Hippocampal Neocortical Coupling Varies as a Function of Depth of NREM Sleep
Rachel Swanson,Jayeeta Basu,György Buzsáki · COSYNE 2022
During NREM sleep, the brain is in a self-organized regime in which alternations between spiking and near cessation of spiking propagate along the forebrain, termed slow oscillations (SOs) in the neocortex and SPW-Rs in the hippocampus. Both gain and loss of function studies have demonstrated the importance of tight temporal coordination between SOs and SPW-Rs for systems consolidation, and this temporal coupling has been observed across pairs of regions many synapses removed from one another. However, the spatial extent to which coupling between SPW-Rs and SOs occurs across regions at any one
