The authors studied the transformation of infraslow oscillations of brain potentials in 15 patients with neuroses during 50 sessions of hypnosis. The results of such studies permitted to distinguish some important traits in the changes of infraslow oscillations of brain potentials in different stages of hypnosis. It is concluded that a study of these changes during hypnosis may establish some correlations between the physiological state of the brain and the unconscious mental processes.

Elucidating human cerebral cortex function is essential for understanding the physiological basis of both healthy and pathological brain states. We obtained extracellular local field potential recordings from cortical slices of neocortical tissue from refractory epilepsy patients. Multi-electrode recordings were combined with histological information, providing a two-dimensional spatiotemporal characterization of human cortical dynamics in control conditions and following modulation of the excitation/inhibition balance.

As the brain transitions from wakefulness to sleep, processing of external information diminishes while restorative processes, such as glymphatic removal of waste products, are activated. Yet, it is not known what drives brain clearance during sleep. We here employed an array of technologies and identified tightly synchronized oscillations in norepinephrine, cerebral blood volume, and cerebrospinal fluid (CSF) as the strongest predictors of glymphatic clearance during NREM sleep.

Sleep spindles are cortical electrical oscillations considered critical for memory consolidation and sleep stability. The timing and pattern of sleep spindles are likely to be important in driving synaptic plasticity during sleep as well as preventing disruption of sleep by sensory and internal stimuli. However, the relative importance of factors such as sleep depth, cortical up/down-state, and temporal clustering in governing sleep spindle dynamics remains poorly understood.

Article Synopsis
- Impaired sleep is common with aging and is linked to the onset of Alzheimer's disease; researchers studied the effects of sleep deprivation on both healthy mice and a mouse model of Alzheimer's.
- After sleep deprivation, both groups showed increased EEG slow-wave activity, but only healthy mice exhibited enhanced norepinephrine oscillations typical of good sleep.
- The Alzheimer’s model mice didn't show this enhancement 24 hours post-deprivation, along with a buildup of amyloid-β protein, suggesting that their disrupted sleep patterns may increase the risk of developing Alzheimer's.

Article Synopsis
- The study examined brain connectivity in 51 CRPS patients compared to 50 control subjects, finding both weak and some specific differences in functional connectivity.
- It highlighted lower connectivity between the periaqueductal gray matter and the anterior insula, and higher connectivity within the reward system, indicating potential mechanisms in CRPS pain modulation.
- Importantly, the researchers observed lower data quality in CRPS patients, suggesting that findings on connectivity should be re-evaluated in future studies for better reliability.
