Neural mechanisms of self-conformity

This study investigates self-conformity and group conformity using neural activity and behavioral data, finding shared and distinct neural mechanisms for both.

Distinct roles of neuronal phenotypes during neurofeedback adaptation

The paper investigates single-neuron dynamics during neurofeedback adaptation in rhesus macaques, finding that inhibitory interneurons are more active and engaged in learning compared to excitatory pyramidal neurons.

Population-level constraints on single neuron tuning changes during behavioral adaptation

This study examines how individual neurons adapt during behavioral training and finds that neurons with strong population co-variation and prior behavioral contribution are less likely to change their activity.

Volitional Regulation and Transferable Patterns of Midbrain Oscillations

This paper demonstrates neurofeedback using VTA LFP signals in non-human primates, showing transferable control strategies and potential for clinical applications.

Social risk coding by amygdala activity and connectivity with dorsal anterior cingulate cortex

The paper examines how social risk affects neural activity in the amygdala and its connection to the dorsal anterior cingulate cortex in human volunteers.

Neural population variance explains adaptation differences during learning

The paper investigates how neural spiking variability affects adaptation during a brain-computer interface task in rhesus macaques, finding that population variance metrics differ between easy and hard adaptation conditions.

A Process Model Account of the Role of Dopamine in Intertemporal Choice

This paper presents a process model of dopamine's role in intertemporal choice, showing it affects both evidence accumulation and starting bias in decision-making.

Comparing adaptive coding of reward in bipolar I disorder and schizophrenia

The paper compares adaptive coding of reward in bipolar I disorder and schizophrenia, finding similar deficits in the right posterior caudate but more preserved coding in BD in anterior regions.

Learning from ingroup experiences changes intergroup impressions

The paper shows that ingroup experiences significantly influence intergroup impressions, with neural and computational evidence supporting ingroup-focused theories over outgroup-focused ones.

Cerebellar and cortico-striatal-midbrain contributions to reward-cognition processes and apathy within the psychosis continuum

The paper investigates neural correlates of reward-cognition interactions and apathy in the psychosis continuum using fMRI and clinical scores.

Opioid antagonism reduces wanting by strengthening frontostriatal connectivity

This study shows that opioid antagonism reduces reward wanting by enhancing frontostriatal connectivity in humans.

Neuro-Computational Foundations of Moral Preferences

This study challenges the common-currency hypothesis by showing distinct neural representations for moral and financial values in specific brain regions.

Neural codes in early sensory areas maximize fitness

This study shows that neural codes in early sensory areas prioritize fitness maximization over sensory accuracy, as demonstrated in blowfly retinas and human experiments.

Neural correlates of individual differences in aversion to risk and choice inconsistency

This study examines brain dynamics related to risk aversion and choice inconsistency using ERP recordings in a financial decision task.

Increased random exploration in schizophrenia is associated with inflammation

This study finds that schizophrenia patients show increased random exploration linked to inflammation and disorganization symptoms.

Neural Arbitration between Social and Individual Learning Systems

The paper investigates how people weigh self-gathered versus social information in decision-making using Bayesian models and fMRI, showing distinct brain regions for each type of information.

Individual differences in successful self-regulation of the dopaminergicmidbrain

This study examines how individual differences in self-regulation of the dopaminergic midbrain relate to cognitive control and reward sensitivity during neurofeedback training.

Sensitivity to gains during risky decision-making differentiates chronic cocaine users from stimulant-naive controls

This study finds that chronic cocaine users show altered sensitivity to gain information during risky decision-making, leading to increased risk-seeking in unfavorable scenarios.

Shared and dissociable features of apathy and reward system dysfunction in bipolar I disorder and schizophrenia

This study compares apathy and reward system dysfunction in bipolar I disorder and schizophrenia, finding comparable apathy severity but distinct neural correlates.

Motion and physiological noise effects on amygdala real-time fMRI neurofeedback learning

This study investigates how motion and physiological noise affect amygdala real-time fMRI neurofeedback learning and finds that these factors do not drive self-regulation learning.
