The worst thing that can happen, I believe (based on experimenting with infrared on my brain for the last 4 years with no side effects) that instead of stimulation, you will get the opposite, slowing down of potentials. By the time a person with a relatively stable mind notices what's going on, they stop and the brain will probably jump back after a while. So for an experiment, it should be safe. A lot safer than doing psychedelics for example.
This of course means that the time used per day is reasonable. Probably along the lines of minutes, not hours a day.
re: side effects
I did have a period of 4-6 months were I experienced great mood shifts and childhood flashbacks and associated feelings (like rage or fear or sadness). If you are in the midst of something important in the external world, like upcoming exams or a demanding job where you can't take sick leave, proceed extra carefully.
The same may happen with ultrasound. At least in my case the end result was very positive. It helped with Asperger's syndrome, depression and anxiety. It changed me completely as a person. I still have my problems but much less : )
