However, only about 1% of the electrical current crosses the bony skull into the brain because skull impedance is about 100 times higher than skin impedance. [ 2 ] Aside from effects on the brain, the general physical risks of ECT are similar to those of brief general anesthesia .
[5] [6] [7] These anti-mitotic effects lead to cell death, slowing cancer growth. [ 5 ] [ 6 ] [ 7 ] A TTField-treatment device manufactured by the Israeli company Novocure is approved in the United States and Europe for the treatment of newly diagnosed and recurrent glioblastoma , malignant pleural mesothelioma (MPM), and is undergoing clinical ...
Bioelectromagnetics, also known as bioelectromagnetism, is the study of the interaction between electromagnetic fields and biological entities. Areas of study include electromagnetic fields produced by living cells, tissues or organisms, the effects of man-made sources of electromagnetic fields like mobile phones, and the application of electromagnetic radiation toward therapies for the ...
The electrical stimulation used in HWT differs from other forms of electrical stimulation such as TENS in terms of its waveform; it is intended to emulate the H waveform found in nerve signals, thus permitting the machine to use less power while attaining greater and deeper penetration of its low-frequency current.
Cancer cells and tumors have been known to produce and respond to electrical currents within the body. Cancer cells isolated from brain, prostate, and lung tumors have all been observed to have electrotaxis responses, and it there is evidence suggesting that electrotaxis may play a role in cancer cell metastasis.

The same electrical current is transmitted across both the dispersive electrode and the active electrode, so it is not "neutral". The term "return electrode" is also technically incorrect since alternating electrical currents refer to alternating polarity, a circumstance that results in bidirectional flow across both electrodes in the circuit.
Cranial electrotherapy stimulation (CES) is a form of neurostimulation that delivers a small, pulsed, alternating current via electrodes on the head. [1] CES is used with the intention of treating a variety of conditions such as anxiety , depression and insomnia . [ 1 ]
The vertical axis represents the current intensity in milliamp (mA), while the horizontal axis illustrates the time-course. In transcranial magnetic stimulation (TMS), an electric coil is held above the region of interest on the scalp that uses rapidly changing magnetic fields to induce small electrical currents in the brain. There are two ...
