With the accelerated pace of modern life, sleep disorders have become a common problem that plagues many people. In order to meet this challenge, scientists have developed a variety of treatment methods, among which the transcranial stimulation sleep aid device has attracted widespread attention for its non-invasive, safe and effective characteristics. So, how does this device work?
The transcranial stimulation sleep aid device, also known as the transcranial magnetic stimulator (TMS), is a neuromodulation technology based on the principle of electromagnetic induction. Its working principle mainly relies on Faraday's law of electromagnetic induction, that is, when the magnetic field changes, an induced current will be generated in the conductor. In TMS, this conductor is the human brain tissue.
Specifically, the TMS device contains a powerful magnetic field coil. When the device is turned on, the coil will discharge rapidly to generate a pulsed magnetic field. This magnetic field can penetrate the skull and directly act on specific areas of the cerebral cortex. When the brain tissue is exposed to this time-varying magnetic field, weak induced currents or eddy currents will be generated inside it. These induced currents further change the transmembrane potential of the cell membrane, depolarizing the cell membrane, thereby activating the relevant neural tissue.
This non-invasive stimulation of the brain by TMS can regulate the excitability of brain neurons and improve neurological function. Especially in the brain areas related to sleep, TMS can directly affect the secretion of neurotransmitters and regulate brain rhythms, thereby achieving the purpose of improving sleep quality.
When used in the treatment of sleep disorders, TMS devices usually select specific stimulation sites and stimulation parameters. For example, for insomnia patients, the left and right dorsolateral areas of the prefrontal lobe can be selected as stimulation sites, and low-frequency stimulation can be used to reduce the excitability of the cerebral cortex and help patients enter a deep sleep state faster.
In addition, TMS devices are also highly flexible and adjustable. Doctors can adjust parameters such as stimulation sites, stimulation frequency, and stimulation intensity according to the specific conditions and treatment effects of the patients to achieve the best treatment effect.
In general, the transcranial stimulation sleep aid device directly acts on the cerebral cortex through the principle of electromagnetic induction, regulates the excitability of brain neurons, and thus improves sleep quality. Its non-invasive, safe and effective characteristics provide a new treatment option for patients with sleep disorders. With the continuous advancement and improvement of technology, it is believed that TMS devices will bring good news to more people with insomnia in the future.
