Description
Technical field
The invention belongs to Non-destructive Testing Technique, particularly a kind of integrated ultrasound stimulation and eeg signal acquisition probe.
Background technology
Low-intensity TCD,transcranial Doppler cranial nerve stimulating technology is a kind of new brain stimulation method growing up in recent years, there is not damaged, high spatial resolution, the high feature that stimulates the degree of depth, ultrasonic wave is a kind of mechanical pressure ripple, gains the name to be greater than people's earshot (2KHz-20KHz). Ultrasonic wave has the good characteristic that penetrates solid structure, comprises Bone and soft tissue, and therefore ultrasonic wave is widely used in medical treatment. Ultrasonicly can be sent to tissue with the form of impulse wave or continuous wave, cause the physiological change of tissue by fuel factor or mechanical effect. Thereby low-intensity TCD,transcranial Doppler stimulates a kind of technological means that refers generally to penetrate complete large bones of cerebral cranium and reach with low-strength focusing ultrasonic the modulation to nervous function, it has security, the permanent side effect of nothing, controllability, nothing wound, invertibity, neither destroy brain tissue or nerve, also do not affect other new treatment from now on. Eeg recording can, to the explanation of the variation quantitative of brain neurological motion before and after stimulating, be a kind of method of evaluating effect of stimulation with analyzing. But research is in the past mostly that ultrasound stimulation is separated with EEG signals with patent, the variation of EEG signals when monitoring ultrasound stimulation that can not be real-time.
