Journal ArticleDOI
Activation of c‐fos in GABAergic neurones in the preoptic area during sleep and in response to sleep deprivation
TL;DR: Findings demonstrate that a majority of MnPN and vlPOA neurones that express Fos‐IR during sustained spontaneous sleep are GABAergic, and demonstrate that sleep deprivation is associated with increased activation of GABAergic neurones in the MnPNand vl POA.
Journal ArticleDOI
Sleep-waking discharge patterns of median preoptic nucleus neurons in rats
TL;DR: It is hypothesize that these vlPOA and MnPN neuronal populations act as parts of a GABAergic/galaninergic sleep‐promoting (‘anti‐waking’) network which exercises inhibitory control over waking‐promoted systems.
Journal ArticleDOI
Sleep deprivation reduces proliferation of cells in the dentate gyrus of the hippocampus in rats
Ruben Guzman-Marin,Natalia Suntsova,Natalia Suntsova,Darya Stewart,Hui Gong,Ronald Szymusiak,Dennis McGinty +6 more
TL;DR: It is suggested that sleep deprivation reduces proliferation of cells in the DG of the dorsal hippocampus, which gives rise to progenitor cells, which have the potential to differentiate into neurons.
Journal ArticleDOI
Suppression of hippocampal plasticity-related gene expression by sleep deprivation in rats.
Ruben Guzman-Marin,Zhe Ying,Natalia Suntsova,Melvi Methippara,Tariq Bashir,Ronald Szymusiak,Fernando Gomez-Pinilla,Dennis McGinty +7 more
TL;DR: Stepwise regression analysis suggested that loss of REM sleep underlies the effects of SD on hippocampal BDNF, Synapsin I and CREB mRNA levels, whereas loss of NREM sleep underlie the effects on CAMKII mRNA.
Journal ArticleDOI
Sleep deprivation suppresses neurogenesis in the adult hippocampus of rats.
Ruben Guzman-Marin,Natalia Suntsova,Natalia Suntsova,Melvi Methippara,Richard Greiffenstein,Ronald Szymusiak,Dennis McGinty +6 more
TL;DR: Sleep deprivation (SD) reduces neurogenesis in the DG by affecting both total proliferation and the percentage of cells expressing a mature neuronal phenotype, hypothesize that sleep provides anabolic or signaling support for proliferation and cell fate determination.
