Description

Technical Field

[0001] The present disclosure relates to the field of electrode technology, and in particular to a high-precision electrode for transcranial nerve stimulation. Background Art

[0002] Cranial microcurrent stimulation (CES) is a completely different treatment method from traditional drug therapy and electroconvulsive therapy. It stimulates the brain with low-intensity microcurrents, changes abnormal brain waves in the patient's brain, and prompts the brain to secrete a series of neurotransmitters and hormones that are closely related to anxiety, depression, insomnia and other diseases, thereby achieving the treatment of these diseases. Compared with drug therapy, this treatment method has no side effects and stable efficacy, so it has been widely used in Europe, the United States and other countries as a safe and effective treatment for anxiety, depression, insomnia and related diseases.

[0003] Transcranial direct current stimulation (tDCS) is a non-invasive technique that uses constant, low-intensity direct current (1-2 mA) to regulate the activity of neurons in the cerebral cortex. tDCS has two different electrodes and their power supply battery devices, plus a control software to set the output of the stimulation type. There are three types of stimulation methods, namely, anodal stimulation, cathodal stimulation, and sham stimulation. Anodal stimulation usually enhances the excitability of neurons at the stimulation site, while cathodal stimulation reduces the excitability of neurons at the stimulation site. Sham stimulation is mostly used as a control stimulation. Unlike stimulation techniques such as transcranial electrical stimulation and transcranial magnetic stimulation, tDCS does not cause neuronal discharges through suprathreshold stimulation, but works by regulating the activity of neural networks. At the neuronal level, the basic mechanism of tDCS regulation of cortical excitability is to cause changes in resting membrane potential hyperpolarization or depolarization depending on the polarity of the stimulus. Anodal stimulation usually increases the excitability of the cortex, while cathodal stimulation reduces the excitability of the cortex. Membrane polarization is the main mechanism of tDCS action immediately after stimulation.

[0004] However, in addition to the immediate effect, tDCS also has a post-stimulation effect. If the stimulation time lasts long enough, the change in cortical excitability can last up to 1 hour after the stimulation ends. Therefore, its mechanism of action cannot be explained solely by the polarization of neuronal membrane potential. Further studies have confirmed that in addition to changing the polarity of membrane potential, tDCS can also regulate the microenvironment of synapses, such as changing the activity of NMDA receptors or GABA, thereby regulating synaptic plasticity. The after-effect mechanism of tDCS is similar to the long-term facilitation of synapses. Animal studies have found that a sustained increase in postsynaptic excitatory potentials can be observed when anodal stimulation is applied to the motor cortex. The regulation of cortical excitability depends on the level of membrane polarization during tDCS stimulation, and the after-effect after the stimulation ends is mainly due to the activity of synapses in the cortex.

[0005] tDCS can also modulate the excitability of remote cortical and subcortical areas. tDCS anodal stimulation of the premotor cortex can affect changes in the excitability of connected remote cortical areas. Stimulation of the left hemisphere M1 area not only affects the corticospinal circuits involved in generating motor evoked potentials, but also modulates transcallosal inhibition of the contralateral hemisphere through inhibitory interneurons.

[0006] However, the existing stimulation electrodes have a complex structure, are inconvenient for patients to use, and the stimulation effect is not very obvious. Utility Model Content
