Neurofeedback from[ Marcus Cohen age 68 years.
My first neurofeedback session showed high-amplitude waves of excitation sweeping my right hemisphere, while my left hemisphere had little visible activity at all. This corresponded to a state visualization and ideation, not uncommon to me. As I recall I had taken my prescribed ADHD medication that morning, which perhaps exacerbated this right-hemisphere "brain storm". I subsequently discontinued use of this medication.
My next session was several days after a car accident in which I had received a concussion. Activity was low on both sides, resembling a sleep state.
In my next few sessions, we went through training paradigms of both reward and active observation and balancing of local activity. I learned to decrease "brain storms" in favor of regular resting rythms in the right hemisphere, and balance out activity between hemispheres.
What is remarkable are the concurrent subjective changes I felt happening in my conscious and reflective mind with this hemispheric "reconnection". I felt my intuitive "leaps" subject to rational scrutiny and my rational thought processes extended and enriched by intuition.
Oddly enough, my initial emotional reaction was a sadness that such integration had not come earlier in my life. This was, however, quickly replaced with hope to use this powerful tool of neurofeedback training to further balance and condition that powerful engine, my brain.
