Source: Laboratories of Jonas T. Kaplan and Sarah I. Gimbel—University of Southern California Transcranial Magnetic Stimulation (TMS) is a non-invasive brain stimulation technique that involves passing current through an insulated coil placed against the scalp. A brief magnetic field is created by current in the coil, and because of the physical process of induction, this leads to a current in the nearby neural tissue. Depending on the duration, frequency, and magnitude of these magnetic...

Hair cells are the sensory receptors of the auditory system—they transduce mechanical sound waves into electrical energy that the nervous system can understand. Hair cells are located in the organ of Corti within the cochlea of the inner ear, between the basilar and tectorial membranes. The actual sensory receptors are called inner hair cells. The outer hair cells serve other functions, such as sound amplification in the cochlea, and are not discussed in detail here. Hair cells are named after...

FAQs
Dense or long hair increases the physical gap between the coil and scalp. Because TMS relies on a rapidly changing magnetic field to induce electrical currents in superficial cortical tissue, that added separation becomes a delivery concern. Researchers therefore need to account for hair-related distance when seeking stable stimulation intensity and reliable engagement of the intended cortical area.
Coil orientation determines how the magnetic field is positioned relative to the targeted cortex, while scalp contact helps maintain a consistent coil-to-head relationship. With thick hair, both can be harder to standardize. Careful alignment and contact are therefore important setup factors because they support accurate targeting and reduce variation in stimulation delivered across sessions or participants.
Hair management matters scientifically because differences in coil placement or distance can introduce unwanted variation between measurements. If one session uses firm compression and another leaves more hair beneath the coil, the stimulation conditions may not be equivalent. Standardizing these features strengthens reproducibility when studying brain function, plasticity, or responses associated with neurological and psychiatric conditions.
Parting separates hair from the intended coil path, compression reduces the hair-related space between coil and scalp, and repositioning helps recover consistent placement when contact remains difficult. These strategies address different practical problems, so researchers may select or combine them according to whether the main concern is distance, contact, or targeting.
Before stimulation, the operator can identify the target, part or compress the hair, and place the coil with attention to orientation and scalp contact. If the setup is unstable, repositioning may be necessary. Applying the same sequence across sessions helps preserve comparable stimulation conditions and supports more interpretable results.
It is relevant wherever TMS is used to examine brain function or plasticity, and in studies involving neurological or psychiatric conditions. In these settings, hair-related changes in coil distance, orientation, or contact can become experimental variables. Managing them helps researchers interpret stimulation-related outcomes as reflecting the intended protocol rather than inconsistent physical setup.
