In the rapidly evolving field of neuroscience, non-invasive brain stimulation is a new hope for understanding and treating a myriad of neurological and psychiatric conditions without surgical intervention or implants. Researchers, led by Friedhelm Hummel, who holds the Defitchech Chair of Clinical Neuroengineering at EPFL’s School of Life Sciences, and postdoc Pierre Vassiliadis, are pioneering a new approach in the field, opening frontiers in treating conditions like addiction and depression.
Vassiliadis, lead author of the paper, a medical doctor with a joint PhD, describes tTIS as using two pairs of electrodes attached to the scalp to apply weak electrical fields inside the brain. “Up until now, we couldn’t specifically target these regions with non-invasive techniques, as the low-level electrical fields would stimulate all the regions between the skull and the deeper zones—rendering any treatments ineffective.
