Abstract

The invention discloses an electroencephalogram activity recognition method and device, electronic equipment and a medium. According to the invention, the method comprises the steps: acquiring and preprocessing the electroencephalogram; detecting a high-frequency activity event in the preprocessed electroencephalogram; if the number of the high-frequency activity events is not less than two, obtaining a preliminary screening signal of the high-frequency activity according to the high-frequency activity events; and calculating according to the primary screening signal of the high-frequency activity to obtain a sequential relationship of the high-frequency activity events. According to the technical scheme, whether the intracranial electroencephalogram signals of the user have the high-frequency activity events or not can be automatically detected, and the state category of the user is judged by extracting the time sequence process of each high-frequency activity event and determining the brain region which generates the high-frequency activity earliest. Therefore, the defects that time and labor are wasted in the intracranial electroencephalogram interpretation process and the types and the number of post-processing technologies are limited in the prior art are overcome.

Description

technical field [0001] The present application relates to data processing technology, in particular to a brain electrical activity recognition method, device, electronic device and medium. Background technique [0002] EEG is an important and irreplaceable method to study brain science and brain diseases, including scalp EEG and intracranial EEG. Usually, in order to capture effective information, it is necessary to obtain EEG signals recorded for a long time, and then rely on the doctor's manual visual analysis to identify the EEG activity. However, the high lead count, high sampling rate, and long-term EEG judgment process is complex and heavy, which is not only time-consuming, but also limited by the doctor's experience level, knowledge accumulation and physical state, and the accuracy is difficult to guarantee. . SUMMARY OF THE INVENTION [0003] Embodiments of the present application provide a method, apparatus, electronic device, and medium for identifying brain el...
