Touch generated by our voluntary movements is attenuated both at the perceptual and neural levels compared with touch of same intensity delivered to body another person or machine. This somatosensory attenuation phenomenon relies on integration input predictions about consequences actions. Previous studies have reported increased in elderly people, proposing an overreliance sensorimotor compensate for age-related declines perception; however, recent results challenged this direct relationship. In a preregistered study, we used force-discrimination task assess whether aging increases increase explained decreased precision individuals. Although 94% sample (

Fatigue is prevalent amongst people with long COVID, but poorly understood. The sensory attenuation framework proposes that impairments in processing lead to heightened perception of effort, driving fatigue. This study aims investigate the role somatosensory COVID fatigue and quantify how relates other prominent symptoms including autonomic dysfunction, mood illness beliefs experience We will recruit 44 individuals neither nor (controls). Our primary objective compare baseline between controls. Additionally, we explore associations processing, fatigability level induced by cognitive physical exertion.

Abstract Within vertebrates, central pattern generators drive rhythmical behaviours, such as locomotion and ventilation. Their generation is also influenced by sensory input various forms of neuromodulation. These capabilities arose early in vertebrate evolution, preceding the evolution cerebellum jawed vertebrates. This later suggestive subsumption architecture that adds functionality to a pre-existing network. From central-pattern-generator perspective, what additional might provide? The suggestion adaptive filter may be able use error learning appropriately repurpose output. Examples include head eye stabilization during locomotion, song learning, context-dependent alternation between learnt motor-control sequences.
