Differential effects of a single dose of Lisdexamfetamine and Guanfacine on cognitive function in children with ADHD Open
Background Attention-Deficit/Hyperactivity Disorder (ADHD) is associated with cognitive difficulties which improve with traditional stimulant and non-stimulant medications. However, there is limited evidence on the cognitive effects of the…

Cuff Algometry Induces Large Yet Variable Conditioned Pain Modulation Effects Open
Conditioned pain modulation (CPM) paradigms provide a proxy measure of activity in the descending pain modulatory system. Cuff-pressure-algometry offers a standardised CPM assessment tool although comprehensive validation in large samples …

Test-retest reliability of sensorimotor activity measured with spinal cord fMRI Open
Establishing the reliability of spinal cord functional magnetic resonance imaging (fMRI) is critical before employing it to assess experimental or clinical interventions. Previous studies have mapped human motor activity primarily to the i…

The individual and situational factors predicting unethical behaviour in the workplace: a direct and conceptual replication of Jones & Kavanagh (1996) Open
Intentions to act unethically in the workplace are purported to be driven by a number of situational and individual factors. Across two seminal vignette experiments, Jones and Kavanagh reported inconsistent effect sizes for manager and pee…

Automatic segmentation of the spinal cord nerve rootlets Open
Precise identification of spinal nerve rootlets is relevant to delineate spinal levels for the study of functional activity in the spinal cord. The goal of this study was to develop an automatic method for the semantic segmentation of spin…

Double-Blind, Sham-Controlled Randomized Trial Testing the Efficacy of fMRI Neurofeedback on Clinical and Cognitive Measures in Children With ADHD Open
Contrary to the hypothesis, the study findings do not suggest that fMRI-NF of the rIFC is effective in improving clinical symptoms or cognition in boys with ADHD.
