AI Technical Summary

Problems solved by technology

However, these techniques are still insufficient
If the raw EEG report is presented to a physician or technologist, the artifacts often make the EEG report indistinguishable from brain activity such as seizures and artifacts
Despite the use of artifact reduction algorithms, the inability to accurately distinguish between true circadian rhythms and artifacts is a serious shortcoming of current software systems and requires expert evaluation

Abstract

A method (1000) and system (20) for analyzing EEG data is disclosed herein. A processed EEG recording (200) is analyzed to produce a parameter for the EEG. The EEG recording (200) is analyzed to organize a plurality of detections by spike focus, to determine a relative frequency based on a count of detections by spike focus, to average a plurality of detections by spike focus, and the like.

Description

technical field [0001] The present invention generally relates to EEG recordings. More specifically, the invention relates to the analysis of EEG recordings. Background technique [0002] An electroencephalogram (EEG) is a diagnostic tool that measures and records the electrical activity of the human brain in order to assess brain function. A number of electrodes are attached to the person's head and connected to the machine by wires. The machine amplifies the signal and records the electrical activity of the human brain. Electrical activity results from the summation of neural activity across multiple neurons. These neurons generate small voltage fields. The sum of these voltage fields creates an electrical readout that electrodes on the person's head can detect and record. EEG is the superposition of multiple simple signals. In normal adults, the amplitude of the EEG signal is typically in the range of 1 microvolt to 100 microvolts, and when measured using subdural (...
