How representative are neuroimaging samples? Large-scale evidence for trait anxiety differences between MRI and behaviour-only research participants.
(2020-04)
Over the past three decades, MRI has become a key tool to study how cognitive processes are implemented in the human brain. However, the question of whether participants recruited into MRI studies differ from participants ...
Neurocognitive processes in d-cycloserine augmented single-session exposure therapy for anxiety: A randomized placebo-controlled trial
(2020-06)
Drugs targeting N-methyl-d-aspartate (NMDA) receptors and the ability to learn new associations have been proposed as adjunct treatments to boost the success of exposure therapy for anxiety disorders. However, the effects ...
Lithium modulates striatal reward anticipation and prediction error coding in healthy volunteers
(2020-10)
Lithium is one of the most effective mood-stabilizing medications in bipolar disorder. This study was designed to test whether lithium administration may stabilize mood via effects on reward processing. It was hypothesized ...
When Helping is Risky: Behavioral and Neurobiological Mechanisms of Prosocial Decisions Entailing Risk.
(2020-03)
Helping others can entail risks. Doctors that treat infectious patients may risk their own health, intervening in a fight can lead to injury, and organ donations can lead to medical complications. When helping others comes ...
Advances in the computational understanding of mental illness
(2020-07)
Computational psychiatry is a rapidly growing field attempting to translate advances in computational neuroscience and machine learning into improved outcomes for patients suffering from mental illness. It encompasses both ...
Inducing Affective Learning Biases with Cognitive Training and Prefrontal tDCS: A Proof-of-Concept Study
(2020-10)
Cognitive models of mood disorders emphasize a causal role of negative affective biases in depression. Computational work suggests that these biases may stem from a belief that negative events have a higher information ...
