AN ELECTRONIC INTERFACE FOR NEURAL ACTIVITY RECORDING AND STIMULATION

Abstract

A portable neural activity acquisition and stimulation system by means of tfLIFE implantable electrodes has been realized. The detecting circuit provides: a selective filtering made up of a 4th order high pass Multiple Feedback filter (f_ -3dB = 1.1kHz) and a 4th order low pass Multiple Feedback filter (f_ -3dB = 2kHz), a variable gain (24dB - 44dB) and a 16 bit analog to digital conversion. The stimulator allows to generate specific electrical signals through a digital-to-analog converter while stimulation parameters as frequency, duration and intensity are controlled by a digital microcontroller. Simulation results and first experimental results of the interface demonstrate how neural signals of a few of microvolts can be filtered, programmable amplified and digitalized without distortion.
