Decodability of Reward Learning Signals Predicts Mood Fluctuations
Sign Up to like & getrecommendations! Published in 2018 at "Current Biology"
DOI: 10.1016/j.cub.2018.03.038
Abstract: Summary Our mood often fluctuates without warning. Recent accounts propose that these fluctuations might be preceded by changes in how we process reward. According to this view, the degree to which reward improves our mood… read more here.

DOI: 10.1016/j.dcn.2018.12.006
Abstract: The brain is adapted to learn from interactions with the environment that predict or enable the procurement of rewards (Schultz, 2010). For infants, the main caregiver (often the mother) is most associated with primary biological… read more here.

DOI: 10.1016/j.schres.2019.10.019
Abstract: Patients with a disorder in the schizophrenia spectrum (SZ) demonstrate impairments in reward learning. A reduced sensitivity to social reward may impede social beyond non-social reward learning mechanisms. The aim of the current study was… read more here.

Reward learning deficits in Parkinson's disease depend on depression
Sign Up to like & getrecommendations! Published in 2017 at "Psychological Medicine"
DOI: 10.1017/s0033291717000769
Abstract: Background Depression is one of the most common and debilitating non-motor symptoms of Parkinson's disease (PD). The neurocognitive mechanisms underlying depression in PD are unclear and treatment is often suboptimal. Methods We investigated the role… read more here.

DOI: 10.1017/s0033291721005493
Abstract: BACKGROUND The serotonin (5-HT) hypothesis of anorexia nervosa (AN) posits that individuals predisposed toward or recovered from AN (recAN) have a central nervous hyperserotonergic state and therefore restrict food intake as a means to reduce… read more here.

DOI: 10.1017/s0033291723000478
Abstract: BACKGROUND Adolescent internalizing symptoms and trauma exposure have been linked with altered reward learning processes and decreased ventral striatal responses to rewarding cues. Recent computational work on decision-making highlights an important role for prospective representations… read more here.

DOI: 10.1038/s41467-022-28549-5
Abstract: Cap-adjacent nucleotides of animal, protist and viral mRNAs can be O -methylated at the 2‘ position of the ribose (cOMe). The functions of cOMe in animals, however, remain largely unknown. Here we show that the… read more here.

T164. NETWORK CONNECTIVITY SUPPORTING REWARD LEARNING DIFFERENTIALLY DISRUPTED IN TREATMENT RESISTANT SCHIZOPHRENIA
Sign Up to like & getrecommendations! Published in 2020 at "Schizophrenia Bulletin"
DOI: 10.1093/schbul/sbaa029.724
Abstract: Abstract Background It is estimated that one third of patients with schizophrenia fail to adequately respond to antipsychotic medication, termed ‘treatment-resistance’. This occurs despite adequate blockade of D2 receptors in the brain. The parsimonious options… read more here.

DOI: 10.3389/fnhum.2017.00648
Abstract: Sleep helps to protect and renew hippocampus-dependent declarative learning. Less is known about forms of learning that mainly engage the dopaminergic reward system. Animal studies showed that exogenous melatonin modulates the responses of the dopaminergic… read more here.
