TRANSCRANIAL MAGNETIC STIMULATION Meaning and
Definition
-
Transcranial magnetic stimulation (TMS) refers to a non-invasive medical procedure that involves the use of magnetic fields to stimulate specific regions of the brain. TMS is utilized for diagnostic and therapeutic purposes, particularly in the field of neurology and psychiatry. By using electromagnetic coils that are placed on the scalp, TMS generates magnetic fields that are capable of penetrating the skull and inducing electrical currents within the brain.
In the context of diagnostic applications, TMS can be used to map brain function and connectivity. Through TMS, neural activity can be assessed, providing valuable insights into brain disorders such as strokes or tumors. Furthermore, TMS can also serve as a means of stimulating the brain during neurosurgical procedures to prevent damage to critical regions.
Therapeutically, TMS has shown promise in the treatment of various neurological and psychiatric conditions, including depression, anxiety, and chronic pain. Repetitive transcranial magnetic stimulation (rTMS) is a commonly employed technique whereby repeated magnetic pulses are applied to specific brain areas over multiple sessions. This stimulation can modulate neural activity and potentially alleviate symptoms associated with these conditions.
While TMS has demonstrated effectiveness, it is a relatively new medical technique and ongoing research is still being conducted to examine its full range of applications and potential side-effects. Overall, transcranial magnetic stimulation offers a non-invasive approach to modulating brain activity, serving as a valuable tool for both diagnosis and treatment in the field of neuroscience.
