Catechol-O-methyltransferase activity does not influence emotional processing in men
(2022-04)
Background: Catechol-O-methyltransferase (COMT) regulates cortical dopaminergic transmission and prefrontal-dependent cognitive function. However, its role in other cognitive processes, including emotional processing, is ...
Symptom Dynamics and Attention in Depression: Fatigue and Low Positive Affect are Associated With Reduced Orienting Efficiency
(2022-02)
Depression is a heterogeneous mental disorder involving a complex interplay between
potential etiological and maintenance factors. The current study examined how depression
heterogeneity is related to attentional ...
Pramipexole Enhances Reward Learning by Preserving Value Estimates

thought to act by altering how individuals learn from rewarding experiences. However, the nature of these
reward learning ...
Accuracy in recognising happy facial expressions is associated with antidepressant response to a NOP receptor antagonist but not placebo treatment
(2021-10)
Background: Clinical trials with putative antidepressants can be difficult to execute as it can take up to 8 weeks before differences emerge between drug and placebo, and long expensive trials often fail. Implementation ...
No Association Between Amygdala Responses to Negative Faces and Depressive Symptoms: Cross-Sectional Data from 28,638 Individuals in the UK Biobank Cohort
(2022-07)
In this Priority Data Letter, we report on the largest study to date to test the association between amygdala reactivity and depressive symptoms based on UK Biobank data. For transparency, we initially set out to investigate ...
