be sometimes extremely discouraging and ultimately incorrect. I understand that you are very knowledgable from years of experience, but you are not an expert. The

information I provided has been clearly documented and can be seen through thorough research that has been scientifically proven by a multitude of experiments and trials. And for the expense of the treatment, yes most the time this is very expensive, yet this does not by any means mean that the treatment does not work.
