Abstract Whereas the effect of vagal nerve stimulation on emotional states is well established, its cognitive functions still unclear. Recent rodent studies show that activation enhances reinforcement learning and neuronal dopamine release. The influence in humans unknown. Here, we studied transcutaneous eight long-standing seizure-free epilepsy patients, using a well-established forced-choice reward-based paradigm cross-sectional, within-subject study design. We investigated effects overall...
Abstract The vagus nerve constitutes a key link between the autonomic and central nervous system. Previous studies provide evidence for impact of vagal activity on distinct cognitive processes including functions related to social cognition. Recent in animals humans show that stimulation is associated with enhanced reward-seeking dopamine-release brain. Social interaction recruits similar brain circuits reward processing. We hypothesize (VNS) boosts rewarding aspects behavior compare...
In order to identify more refined dimensions of social-communication impairments in autism spectrum disorder (ASD) a previous study applied exploratory and confirmatory factor analyses diagnostic algorithm scores the observation schedule (ADOS), Module 3. A three-factor model consisting repetitive behaviors, 'Basic Social-Communication' 'Interaction quality' (IQ) was established confirmed. The current aimed replicate this an independent sample. To advance our understanding latent structure...
Abstract The vagus nerve constitutes a key link between the vegetative and central nervous system. However, impact of vagal activity on cognitive processes is largely unknown. Recent studies in animals humans show that stimulation associated with enhanced reward-seeking dopamine-release brain. Social interaction recruits similar brain circuits to reward processing. We hypothesize (VNS) boosts rewarding aspects social behavior compare transcutaneous VNS (tVNS) sham 19 epilepsy patients...
