Coupled sleep rhythms for memory consolidation

How do passing moments turn into lasting memories? Sheltered from external tasks and distractions, sleep constitutes an optimal state for the brain to reprocess and consolidate previous experiences. Recent work suggests that consolidation is governed by the intricate interaction of slow oscillations (SOs), spindles, and ripples – electrophysiological sleep rhythms that orchestrate neuronal processing and […]

Short term effects of contralateral tendon vibration on motor unit discharge rate variability and force steadiness in people with Parkinson’s disease

BackgroundVibration of one limb affects motor performance of the contralateral limb, and this may have clinical implications for people with lateralized motor impairments through vibration-induced increase in cortical activation, descending neural drive, or spinal excitability.ObjectiveThe objective of this study was to evaluate the effects of acute biceps brachii tendon vibration on force steadiness and motor […]

Impact of olfactory function on the trajectory of cognition, motor function, and quality of life in Parkinson’s disease

BackgroundOlfactory dysfunction in Parkinson’s disease (PD) is associated with more severe phenotypes, but trajectories of cognitive function, disease severity, and subdomains of quality-of-life measurements in patients with distinct olfactory profiles remain underexplored.ObjectiveTo analyze the influence of olfaction on trajectories of clinical parameters in patients with PD.DesignRetrospective cohort study.SubjectsFrom October 2016 to May 2021, the study […]
