A nonlinear amplifier for improving signal-to-noise ratio of single-unit recordings.
A simple electronic circuit is described that suppresses the baseline noise and enhances the amplitude of extracellularly recorded action potentials. The circuit is useful for improving the signal-to-noise ratio of single-unit recordings, especially for potentials recorded by chronically electrodes.
