The paper develops biophysical and phenomenological models to explain in vivo burst firing in electrosensory pyramidal cells, showing how intrinsic conductances, Ca2+ dynamics, and synaptic noise interact to produce bursting activity.

The paper shows burst firing in neural populations creates invariant representations of natural communication signals, demonstrated through recordings and computational modeling.

The paper uses computational modeling to show that extrinsic synaptic input is the main factor causing spiking heterogeneity in sensory neurons in vivo.
