Journal ArticleDOI
Impaired electrical signaling disrupts gamma frequency oscillations in connexin 36-deficient mice.
Sheriar G. Hormuzdi,Isabel Pais,Fiona E. N. LeBeau,Stephen K. Towers,Andrei Rozov,Eberhard H. Buhl,Miles A. Whittington,Hannah Monyer +7 more
TL;DR: It is shown that the loss of this protein disrupts gamma frequency network oscillations in vitro but leaves high frequency rhythms, which may involve gap junctions between principal cells (Schmitz et al., 2001), unaffected.
Journal ArticleDOI
Recruitment of parvalbumin-positive interneurons determines hippocampal function and associated behavior.
Elke C. Fuchs,Aleksandar R. Zivkovic,Mark O. Cunningham,Steven J. Middleton,Fiona E. N. LeBeau,David M. Bannerman,Andrei Rozov,Miles A. Whittington,Roger D. Traub,J. Nicholas P. Rawlins,Hannah Monyer +10 more
TL;DR: The effects of insufficient recruitment of fast-spiking cells at the network and behavioral level are shown and the role of this subpopulation for working and episodic-like memory is demonstrated.
Journal ArticleDOI
Single-column thalamocortical network model exhibiting gamma oscillations, sleep spindles, and epileptogenic bursts
Roger D. Traub,Diego Contreras,Mark O. Cunningham,Hilary Murray,Fiona E. N. LeBeau,Anita K. Roopun,Andrea Bibbig,W. Bryan Wilent,Michael J. Higley,Miles A. Whittington +9 more
TL;DR: It is shown that epileptiform bursts, including double and multiple bursts, containing VFO occur in rat auditory cortex in vitro, in the presence of kainate, when both GABA(A) and GABA(B) receptors are blocked.
Journal ArticleDOI
Gap Junctions between Interneuron Dendrites Can Enhance Synchrony of Gamma Oscillations in Distributed Networks
Roger D. Traub,Roger D. Traub,Nancy Kopell,Andrea Bibbig,Andrea Bibbig,Eberhard H. Buhl,Fiona E. N. LeBeau,Miles A. Whittington +7 more
TL;DR: Simulation and electrophysiological evidence is provided that interneuronal gap junctions (presumably dendritic) can enhance the synchrony of gamma oscillations, in spatially extended interneuron networks, with frequency gated by mutual GABAAreceptor-mediated IPSPs.
Journal ArticleDOI
A possible role for gap junctions in generation of very fast EEG oscillations preceding the onset of, and perhaps initiating, seizures
Roger D. Traub,Miles A. Whittington,Eberhard H. Buhl,Fiona E. N. LeBeau,Andrea Bibbig,Stewart Boyd,Helen Cross,Torsten Baldeweg +7 more
TL;DR: An experimentally and clinically testable hypothesis is proposed concerning the origin of very fast EEG oscillations that sometimes precede the onset of focal seizures, which may play a causal role in the initiation of seizures.
