Nat Commun
. 2024 Sep;
15(1):7827.
PMID: 39244544
The ability to switch between rules associating stimuli and responses depend on a circuit including the dorsomedial prefrontal cortex (dmPFC) and the subthalamic nucleus (STN). However, the precise neural implementations...

Nat Commun
. 2024 Aug;
15(1):7508.
PMID: 39209840
Neural activity within the ventromedial prefrontal cortex (vmPFC) and anterior insula (aIns) is often associated with economic choices and confidence. However, it remains unclear whether these brain regions are causally...

PMID: 38941238
How human prefrontal and insular regions interact while maximizing rewards and minimizing punishments is unknown. Capitalizing on human intracranial recordings, we demonstrate that the functional specificity toward reward or punishment...

Front Neurosci
. 2024 Mar;
18:1257579.
PMID: 38456146
Deep brain stimulation of the subthalamic nucleus (STN) has become the gold standard surgical treatment for Parkinson's disease and is being investigated for obsessive compulsive disorders. Even if the role...

Valdebenito-Oyarzo G, Martinez-Molina M, Soto-Icaza P, Zamorano F, Figueroa-Vargas A, Larrain-Valenzuela J, et al.
PLoS Biol
. 2024 Jan;
22(1):e3002452.
PMID: 38198502
Humans often face the challenge of making decisions between ambiguous options. The level of ambiguity in decision-making has been linked to activity in the parietal cortex, but its exact computational...

Collomb-Clerc A, Gueguen M, Minotti L, Kahane P, Navarro V, Bartolomei F, et al.
Nat Commun
. 2023 Oct;
14(1):6534.
PMID: 37848435
Reinforcement-based adaptive decision-making is believed to recruit fronto-striatal circuits. A critical node of the fronto-striatal circuit is the thalamus. However, direct evidence of its involvement in human reinforcement learning is...

J Affect Disord
. 2023 Aug;
340:694-702.
PMID: 37591352
Background: Reward sensitivity is an essential dimension related to mood fluctuations in bipolar disorder (BD), but there is currently a debate around hypersensitivity or hyposensitivity hypotheses to reward in BD...

JAMA Psychiatry
. 2023 Apr;
80(6):548-557.
PMID: 37043223
Importance: Motivational impairments in schizophrenia are by definition associated with poor outcome. It is postulated that the reduction of goal-directed behavior arises from abnormal trade-offs between rewards and efforts. Objective:...

Trials
. 2023 Feb;
24(1):141.
PMID: 36829240
Background: In parallel to the traditional symptomatology, deficits in cognition (memory, attention, reasoning, social functioning) contribute significantly to disability and suffering in individuals with schizophrenia. Cognitive deficits have been closely...

Intracerebral mechanisms explaining the impact of incidental feedback on mood state and risky choice
Cecchi R, Vinckier F, Hammer J, Marusic P, Nica A, Rheims S, et al.

PMID: 35822700
Identifying factors whose fluctuations are associated with choice inconsistency is a major issue for rational decision theory. Here, we investigated the neuro-computational mechanisms through which mood fluctuations may bias human...
