Reduction in channel stimulus current under electroconvulsive therapy using multi-channel modes: A numerical simulation study

Traditional bitemporal (BT)-electroconvulsive therapy (ECT) can successfully generate the stimulation required for treatment in the medial temporal lobes (MTLs) [1–3]. However, local overstimulation in the lateral temporal lobes may result in suboptimal outcomes and cognitive risks [4–7]. To reduce the large difference in stimulation strength between the cortical and deep parts of the brain, we propose these innovative multi-channel modes: 1) the bi-channel mode, wherein the BT electrodes and a pair of electrodes on both sides of the coronal suture are used; and 2) the tri-channel mode, wherein the same configuration under the bi-channel mode is followed with the additional placement of another pair of electrodes on both sides of the lambdoid suture.
