The H1 deep transcranial magnetic stimulation coil is FDA-cleared for the treatment of depression. We demonstrate how to utilize the H1 for other conditions, such as auditory hallucinations and PTSD, by moving the helmet to different locations over the subject's skull.

In 1928, a German botanist Emil Heitz observed the moss nuclei with a DNA binding dye. He observed that while some chromatin regions decondense and spread out in the interphase nucleus, others do not. He termed them euchromatin and heterochromatin, respectively. He proposed that the heterochromatin regions reflect a functionally inactive state of the genome. It was later confirmed that heterochromatin is transcriptionally repressed, and euchromatin is transcriptionally active chromatin.
FAQs
Orientation changes how the electromagnetic field is aligned relative to the intended cortical target, so it can influence where stimulation is delivered and the resulting dose. This makes orientation more than a placement detail: two sessions using the same target can differ if the coil is angled differently. Controlling orientation supports consistent neuromodulation across treatment sessions and experiments.
Placement determines the relationship between the coil and the cortical tissue beneath it. Because the changing magnetic field passes through the skull and induces electrical currents in the cortex, shifting the coil can influence both the stimulated brain region and the dose received there. Positioning therefore affects whether stimulation remains directed at the intended cortical target.
Accurate alignment helps researchers connect a stimulation site with the brain function being studied. When the coil remains associated with the intended cortical target, observed effects can be interpreted in relation to that region rather than to an uncertain location. This improves reproducibility and strengthens comparisons among experimental studies that examine TMS-related changes in brain function.
A basic positioning workflow identifies the intended cortical target, places the coil over the corresponding scalp location, and sets its orientation deliberately. The operator then uses the planned placement and alignment consistently during the stimulation protocol. These steps connect the physical coil position with the targeted brain region and help preserve a consistent stimulation dose across the study.
Positioning is important whenever a protocol aims to relate stimulation to a particular cortical region or evaluate a TMS-based intervention. In neuroscience experiments, it supports interpretation of links between stimulation and brain function. In clinical research, consistent placement helps researchers evaluate interventions for neurological and psychiatric conditions while maintaining comparable stimulation across participants or treatment sessions.
Consistent positioning supports reproducible neuromodulation and helps researchers determine whether observed effects correspond to the intended cortical target. It also makes results easier to compare across treatment protocols and experimental studies. By improving the connection between coil placement, stimulated brain region, and dose, careful positioning contributes to evaluating TMS-based interventions and their relationship to brain function.
