Multivariate associations of motor performance, sleep quality, depressive symptoms, and grey matter volume in younger and mid-to-older adults
Motor performance (MP) is essential for maintaining functional independence, particularly in later life. However, the relationship between MP and sleep quality, depressive symptoms, and their underlying brain substrates remains obscure. [...]

Machine learning to diagnose, classify and predict phenoconversion in isolated REM sleep behavior disorder
Rapid eye movement (REM) sleep behaviour disorder (RBD), particularly its idiopathic/isolated form (iRBD), is a prodromal marker for α-synucleinopathies, including Parkinson's disease, dementia with Lewy bodies and multiple system atrophy. Machine learning (ML) offers opportunities to improve diagnosis and risk stratification in this high-risk group. [...]

Neural processing of emotional stimuli before and after cognitive behavioural therapy for insomnia
BackgroundPrevious research has suggested an association between insomnia disorder (ID) and alterations in emotion processing. Therefore, it is crucial to investigate neurobiological changes in emotion processing in patients with ID before and after Cognitive Behavioral Therapy for Insomnia (CBT-I) and to compare them with healthy controls (HC) with task-based functional magnetic resonance imaging (fMRI).Methods20 patients with ID and 20 HC were included in this study to view five different blocks of pictures with varying emotional arousal, valence, and content (sleep-relatedness) in the fMRI scanner.ResultsA significant Group × Session interaction was identified in the amygdala for both the sleep-related negative contrast (F(1,38) = 4.19, p = .048) and the neutral moderate contrast (F(1,38) = 5.39, p = .026).

Impaired sleep microarchitecture is associated with locus coeruleus degeneration in Parkinson's disease
Abstract: Sleep disorders are common non-motor symptoms of Parkinson's disease (PD) that significantly impact patients' quality of life. Specifically, alterations in sleep microstructure - such as reduced slow-wave activity and sleep spindles - are prevalent in PD. [...]

Consistently longer silent gaps in autistic speaker pairs across three conversational contexts
We investigated the timing of turn-taking in matched autistic compared to non-autistic pairs of adult speakers. Turn-taking—the organisation of who speaks when—is the fundamental mechanism of communicative interaction, and has been found to be remarkably fast and robust across different groups of speakers. [...]
