Spectral properties of neuronal pulse interval modulation

John J. Varghese, Kristian J. Weegink, P. A. Bellette, Andrew P. Bradley

ICASSP 2015accepted

We determine the power spectrum of an ideal neuron which encodes information using a pulse interval modulation scheme in continuous time. We develop this by considering the rigorous derivation of the Digital Pulse Interval Modulation (DPIM) coding scheme spectra of L. Vangelista et al. in the limit…

Spikes from compound action potentials in simulated microelectrode recordings

Kristian J. Weegink, John J. Varghese, Andrew P. Bradley

ICASSP 2015accepted

In this paper we demonstrate by simulation, that the spike features apparent in low-impedance deep brain stimulation (DBS) targeting microelectrode recordings (MER) may not reflect the action potentials of individual neurons. Rather, they are more likely to be compound action potentials from a synch…
