BRONZE AGE ANTLER AND BONE SPINDLE WHORLS IN THE SOUTHEAST OF IBERIA

open access: yesCuadernos de Prehistoria y Arqueología de la Universidad de Granada, 2019
The elaboration of spindle whorls for the manufacture of thread using spindles is attested in the Iberian Peninsula from the end of the Neolithic. There is no evidence, however, of the use of materials other than stone or pottery to produce spindle whorls during this period.

Novel murine closed‐loop auditory stimulation paradigm elicits macrostructural sleep benefits in neurodegeneration

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Boosting slow‐wave activity (SWA) by modulating slow waves through closed‐loop auditory stimulation (CLAS) might provide a powerful non‐pharmacological tool to investigate the link between sleep and neurodegeneration. Here, we established mouse CLAS (mCLAS)‐mediated SWA enhancement and explored its effects on sleep deficits in neurodegeneration,

Ground stone tool assemblages at the end of the Chalcolithic period: A preliminary analysis of the Late Chalcolithic sites in the Fazael Valley

open access: yesJournal of Lithic Studies, 2016
The very Late Chalcolithic sites of the Fazael Valley exhibit changes in settlement patterns and material culture. This paper presents the analysis of the ground stone tool assemblages of these sites, and includes the combination of attribute analysis ...

Sleep Slow Wave‐Bistability and the Connection Between the Sleeping Brain and the Environment—Neurobiological Considerations

open access: yesJournal of Sleep Research, EarlyView.
Bistability is an inherent working mode of NREM sleep. Those bistable patterns ‐ sleep slow waves, K‐complexes, and the cyclic alternating pattern (on a longer, several seconds' time‐scale) ‐ have a double function; they protect sleep and provide an interface between the brain and the environment for information‐transfer during sleep.

Tone‐Evoked Sleep Electroencephalographic Slow Oscillations as a Function of Peripheral Rhythms: New Insights Into the Brain–Heart Integration

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Recent studies have shown that acoustic stimulation, a common neuromodulation technique, can enhance slow‐wave activity (SWA), which is associated with immune, autonomic nervous system activity and cognitive health benefits. Despite some disagreement, many studies suggest that maximising tone‐evoked SWA depends on the timing of the acoustic ...

Convex Loom Weights in the Akarçay Basin and its Surroundings

open access: yesAnadolu Araştırmaları
The Akarçay basin and its surrounding mountainous areas have long been vital for livestock activities and wool and textile production, both in the Bronze Ages and today.

The Effect of Closed‐Loop Auditory Stimulation on Memory Consolidation and Sleep Physiology in an Ecological Setting

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Slow wave sleep plays a crucial role in overnight memory consolidation, with slow oscillations serving as a critical mechanism. Recent studies have identified closed‐loop auditory stimulation as an effective method to enhance slow oscillatory activity during slow wave sleep, thereby facilitating memory consolidation.

Differential Nap‐To‐Nap Stability of Sleep Spindles, Slow Waves, and their Temporal Coupling: An Exploratory Study

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Slow waves and sleep spindles characterise non‐rapid eye movement (NREM) sleep and support cognitive and plasticity‐related functions. While their stability across nights is well established, less is known about their consistency across daytime naps.

Refined Division of Sleep Stages in the Mouse Based on Distributed Deep Electrodes and Underlying Infra‐Slow Oscillation

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT The mouse sleep is mostly recorded with only epidural electrodes and divided simply into NREM and REM stages. With the help of distributed intracerebral triplet electrodes, we searched for possible new electrophysiological signatures to characterise more specific sleep substages within the timeframe of seconds to tens of minutes.
