Abstract

EEG signals with frequencies in the (0 – 5) kHz range were recorded using our new designed instrumentation amplifier with differential input. Measurements were performed in an anechoic chamber to ensure that only brain activity will be recorded. Spontaneous brain activity, and visual evoked potentials were recorded. Raw EEG signals, together with their filtered version, are presented in this paper, in an attempt to compare the results with the EEG signals and evoked potentials already known from the scientific literature..

Keywords
