Human, Animal Extracellular Neural Recordings

The Neuro Amp EX includes an amplifier unit and shielded headstage whose amplification and filtering settings are controlled from within Chart or Scope. This enables users to manage the acquisition, recording and analysis of neural signals from a single software interface. The new hardware can be used with commercially available high-impedance metal microelectrodes. Due to the noise associated with these electrodes and the high-gain required for recording nerve signals, the Neuro Amp EX Headstage provides preamplification gain of 100× and a 10 Hz filter. The result is a slim-line headstage with ultra-low noise and signal to noise ratio. The Neuro Amp EX also gives the user further amplification and filtering options (100Hz –5kHz), including high-pass, notch and mains filters. The Neuro Amp EX is certified safe for human as well as animal use as both the headstage and amplifier are fully isolated from the mains circuitry. Human applications include multi-unit and single-unit recordings from peripheral nerves (for example, sympathetic nerve recordings), and single unit recordings from muscle fibers. Typical animal applications include whole nerve and split-fiber nerve recordings, as well as microelectrode recordings from single neurons in the brain, spinal cord or ganglia.
