- Noradrenergic neurons expressing Fos during waking and paradoxical sleep deprivation in the ratLucienne Leger
Universite de Lyon, Lyon, France
J Chem Neuroanat 37:149-57. 2009..They further suggest that the inhibitory effect of noradrenaline on PS may be due to the A1/C1, A2 and to a lesser degree to A5 neurons but not from those of the LC as previously hypothesized...

McGill University, Douglas Mental Health University Institute, Montreal, Quebec H4H 1R3, Canada

CNRS, UMR5167, Physiopathologie des réseaux neuronaux du cycle veille sommeil, Lyon, France

- Self-generated theta oscillations in the hippocampusRomain Goutagny
Douglas Mental Health University Institute, McGill University, Department of Psychiatry, Quebec, Canada
Nat Neurosci 12:1491-3. 2009..These oscillators were organized along the septotemporal axis and arose independently from CA3. Our results suggest that CA1 theta rhythm can emerge from the coupling of multiple autonomous hippocampal theta oscillators...

Neuroreport 16:1069-73. 2005..These results suggest that neurons containing melanin-concentrating hormone are not active during waking and that the lack of a potent GABAergic influence during waking is consistent with their role in sleep regulation...
