Spike Sorting at the Electrode: Neural Ensemble Recording from the Flying Bat

Abstract : Our laboratory has been working towards completion of an adaptive clustering spike-sorting circuit and the acquisition of bat vocalizations from a flying bat. In this summary for the project, we show some basic operation of the spike-sorting chip and discuss issues for further development. We have successfully flown a radio telemetry microphone on a bat and recorded good signals for the beginning of a new series of bat behavioral experiments.
