Summary

Transcranial direct current stimulation(tDCS) is a non-invasive Neuromodulation method.The weak direct current produced by tDCS can be transmitted through the skull and induce biphase, polarization-related changes in the cortex. Related clinical studies have found that tDCS has a corresponding therapeutic effect on neurological and psychiatric diseases such as stroke rehabilitation, depression, pain, epilepsy, etc.

Stereotactic electroencephalography(sEEG) implants a set of deep electrodes into the brain that use stereotactic localization to detect electrical activity, locate epileptic foci and functional areas, and detect changes in electrical fields caused by tDCS in the deep brain. This direct measurement technology will provide validation and optimization for the electric field simulation method based on finite element analysis (FEM), also complement the latest indirect current density intensity measurement technology based on MRI phase measurement, providing support for the targeting and personalized treatment of tDCS technology.

In order to achieve this goal and study the mechanism and function of tDCS better , this project aims to realize the clinical use of sEEG to measure the electric field information generated by tDCS in the human brain in vivo.

Conditions

DEVICE

transcranial direct current stimulation

Depending on the location of sEEG electrode implanted in the patient's head, the tDCS electrode (5 cm×7 cm each) was placed on occipital-frontal lobe or bilateral temporal lobe. Current intensity: 2 mA and 4 mA, Stimulus time: 3 min (each stimulus session).
