This study shows that removing reinforcement in humans improves instrumental performance by reducing a general action bias, not by unmasking learned associations.

The paper examines brain activity in rats during rule shifts in a T-maze, identifying specific prefrontal and striatal regions activated during learning new reward contingencies.

The paper shows that strong neural representations of past task features can slow reaction times in future behavior during task-switching.

The paper investigates how task difficulty and reward affect task enjoyment and striatal activation, finding intrinsic motivation for near-impossible tasks without extrinsic rewards.

The paper uses high precision MEG to show R-IFG beta power increases during response conflict, suggesting a generalized role in response inhibition beyond simple stopping.

This paper conducts a meta-analysis of 77 MIDT studies to identify shared and distinct neural activity during anticipation and outcome of monetary wins and losses.

This study shows that the multiple-demand network processes task difficulty independently of context, using fMRI data from arithmetic tasks with varying difficulty levels.

This study develops a neurodynamical computational theory of action regulation and tests it in neurotypical individuals and Parkinson's disease patients, showing how disruptions in this mechanism lead to motor deficits.

This study uses EEG and drift-diffusion models to show spatial attention affects visual encoding time and non-decision processes in perceptual decision-making.

This study investigates how affect and neural activity influence the formation of self-efficacy beliefs through computational modeling and neuroimaging.

The paper investigates how monkeys switch between learned rules and continuously update them during a perceptual categorization task, revealing distinct computational processes for rule switching and rule learning.

The paper examines how changes in basal ganglia output, specifically in the substantia nigra pars reticulata, contribute to self-restraint during a behavioral inhibition task in rats.

The paper investigates how conjunctive representations support prioritization and selection of planned actions in working memory, showing that high-priority actions are more strongly represented and selected.

The paper provides electrophysiological normative responses for emotional images to create reliable probes for studying affective systems.

This study investigates striatal activity in rats during action sequence initiation, finding that adolescent rats show steeper modulation of striatal responses with waiting time compared to adults.

This paper derives a normative decision model that uses adaptive thresholds to maximize reward in changing environments, showing better performance than constant-threshold models.

The paper shows that amygdala activity biases perceptual decisions towards desired outcomes by enhancing sensory evidence processing during decision-making.

This study shows that pubertal maturation, not just chronological age, is more strongly linked to improvements in inhibitory control, particularly through changes in ventrolateral prefrontal cortex activation.

This study examines SSRT changes across two sessions of the anticipatory response inhibition task and stop signal task, finding stable non-selective inhibition but changes in partial inhibition.

This study shows that long-term training increases lPFC involvement in working memory by shaping stimulus-selective representations and sequence relationships, reconciling conflicting views on lPFC function.

This study shows that lateral OFC subpopulations encode current and prior action information, and their disruption affects action control and contingency reversal.

This study shows that human defensive neural circuits, not just empathy, drive helping behavior when others are in danger.

This study investigates exogenous attention to emotional facial expressions across menstrual cycle phases in women without PMS, finding no phase-emotion interaction in behavioral or ERP measures.

The paper investigates assumptions about parameter generalization and interpretability in reinforcement learning models across different tasks and participants.

This study shows that task prioritization affects EEG oscillations during task preparation, but not the decoding of task-specific information or attentional orienting.

This study identifies the basolateral amygdala and orbitofrontal cortex as necessary for reward-seeking guided by occasion setters, while the dorsal hippocampus is not involved.

The paper examines the relationship between midfrontal theta activity and memory of errors during a Flanker task, finding that theta increases with errors but does not predict subsequent memory.

This study uses computational models to show that the dorsal anterior cingulate cortex encodes action-value during emotion regulation, with implications for understanding affective processing and therapy strategies.

The paper investigates how lateral orbitofrontal cortex and basolateral amygdala influence sensitivity to delayed punishment during decision-making in rodents.

The paper shows that dlPFC activation during normative choices is better explained by evidence accumulation than self-control mechanisms.
