Transcranial magnetic stimulation is a method to noninvasively stimulate neurons in the brain and induce immediate or long term changes in activity. Stimulation is mediated by electromagnetic induction of weak electric current in neurons using an electromagnetic coil over the head.
In this pilot study, the authors detected specific brain regions that can be precisely targeted with transcranial magnetic stimulation to influence heart rate. The heart–brain coupling might serve as a readout to identify optimal individualized transcranial magnetic stimulation targets for depression.
Voetterl and colleagues examined the application of ‘Brainmarker-I’, an age- and sex-normalized electroencephalogram measure of individual alpha peak frequency, on predicting remission to therapeutic noninvasive neuromodulation protocols (repetitive transcranial magnetic stimulation and electroconvulsive therapy).
Fusion of ferritin with a transient receptor potential V1 (TRPV1) channel produces an ion channel that can be selectively targetted to specific neuronal populations and opened by application of a magnetic field.
