Curved sensor net used to record electrical signals of the brain, Europe, 1990-1998
Sixty-four electrodes form this geodesic sensor net, which picks up weak electrical signals from the brain. This net was used at the Cognitive Development Unit at University College London to investigate how young babies recognise faces. Recordings of the electrical signals of the brain are known as electroencephalograms (EEGs).
