Transcranial magnetic stimulation coils

Book section · February 10, 2021 Many different types of TMS coils have been proposed and implemented, but all share certain common features. The induced electric field is always maximum in the superficial parts of the brain, nearest the coil, and attenuates toward the center of the head. ... Full text Cite

TMS pulse waveform and direction

Book section · February 10, 2021 The pulse waveform and current direction contribute to the specific effects of transcranial magnetic stimulation (TMS). For single pulse TMS these factors have been shown to influence, for example, motor threshold and recruitment curve, motor-evoked potent ... Full text Cite

Transcranial magnetic stimulators

Book section · February 10, 2021 Transcranial magnetic stimulators are used for clinical diagnostic and therapeutic applications as well as in support of research. Consequently, a number of stimulator types and design variations have been developed to serve these purposes each having uniq ... Full text Cite

Transcranial electrical stimulation devices

Book section · February 10, 2021 Transcranial electrical stimulation (tES) devices apply electrical waveforms through electrodes placed on the scalp to modulate brain function. This chapter describes the principles, types, and components of tES devices as well as practical considerations ... Full text Cite

Physics and biophysics fundamentals of transcranial stimulation

Book section · February 10, 2021 Transcranial stimulation induces or modulates neural activity in the brain through basic physical and biophysical processes. Transcranial electrical stimulation and transcranial magnetic stimulation impose an exogenous electric field in the brain that is d ... Full text Cite

Transcranial Magnetic Stimulation: Principles and Applications

Book section · January 1, 2020 Transcranial magnetic stimulation (TMS) is a noninvasive method for focal brain stimulation, with applications in research, diagnostics, and treatment. In basic research, TMS can help establish a causal link between a brain circuit and a behavior. Clinical ... Full text Cite
