Negative valence in Obsessive-Compulsive Disorder: A worldwide mega-analysis of task-based functional neuroimaging data of the ENIGMA-OCD consortium.

Objective: Obsessive-compulsive disorder (OCD) is associated with altered brain function related to processing of negative emotions. To investigate neural correlates of negative valence in OCD, we pooled fMRI data of 633 individuals with OCD and 453 healthy controls from 16 studies using different negatively-valenced tasks across the ENIGMA-OCD Working-Group.

Methods: Participant data were processed uniformly using HALFpipe, to extract voxelwise participant-level statistical images of one common first-level contrast: negative vs.

Can neutral episodic memories become emotional? Evidence from facial expressions and subjective feelings.

Maladaptive emotional memories are a transdiagnostic feature of mental health problems. Therefore, understanding whether and how emotional memories can change might help to prevent and treat mental disorders. We tested whether neutral memories of naturalistic events can retroactively acquire positive or negative affect, in a preregistered three-day Modification of Valence in Episodes (MOVIE) paradigm.

Can the Brain Strategically Go on Automatic Pilot? The Effect of If-Then Planning on Behavioral Flexibility.

People often have good intentions but fail to adhere to them. Implementation intentions, a form of strategic planning, can help people to close this intention-behavior gap. Their effectiveness has been proposed to depend on the mental formation of a stimulus-response association between a trigger and target behavior, thereby creating an "instant habit.

Systematic scoping review of the concept of 'genetic identity' and its relevance for germline modification.

EU legislation prohibits clinical trials that modify germ line 'genetic identity'. 'Genetic identity' however, is left undefined. This study aims to identify the use of the term 'genetic identity' in academic literature, and investigate its relevance for debates on genetic modification.
