LENYO World Ltd.

Developer and Manufacturer of LENYO Devices

This moment is yours…leave everything else to us!

Our goal is to make this modern, side-effect-free method accessible for everyone.

Our Story

Hippocampus-BRT Ltd. was founded in 1993 by Gabor Lednyiczky, who had a vision to integrate all of the different approaches to bio-cybernetics. With the ultimate goal of designing wellness devices that truly help the self-regulation and healing activities of the body, Lednyiczky developed Bioregulation Technology (BRT).

BRT is based on Pulsed Electromagnetic Field (PEMF)  and biofeedback technology. It supports the body’s self-regulation and adaptation processes through the better availability of biologically essential signals.

Hippocampus develops and manufactures the LENYO brand of PEMF-based BRT wellness devices. In addition to these devices, we also develop BRT protocol sofware, application methods and education material. Additionally, we provide detailed training programs on how to use, operate and realize the full potential of BRT technology.

Since the start of the company in 1993, Hippocampus has had many successes – proving that BRT is a valid, scientifically-recognized and widely-used technology. Our products are currently distributed in 43 countries, including both local and international distribution.

With our broad suite of products and our world-wide distribution, the goal of Hippocampus is to make BRT – a modern, side-effect-free, approach to health and wellness – accessible for everyone.
