What is it about?
While existing focality definitions only measure the coverage of the stimulated area in surface units, our novel methodology dimensionlessly quantifies the level of focal stimulation of the target and overstimulation of the surrounding (non-targeted) tissue. This allows to evaluate the suitability of coils to perform focal magnetic stimulation of biological tissues, especially of the brain cortex during TMS session.

Why is it important?
The accurate assessment of the focality allows to improve the effectiveness of therapies based on magnetic stimulation as it avoids the overstimulation of non-targeted tissues. The designed methodology permits to rank different coil designs according to their suitability for a specific target, given parameters such as focal distance and E-field stimulation threshold, among others.
Perspectives
At the Biomagnetics Laboratory, Virginia Commonwealth University, we work for the diffusion of the designed methodology as an instrument for the better design and evaluation of TMS coils, with potential high impact in the industry, as well as in research and clinical settings.
