Sleep cycles are defined as episodes of non-rapid eye movement (non-REM) sleep followed by an episode REM sleep. Fractal or aperiodic neural activity is a well-established marker arousal and stages measured using electroencephalography. We introduce new concept ‘fractal cycles’ sleep, time interval during which series fractal descend to their local minimum ascend the next maximum. assess correlations between classical (i.e. non-REM – REM) cycle durations study with skipped The sample...
Sleep research heavily relies on Polysomnography (PSG) recordings to assess sleep architecture. While effective, this method is time-consuming and requires substantial resources labor. Modern wearable devices provide a promising alternative for monitoring as they are easy wear maintain. However, these constrained by limited number of channels comparatively lower data quality, which often leads unreliable outcomes derived from partial readings. To address this, we propose using multiple...
Abstract Sensory input is inherently noisy while the world predictable. When multiple observations of same object are available, integration available information necessarily increases reliability a estimate. Optimal instances sensory evidence has already been demonstrated during multisensory perception but could benefit unimodal as well. In present study 330 participants observed sequence four orientations and were cued to report one them. Reports biased by all simultaneously memorized...

Humans typically make several saccades per second. This provides a challenge for the visual system as locations are largely coded in retinotopic (eye-centered) coordinates. Spatial remapping, updating of location coordinates items visuospatial memory, is assumed to be limited robust, capacity-limited and attention-demanding working memory (WM). Are pre-attentive, maskable, sensory representations (e.g. fragile FM) also remapped? We directly compared trans-saccadic WM (tWM) FM (tFM) retro-cue...
Nocturnal human sleep consists of 4 – 6 ninety-minute cycles defined as episodes non-rapid eye movement (non-REM) followed by an episode REM sleep. While are considered fundamental components sleep, their functional significance largely remains unclear. One the reasons for a lack research progress in this field is absence “data-driven” definition cycles. Here, we proposed to base such on fractal (aperiodic) neural activity, well-established marker arousal and stages.We explored temporal...
The state of becoming aware that one is dreaming within an ongoing dream, referred to as lucid (LD), can occur spontaneously. Yet, since the occurrence spontaneous LD relatively rare, various methods have been proposed induce LD. Existing scientific literature, however, has constrained by either small sample sizes with limited generalizability, or reliance on subjective measures without physiological signals. To address these limitations, we recorded verifiable using 2-channel EEG and...
Abstract Accessing the contents of visual short-term memory (VSTM) is compromised by information bottlenecks and interference between memorization recall. Retro-cues, displayed after offset a stimulus prior to onset probe stimulus, indicate test item improve performance in VSTM tasks. It has been proposed that retro-cues aid recall transferring from high-capacity store into working (multiple-store hypothesis). Alternatively, could redistributing resources within same (low-capacity)...

Sensitive periods have previously been identified for several human visual system functions. Yet, it is unknown to what degree the development of visually guided oculomotor control depends on early experience-for example, whether and humans whose sight was restored after a transient period congenital deprivation are able conduct eye movements. In present study, we developed new calibration analysis techniques tracking data contaminated with pervasive nystagmus, which typical this population....
Lucid dreaming allows conscious awareness and control of vivid dream states, however its rarity instability make neuroscientific experimentation challenging. Recent advances in wearable neurotechnology, large-scale collaborations, citizen neuroscience artificial intelligence increasingly facilitate the decoding this intriguing phenomenon.

What we see is intimately linked to how actively and systematically explore the world through eye movements. However, it unknown what degree visual experience during early development necessary for such systematic exploration emerge. The present study investigated behavior in ten human participants whose sight had been restored only childhood or adulthood, after a period of congenital blindness due dense bilateral cataracts. Participants freely explored real-world images while their...
Visual short term memory allows us to access visual information after termination of its retinal input. Generally, a distinction is made between robust, capacity-limited form (working memory, WM) and high-capacity, pre-attentive, maskable forms (sensory e.g. fragile FM). Eye movements pose challenge for spatial because retinotopically coded coordinates need be updated with every saccade (spatial remapping). This computationally intense process has been considered strictly limited WM. To...
