#64: Balint Varkuti – Making Use of Side-Effects: Redefining Brain Computer Interfaces with Ceregate

Today, we have the pleasure of speaking with Dr. Bálint Várkuti, a distinguished expert in the field of neuromodulation. Dr. Várkuti is the founder and CEO of CereGate, a pioneering company developing brain-computer interface technologies—referred to as computer-brain interface technologies—that aim to enhance neuromodulation therapies.

Before founding CereGate, Dr. Várkuti made significant contributions to image-guided DBS programming solutions at Brainlab. With over a decade of experience in neurotechnology and the medical device industry, his work focuses on designing innovative interfaces between technology and the human brain to improve patient outcomes.

For those familiar with DBS, you’ll understand the nuances here: when stimulation of the super-dynamic nucleus in DBS is set too high, patients often experience a tingling or irritating sensation due to overstimulation of sensory fibers. Typically, this side effect is avoided. However, Dr. Várkuti had a groundbreaking insight: This sensation represented a channel of information with the brain – and one could make use of it!

In a nutshell, CereGate leverages these overlooked pathways, using them in a patterned and complex way to transmit information that the brain can decode. This approach opens up new possibilities for interfacing with the brain, which we find truly fascinating: This concept that CereGate is exploring might just be the start of a much larger field of innovation.
