Electrocorticogram

Electrocorticography (EEG, ECG, ECoG) is a method for recording the bioelectric potentials of the cerebral cortex (biopotentials), based on the use of multichannel systems with multiple output electrodes located on the surface of the head, and subsequent computer processing of the obtained data.

Electrocorticography (ECoG, electroencephalography, EEG, ECG) - registration of brain biopotentials using a lead from the surface of the skull.

EEG is a diagnostic method that allows you to assess the functional state of the cerebral cortex. This method is widely used in medicine to diagnose various diseases such as epilepsy, depression, schizophrenia and other mental disorders.

In addition, EEG is used in scientific research to study the mechanisms of the brain and its interaction with the environment.

To record EEG, a special device is used - an electroencephalograph. It consists of many electrodes that are placed on the surface of the patient's head. Each electrode records the electrical activity of the brain in a specific area.

The obtained data is processed using special programs that make it possible to analyze changes in biopotentials in various frequency ranges. This allows us to identify different types of brain activity, such as alpha, beta, theta and delta rhythms, as well as pathological changes associated with various diseases.

Thus, electrocorticographic diagnostics is an important tool in medicine and scientific research, allowing one to obtain information about the functional state of the cerebral cortex and identify various disorders of its functioning.

For a long time, acoustic speech analysis has focused on how to separate speech sounds from environmental noise. These signals were found to vary in spectrum and shape. Most speech recognition systems are based on technologies such as linear prediction, wavelet analysis or resonant filters, and others that operate
