Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of neural signal alignment, and in particular to a method for aligning unhealthy neural signals to healthy neural signals. Background Art
[0002] Currently, neural signal acquisition is typically performed using both invasive and non-invasive techniques. However, the target's health status is not considered during neural signal acquisition. When an organism is in an unhealthy state, the central nervous system's response slows, which can directly lead to delayed movement and action. Fever can also cause dilation of brain blood vessels and increase cerebral blood flow. Numerous studies have shown that the brain can directly regulate neural activity through the heartbeat. When the heart pumps blood, brain blood vessels dilate, changing the distance from the electrode to the neuron and the resistance, thereby reducing the measured signal amplitude and lengthening its width. Therefore, the target's health status will affect the response time of its neural signals, the waveform amplitude / width, and other factors, and the acquired signals may contain noise. Therefore, a method to align unhealthy neural signals with healthy neural signals is urgently needed to address this issue. Summary of the Invention
