  1. pmc Sleep in Kcna2 knockout mice
    Christopher L Douglas
    Department of Psychiatry, University of Wisconsin, Madison, WI, 53719, USA
    BMC Biol 5:42. 2007
    ..To address this issue, we studied sleep in Kcna2 knockout (KO) mice. Kcna2 codes for Kv1.2, the alpha subunit of a Shaker-like voltage-dependent potassium channel with high expression in the mammalian thalamocortical system...
  2. pmc Electrophysiological correlates of sleep homeostasis in freely behaving rats
    Vladyslav V Vyazovskiy
    Department of Psychiatry, University of Wisconsin Madison, Madison, WI, USA
    Prog Brain Res 193:17-38. 2011
    ..Taken together, these data suggest that homeostatic changes in sleep EEG are the result of altered neuronal firing and synchrony, which in turn arise from changes in functional neuronal connectivity...
  3. pmc Cortical firing and sleep homeostasis
    Vladyslav V Vyazovskiy
    Department of Psychiatry, University of Wisconsin Madison, Madison, WI 53719, USA
    Neuron 63:865-78. 2009
    ..Changes in firing patterns in NREM sleep correlate with changes in slow-wave activity, a marker of sleep homeostasis. Thus, the systematic increase of firing during wakefulness is counterbalanced by staying asleep...
  4. pmc Sleep homeostasis and cortical synchronization: III. A high-density EEG study of sleep slow waves in humans
    Brady A Riedner
    Department of Psychiatry, University of Wisconsin, Madison, WI 53719, USA
    Sleep 30:1643-57. 2007
    ..Here, we investigated the model's predictions in humans by using all-night high-density (hd)-EEG recordings to explore slow-wave parameters over the entire cortical mantle...
  5. pmc Local sleep in awake rats
    Vladyslav V Vyazovskiy
    Department of Psychiatry, University of Wisconsin Madison, Madison, 6001 Research Park Boulevard, Wisconsin 53719, USA
    Nature 472:443-7. 2011
    ..Thus, although both the EEG and behaviour indicate wakefulness, local populations of neurons in the cortex may be falling asleep, with negative consequences for performance...

    Michael B Dash
    Department of Psychiatry, and Neuroscience Training Program, University of Wisconsin Madison, Madison, WI 53719, USA

    J Neurophysiol 101:1921-31. 2009

    Proc Natl Acad Sci U S A 107:15939-44. 2010
    ..Analysis of cumulative slow wave energy demonstrated that the loss of SWA during SR was compensated by the end of the second recovery day. Thus, the homeostatic regulation of sleep is preserved under conditions of chronic SR...
