The sleep-wakefulness cycle of Wistar rats with spontaneous absence-like epilepsy
Acta Scientiarum: Biological Sciences, 2015 Possible interactions between the sleep-wakefulness cycle and a new kind of spontaneous epilepsy, expressed as absence-like seizures and spike-wave bursts in FMUSP rats, are evaluated.

The spatiotemporal pattern of the human electroencephalogram at sleep onset after a period of prolonged wakefulness [PDF]
, 2019 During the sleep onset (SO) process, the human electroencephalogram (EEG) is characterized by an orchestrated pattern of spatiotemporal changes. Sleep deprivation (SD) strongly affects both wake and sleep EEG, but a description of the topographical EEG ...

EEG oscillations during sleep and dream recall. State- or trait-like individual differences? [PDF]
, 2015 Dreaming represents a peculiar form of cognitive activity during sleep. On the basis of the well-known relationship between sleep and memory, there has been a growing interest in the predictive role of human brain activity during sleep on dream recall ...

The Cortical States of Wakefulness [PDF]
Frontiers in Systems Neuroscience, 2019 Cortical neurons process information on a background of spontaneous, ongoing activity with distinct spatiotemporal profiles defining different cortical states. During wakefulness, cortical states alter constantly in relation to behavioral context, attentional level or general motor activity.

Investigation of the near-wake behaviour of a utility-scale wind turbine [PDF]
, 2019 Super-large-scale particle image velocimetry and flow visualization with natural snowfall is used to collect and analyze multiple datasets in the near wake of a 2.5 MW wind turbine. Each dataset captures the full vertical span of the wake from a different perspective.
