Retaining cap used for acquiring brain signals in photoelectric combined mode and applied to transcranial magnetic stimulation

Abstract

The invention provides a retaining cap used for acquiring brain signals in photoelectric combined mode and applied to transcranial magnetic stimulation. The retaining cap comprises a flexible net-shaped retaining cap body composed of flexible net belts and capable of covering the scalp, vertically-through penetrating holes are formed in all nodes of the flexible net-shaped retaining cap body respectively, a brain electricity electrode hollow sleeve and a near infrared probe hollow sleeve can be rotationally inserted into the penetrating holes, a brain electricity electrode is placed in the brain electricity electrode hollow sleeve, and a near infrared probe is placed in the brain electricity electrode hollow sleeve. The brain electricity electrode and the near infrared probe are distributed in the flexible net-shaped retaining cap body in the mode that the portions, along the two ends of a flexible net belt on a meridian, of each brain electricity electrode is each provided with one near infrared probe at equal intervals, one of the two near infrared probes at the two ends of each brain electricity electrode is a near infrared probe for emitting infrared rays, and the other of the two near infrared probes is a near infrared probe for receiving the infrared rays. Scalp pulling-out is convenient, the height of the retaining cap is reduced, and the acquisition quality of near infrared signals is improved. The retaining cap can be effectively applied to transcranial magnetic stimulation research.

Description

technical field [0001] The invention relates to a headgear for collecting brain signals. In particular, it relates to a headgear for combined photoelectric collection of brain signals applied to transcranial magnetic stimulation. Background technique [0002] Transcranial magnetic stimulation (TMS) technology is a technical means of modern brain science research, which is painless and non-invasive. The principle is that a magnetic field is generated by a magnetic stimulation coil and passes through the brain relatively unhindered to induce depolarization of the neuronal membrane potential. Currently, TMS technology is widely used in brain cognition and brain network research. [0003] TMS combined with scalp electroencephalography (EEG) has been widely used in the study of brain connectivity and brain function. TMS activates local cortical tissue, while EEG has high time resolution when recording local cortical nerve conduction. Combining the two can analyze the changes o...
