Modalities

Non-contact EEG method utilizing capacitive sensors, enhancing user comfort and ease of setup.

Invasive recording of brain activity from the cortical surface.

A graphic record of the variation with time of voltages taken from electrodes on the scalp, whose positions are specified according to a standard system.

A graphic record of the variation with time of voltages produced by the electrical activity of muscle fibers, recorded via electrodes placed on the skin or inserted into the muscle.

Technique for recording electrical activity in peripheral nerves, complementing central modalities.

A graphic record of the variation with time of voltages taken from electrodes placed onto or deeply inserted into the brain to directly record electrical activities of the brain through sensors.

A topographic or graphic record, as a function of time, of magnetic fields associated with the electrical activity of the brain.

A numerically intensive, computational analysis of EEG data using mathematical algorithms (such as Fourier or wavelet analysis) to quantify brain activity patterns, providing detailed brain mapping and diagnostic insights beyond traditional visual EEG interpretation.

Signal acquisition from individual neurons via microelectrodes.
