Abstract

The invention discloses a system for detecting and positioning a brain stimulation target point. The system comprises an induction unit, a signal collecting and recording unit, a signal analyzing and processing unit and an information merging unit. The induction unit is used for inducing an examined person to move autonomously and at least one brain function state in the feeling or emotion so that the brain of the examined person can generate a brain physiological signal. The signal collecting and recording unit is arranged on the brain of the examined person and comprises a physiological signal sensor sensing the brain physiological signal, a front-end collector electrically connected with the physiological signal sensor and used for recording collected data, a microcontroller receiving the brain physiological signal output by the front-end collector, and a signal transmission communication module electrically connected with the microcontroller and used for outputting the signal. The signal analyzing and processing unit receives the brain physiological signal, processes and analyzes the brain physiological signal and outputs a quantitative result of the most obvious responding position (the target point) of the brain physiological signal. The information merging unit is used for conducting image merging of the quantitative result and an image of the brain of the examined person through a display module. According to the scheme, the target point position in deep brain stimulation can be effectively and quantitatively positioned.

Description

technical field [0001] The invention relates to a system and method for locating deep brain stimulation targets and electrode navigation. Background technique [0002] At present, imaging methods based on stereotaxic methods are usually used for target positioning. However, due to image scanning errors, there is an error of up to 3 cm in methods that rely solely on imaging methods for positioning. Therefore, a small number of neuroelectrophysiological microelectrode recording methods are used to detect and locate the target. However, none of these methods can truly, quantitatively, and accurately reflect the positional relationship between the final implanted stimulating electrode and the target. [0003] According to research findings, deep brain nuclei or neuron clusters have specific functions, and physiological signals (including bioelectrical signals, biochemical signals, etc.) from these tissue structures can reflect the functional state of the brain in real time. Fo...
