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. [...]

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.

While reinforcement has repeatedly been shown to impact motor adaptation, previous inconsistent findings hinder our mechanistic understanding. To conciliate contradictory views, we used two distinct motor tasks to investigate whether reinforcement differentially modulates two core motor learning processes: between-trial learning resulting from motor planning and within-trial learning supported by the online correction of ongoing movements. [...]

Brain size measures are well-studied and often treated as a confound in volumetric neuroimaging analyses. Yet their relationship with body anthropometric measures and demographics remains underexplored. [...]

Background: Motor asymmetry is a hallmark of Parkinson's disease (PD), but ~20% of patients present with symmetric motor signs, which are associated with faster disease progression and poorer dopaminergic response. The impact of motor symmetry on activities of daily living (ADL) outcomes following subthalamic deep brain stimulation (STN-DBS) remains unclear. [...]

Extended reality (=XR) provides promising opportunities for psychiatry in the future. However, psychiatric patients appear to be particularly vulnerable to virtual exposure. [...]
