The history of continuous EEG monitoring

The history of electroencephalography (EEG) began in the late 1800s and has increasingly led to clinical, experimental, and computational studies that have enabled the discovery, understanding, recognition, diagnosis, and treatment of a great number of neurophysiological abnormalities and critical illnesses of the brain and spinal cord. Currently, EEGs are often continuously recorded mostly using scalp or cortical electrodes with enough digital EEG memory to store extended recordings of several hours. Modern EEG machines are further equipped with fully computerized signal processing systems allowing rapid and multidimensional analyses that present many challenges to the managing physicians.
