Transcranial magnetic stimulation device
This video describes a prototype of a transcranial magnetic stimulation device designed by Ben Krasnow. He explains:
Transcranial Magnetic Stimulation (TMS) is a technique to stimulate brain tissue directly through the skull. It works by sending a very high current pulse through a coil that is located on the subject’s scalp. The fast-rising edge of the pulse induces a current in the brain tissue, causing neuron stimulation.
This is Part I of the project in which constructs a butterfly coil and related circuitry. Here’s a link to the datasheet for the SCR he refers to.
In this video Ben demonstrates the actual use of this device. He’s switched to using a single coil rather than the butterfly coil described in the first video. The voltage involved here is ~1700 volts! This qualifies as a “Dangerous Prototype” to us!
