DEVELOPMENT OF CRYOMAGNETIC SYSTEMS TO CONTROL NEURAL ACTIVITY BY A MAGNETIC FIELD

Resumo

Magnetic field sources are developed and manufactured for experiments in order to activate neuron channels. The designed cryogenic magnetic systems are part of an experimental research stand for remotely controlling neuron expression by static and low-frequency (up to 100 Hz) magnetic fields. The devices are capable of producing an induction field value of ~0.5 T at the liquid nitrogen temperature (77 K); and when working with subcooled liquid nitrogen (70–65 K), the induction field value is above 1 T. The relevance of using the most promising materials—second-generation high temperature superconductors—in the cryomagnetic system is underlined.
