From a brief look at the citations, there doesn't seem to be any scientific basis behind it. The cited patents are either from the same inventor, describe optical manipulation of the nervous system or are related to systems where EM human exposure is relevant (e.g. MRI and X-ray machines). The one paper cited talks about a threshold voltage required to excite neurons but nothing about intensity levels relevant for this patent. I might be wrong as I didn't do an indepth search of the cited patents made by the same inventor.
