title: [Biopotential amplifier with nonlinear volt-ampere characteristics for recording low-amplitude pulses].
abstract: An amplifier with non-linear volt-ampere characteristics for recording low-amplitude nerve pulse activity is offered. It permits recording impulses with an amplitude exceeding the noise by 3-5 microV and afferent impulse activity of rat taste nerves.
