title: A low-noise optically isolated preamplifier for use with extracellular microelectrodes.
abstract: This paper describes in detail the construction of a low-noise optically isolated preamplifier for recording extracellular action potentials from nerve cell bodies and axons. This preamplifier is less prone to pick up noise from extraneous sources of electromagnetic radiation than non-isolated designs.
