Contracted functional connectivity profiles in autism

2024, Clinical /

A new publication by Clara F. Weber from her time at the Multimodal Imaging and Connectome Analysis Laboratory (head: Prof Boris Bernhardt) at the Montreal Neurological Institute, McGill University in Canada.    Objective Autism spectrum disorder (ASD) is a neurodevelopmental condition that is associated with atypical brain network organization, with prior work suggesting differential connectivity […]

Computational modeling shows confirmation bias during formation and revision of self-beliefs

Science /

Abstract Self-belief formation and revision strongly depend on social feedback. Accordingly, self-beliefs are subject to (re)evaluation and updating when facing new information. However, it has been shown that self-related learning is rarely purely information-driven. Instead, self-related learning is susceptible to a wide variety of biases. Among them is the confirmation bias, which can render updating

Altered physiological, affective, and functional connectivity responses to acute stress in patients with alcohol use disorder

2024, Clinical, Hormones/Neuromodulators /

Background There is evidence that the processing of acute stress is altered in alcohol use disorder (AUD), but little is known about how this is manifested simultaneously across different stress parameters and which neural processes are involved. The present study examined physiological and affective responses to stress and functional connectivity in AUD. Methods Salivary cortisol

Examining self-belief formation through artificial beliefs

Science /

Abstract Psychological research has addressed key questions about self-beliefs, such as when they are formed, how they are shaped, or what functions they might have. The fundamental question of how we arrive at these self-beliefs in the first place has mostly been neglected, and there is currently no mechanistic description of the underlying processes. While

Neurocomputational mechanisms underlying maladaptive self-belief formation in depression

Science /

Abstract A core symptom of major depression is maladaptive self-beliefs. These are perpetuated by negatively biased feedback processing. Understanding the neurocomputational mechanisms of biased belief updating may help to counteract maladaptive beliefs. The present study uses functional neuroimaging to examine neural activity associated with prediction error-based learning in depression and healthy controls. We hypothesized that
