Technical Field

The invention relates to the technical field of transcranial direct current stimulation, in particular to a head-mounted device for transcranial direct current stimulation TDCS.

Background

Transcranial Direct Current Stimulation (TDCS) is a non-invasive technology for regulating the activity of cerebral cortical neurons by using constant and low-intensity direct current, and the TDCS consists of an anode and a cathode surface electrodes, and the output of stimulation types is set by control software to act on cerebral cortex by weak polarization direct current. Unlike other non-invasive brain stimulation techniques such as transcranial electrical stimulation and transcranial magnetic stimulation, TDCS does not cause neuronal firing through suprathreshold stimulation, but rather acts by modulating the activity of the neural network. At the neuronal level, the basic mechanism of TDCS regulation of cortical excitability is the change of resting membrane potential hyperpolarization or depolarization depending on the polarity of the stimulus, anodal stimulation generally increases cortical excitability, cathodal stimulation decreases cortical excitability, and membrane polarization is the primary mechanism of action immediately after TDCS stimulation.

However, besides an immediate effect, TDCS also has a post-stimulation effect, if the stimulation duration is long enough, the change in cortical excitability can last up to 1 hour after the end of stimulation. Therefore, its mechanism of action cannot be explained solely by the polarization of neuronal membrane potential. Further studies have shown that TDCS, in addition to altering the polarity of the membrane potential, can also modulate synaptic microenvironment, such as altering the activity of NMDA receptors or GABA, and thus act to modulate synaptic plasticity. The mechanism of postsynaptic effects of TDCS is similar to the long-term facilitation of synapses, and animal studies have shown that a sustained increase in postsynaptic excitatory potential is observed with anodal stimulation of the motor cortex. Modulation of cortical excitability is dependent on the level of membrane polarization upon TDCS stimulation, and the post-effect after stimulation is due primarily to synaptic activity within the cortex.

The applicant found that: when direct current stimulation is carried out on the transcranial position of the head by using the head-mounted equipment, the phenomenon of sliding and falling exists, and after the head-mounted equipment is used for a period of time, the function of quickly disassembling parts is lacked, so that the head-mounted equipment is not convenient enough when needing to be replaced.
