Dorsal and median raphe neuronal firing dynamics characterized by non-linear metrics

The paper uses non-linear metrics to differentiate firing dynamics between dorsal and median raphe neurons in rats, finding that OP Entropy is effective in distinguishing these neurons.

Low Frequency Oscillations drive EEG's complexity changes during wakefulness and sleep

This study shows that low-frequency brain oscillations drive changes in EEG complexity during sleep and wakefulness in rats.

OFF-periods reduce the complexity of neocortical activity during sleep

The paper shows that synchronous neuronal OFF-periods during slow-wave sleep reduce electroencephalographic signal complexity by trapping cortical dynamics, making activity more recurrent and deterministic.

Gamma band alterations and REM-like traits underpin the acute effect of the atypical psychedelic ibogaine

This study investigates the electrophysiological effects of ibogaine in rats, finding increased gamma oscillation power with reduced coherence and complexity, suggesting REM sleep traits in the psychedelic state.

Communication through coherence by means of cross-frequency coupling

The paper investigates whether cross-frequency coupling (CFC) between theta and fast gamma oscillations supports communication through coherence (CTC) by examining phase-dependent synchronization across the neocortex during REM sleep.

Electrocortical temporal complexity during wakefulness and sleep: an updated account

This study shows that electrocortical temporal complexity decreases during sleep regardless of electrode configuration, suggesting brain-generated differences in complexity between wakefulness and sleep.

Decreased electrocortical temporal complexity distinguishes sleep from wakefulness

The paper uses permutation entropy to show that electrocortical complexity decreases during sleep compared to wakefulness in rats, suggesting a global thalamo-cortical pattern change.

Nasal respiration entrains neocortical long-range gamma coherence during wakefulness

This study shows nasal respiration entrains inter-cortical gamma coherence during wakefulness but not during sleep.
