On my Professional Partnership with Chuck Davis

by Victoria Ibric, M.D. | September 5th, 2017

Charles Jefferson Davis, affectionately known as Chuck, was born an engineer. At an early age, he spent his time taking things apart to see how they worked. As a boy, he rigged the household phone to talk to people around the world without the help of the phone company. He worked for companies such as NASA’s JPL (Jet Propulsion Laboratory), Lockheed, and others. He was a brilliant engineer that some called the “Black Einstein.” At some point in his life, he decided to focus his efforts on creating something that would make a more direct positive difference in people’s lives. As the inventor of the ROSHI I & II and the pROSHI, he has helped thousands unscramble the anomalies of their brains over the years. This non-drug, non-invasive procedure that he eventually called the Neurodynamic Activator® far exceeded the capabilities of any instrumentation of its kind, and it came along well before its time.

Chuck was a man of many talents. Excited about all things mechanical, Chuck was also a “car guy” who spent considerable time as a race car driver—even racing in the Malibu Classics. He souped up his Mercedes to get better gas mileage and to make it run faster. He was also fascinated by aeronautics and held a pilot’s license.

Chuck was an accomplished musician who worked as lead engineer at Motown in Detroit, Michigan. With extensive experience as a songwriter, music composer and band member, he worked with artists such as the Blackbyrds, Michael Jackson, Bobby Humphries, Diana Ross and Donald Byrd. Chuck played three instruments; the piano, the flute, and the piccolo.

Chuck took great pleasure in helping people, and that opportunity presented itself in abundance with the ROSHI. In fact, the pROSHI was originally created to help a band member. It became his signature invention, helping countless people around the world and creating a devoted user community whose members proudly proclaim themselves as “Roshinis”. He himself derived great satisfaction from watching people’s expression change on their first exposure to the ROSHI.

Chuck enjoyed a 48-year companionship with Audrey Bowen, whose family was engrafted into Chuck’s heart. He forged a long-term business relationship with Dr. Victoria Ibric, who was his first practitioner and strongest supporter. Ultimately his family became the many clients and supporters known as his “ROSHI family.”

Chuck and I met at the Biofeedback Institute of Los Angeles (BILA), where he was working for Hershel Toomim, building components for the Biocomp biofeedback system. We took EEG biofeedback classes together at EEG Spectrum in Encino, with Sue and Siegfried Othmer. At that time, I had no idea who Chuck was. A year later, after becoming more involved in the EEG Biofeedback at BILA, I had the chance to be the first guinea pig for the original ROSHI system. One day, Chuck came in with a diskette that he inserted in the Amiga feedback computer of my NeuroCybernetics system. My experience was more than remarkable. First, the red light from my glasses were stimulating my closed eyes through my eyelids. Soon I observed that the colors were changing, from red to yellow to purple to turquoise, so I asked him why was he changing the colors on me. He laughed and said: “That is your own perception of your own brain wave frequencies changing!” Then I felt a cold tear coming out of my left eye, and suddenly I felt very peaceful. At the end of this experiment, I felt that my body was losing weight and it started to detach from the chair I was sitting in, floating. A moment of anxiety came over me and I told Chuck: “Please get me down now!” All these various feelings during my first ROSHI session made me curious to use it more for myself, and eventually with my clients. That was the beginning of a new friendship between Chuck and me that has lasted a quarter of a century.

I started to use ROSHI with clients who were not responding fast enough to the NeuroCybernetics system and I took very detailed notes of their progress, for research purposes. Many of my clients’ results became case studies presented at various conferences over the years.

After understanding more and more of how ROSHI worked, I presented workshops to many of our colleagues at Winter Brain meetings, ISNR, AAPB, BSC-WABN, ECNS, APA and I also offered internships, from 1998 until the present.

Chuck Davis has forever left his imprint on the world of Neurofeedback. He was brilliant, creative–and occasionally also difficult with some of us. But what would we have done without him? I know this from my own experience and that of other therapists: countless numbers of people have been helped all over the world by his elegant ROSHI-Neurofeedback system, his NeuroDynamic Activator(R)-personal ROSHI trainer. They would have had much more difficult lives, or perhaps might not even have survived, without that intervention. His legacy will live on!
