"Heterogeneity & Synchronization in the Olfactory Bulb"

Bard Ermentrout, Professor, University of Pittsburgh

Host: Adrienne Fairhall
Co-hosting Department: Computational Neuroscience Training Program

Synchronous neural oscillations are found throughout the brain and are believed to contribute to information processing and coding. One mechanism of synchrony is through the driving of intrinsic neural oscillators with correlated noise. Here we use some recently developed theory in conjunction with experimental recordings in the mouse olfactory bulb to study the effects of heterogeneity on the ability of neurons to synchronize. We find, somewhat surprisingly, that in some circumstances heterogeneity will improve synchronization. We also find that differences in frequency between oscillators leads to a resonance with respect to the correlation time of the noise.
