Transcranial magnetic stimulation system design and fabrication

Background. Transcranial magnetic stimulation (TMS) systems are orders of magnitude more expensive than electrical stimulation ones. This limits the number of neuroscience experiments using them for studying the effects of E-fields on the brain.

Objective. The objective of this project is to create easly replicable blueprints for a low-cost TMS stimulation system for in-vitro and in-vivo experiments to accelerate its use in neuroscience experiments and our understanding of these technologies.

Approach. We have designed and fabricated low-cost biphasic stimulators. Furthermore, we have leveraged various algorthms to design coils hat both have improved targetting and energy efficiency.  

Anticipated significance. A less costly option for TMS could lead to more neuroscience experiments that use it, and enable a better understanding of its effects.
