DOI: 10.1002/hbm.26295
Abstract: The present study performed a brain‐wide network analysis of resting‐state magnetoencephalograms recorded from 53 healthy participants to visualize elaborate brain maps of phase‐ and amplitude‐derived graph‐theory metrics at different frequencies. To achieve this, we conducted… read more here.

DOI: 10.1016/j.celrep.2017.09.087
Abstract: Serotonin-producing neurons profusely innervate brain regions via long-range projections. However, it remains unclear whether and how endogenous serotonergic transmission specifically influences regional or global functional activity. We combined designed receptors exclusively activated by designed drugs (DREADD)-based chemogenetics… read more here.

DOI: 10.1038/s41467-018-07752-3
Abstract: Rapid eye movement sleep (REMS) is a peculiar brain state combining the behavioral components of sleep and the electrophysiological profiles of wake. After decades of research our understanding of REMS still is precluded by the… read more here.

DOI: 10.1038/s41593-018-0164-7
Abstract: Slow waves (0.5–4 Hz) predominate in the cortical electroencephalogram during non-rapid eye movement (NREM) sleep in mammals. They reflect the synchronization of large neuronal ensembles alternating between active (UP) and quiescent (Down) states and propagating along… read more here.

DOI: 10.1038/s41598-021-90364-7
Abstract: The hippocampus is critical for learning and memory and may be separated into anatomically-defined hippocampal subfields (aHPSFs). Hippocampal functional networks, particularly during resting state, are generally analyzed using aHPSFs as seed regions, with the underlying… read more here.
