Abstract: | This article describes the design and preliminary evaluation of a small-sized and low energy consumption wearable wireless
telemetry system for the recording of extracellular neuronal activity, with the possibility of selecting one of four channels.
The system comprises four radio frequency (RF) transceivers, three microcontrollers, and a digital amplifier and filter. This
constitutes an innovative distributed processing approach. Gain, cutoff frequencies, and channel selection are remotely adjusted.
Digital data transmission is used for both the bioelectrical signals and the control commands. This feature offers superior
immunity to external RF interference. Real-time viewing of the acquired data allows the researcher to select only relevant
data for storage. Simultaneous recordings of neuronal activity from the striatum of a freely moving rat, both with the wireless
device and with a wired data acquisition system, are shown. |
