Filter by:The goal of this single center non-interventional fMRI and EEG study is to assess the neural bases of social cognitive processing in healthy individuals, and whether/how their responsiveness is modulated by ageing. The main questions it aims to answer are: - are there specific brain regions where individual differences in social cognitive performance reflect well-established metrics of social cogntion such as empathy and mentalizing? - is there a relationship, at the behavioral and neural levels, between ageing-related changes in social cognitive performance and empathy/mentalizing? Healthy participants will be recruited for: - a behavioral assessment including multiple tests of social cognition focused on empathy and mentalizing; - for half participants: a fMRI session to collect data concerning a) brain activity associated with action observation and social cognitive processing, b) brain structural morphometriy (grey-matter volume/density), and c) brain structural connectivity (diffusion weighted imaging) - for half participants: a EEG session to collect data concerning brain responsiveness to social cognitive processing with higher temporal resolution than that afforded by fMRI. Results will provide an useful baseline for investigating alterations of social cognitive processing, and of their neural bases, in pathological conditions.
This behavioral study on healthy participants aims to provide a baseline reference for assessing alterations of decision-making performance in pathological conditions. To this purpose, this single center non-interventional behavioral study will assess the extent to which decision-making performance is affected by distinct experimental manipulations, as well as by ageing effects, in 200 healthy individuals. The main questions it aims to answer are: - to what extent is decision-making performance stable, within individuals, regardless of non-economic manipulations concerning stimuli perceptual features as well as type of processing and motor response required to participants? - are these manipulations additionally influenced by participants' age? Healthy participants will be recruited for distinct behavioral studies assessing the effects of the aforementioned manipulations of distinct metrics of decision-making performance, such as loss aversion, risk aversion, and delay discounting.
The goal of this single center non-interventional fMRI study is to assess the neural bases of decision-making and executive functioning in healthy individuals,and whether/how their responsiveness is modulated by ageing. The main questions it aims to answer are: 1. are there specific neural correlates for ageing effects on executive functioning (particularly inhibitory control) and decision-making? 2. Is there a relationship, at the behavioral and neural levels, between ageing-related changes in executive functioning and decision-making? Healthy participants will be recruited for 1. a behavioral assessment including multiple tests of decision-making and executive functioning/inhibitory control; 2. a fMRI session to collect data concerning a) brain activity associated with decision-making and executive functioning, b) brain structural morphometriy (grey-matter volume/density), and c) brain structural connectivity (diffusion weighted imaging). Results will provide an useful baseline for investigating alterations of decision-making and executive functioning, and of their neural bases, in pathological conditions.
Study to determine the bioequivalence of a zanubrutinib tablet compared to capsules in healthy adult participants.
This project aims to investigate executive functioning abilities (primary outcome) and quality of sleep (secondary outcome) in patients with COVID-19 (while distinguishing between those with and without sleep fragmentation), compared with an age- and education matched control group of healthy individuals who did not experience contagion. Prefrontal electrical activity will be recorded with EEG in patients, and related to sleep and cognitive-executive metrics. The main questions it aims to answer are: - is executive functioning impaired in COVID-19 patients compared with individuals who were not infected? - is there a relationship between altered sleep and impaired executive functioning in COVID-19 patients? - is such relationship related to altered prefrontal brain activitity in COVID-19 patients?
The primary objectives of this study are to investigate the safety and serum pharmacokinetics of 5-MeO-DMT in healthy volunteers in a double-blind, placebo-controlled, randomized study design with single, injected doses of GH002 and in an open-label, non-randomized study design with intra-subject dose-escalation of GH002. As secondary objectives, the PK/ pharmacodynamic relationship, PD profile of GH002 as evaluated by its psychoactive effects and impact on cognitive performance, and the serum PK of the metabolite bufotenine are also assessed.
The goal of this observational study is to learn about spatial and temporal nociceptive filtering in adolescents with chronic overlapping pain conditions (COPCs). The main questions it aims to answer are: 1. If spatial and temporal filtering of nociceptive information is disrupted in youth with COPCs compared with youth with localized pain conditions and healthy controls. 2. If disrupted nociceptive processing at baseline is associated with the transition from a single localized pain condition to COPCs in youth. Participation includes: - quantitative sensory testing - blood draw - sleep assessment - questionnaires
The primary objective of this study is to evaluate the safety and tolerability of E2086 following administration of a single oral doses in healthy adult and elderly participants.
Resistant starch (RS), a type of dietary fiber, was shown to have beneficial effects on human health through its impact on microbes present in the intestine. However, the effects of RS on the gut microbiota and in turn, on human health, can vary between individuals. Consequently, everyone may not reap the same health benefits by eating high amounts of RS. Factors predicting how an individual's gut microbes as well as the beneficial metabolites produced by these microbes respond to RS supplementation would be helpful in developing precision nutrition approaches that maximize the benefits of dietary fiber intake. The objective of this study was to evaluate candidate predictors of gut microbiota response to RS supplementation.
This is a Phase 1, double-blind, randomized, placebo-controlled study to investigate single and multiple intravenous infusions of improved cell-permeable nuclear import inhibitor (iCP NI) in healthy subjects.
