tES Electrodes, Round

Round electrodes are most commonly used in High Definition tES applications as their small, round design allows for better control over the distribution and direction of current. By restricting the electrical current to flow between such a small surface area helps clinicians and researchers shape the electric field more accurately than standard electrode setups. This design highly concentrates the electric field directly beneath the target site rather than allowing it to spread widely across the scalp and cortex, making stimulation more precise, accurate and stronger for the intended brain region.
