Expected reward value and reward prediction errors reinforce but also interfere with human time perception.

This study shows that expected reward value and reward prediction errors affect human performance in judging 1000ms time intervals but not longer intervals.

Dopamine and serotonin transients predict depressive symptom relief following deep brain stimulation of human subcallosal cingulate cortex

This paper shows that dopamine and serotonin changes during deep brain stimulation predict symptom relief in treatment-resistant depression.

Striatal dopamine modulates reward-reinforced temporal learning in humans.

This study investigates how rapid dopamine changes in the striatum affect temporal learning in humans during interval timing tasks with and without monetary reinforcement.

Sub-second fluctuations in extracellular dopamine encode reward and punishment prediction errors in humans

The paper shows that extracellular dopamine in human striatum encodes both reward and punishment prediction errors through separate pathways during a learning task.

Sub-second Dopamine Signals during Risky Decision-Making in Patients with Impulse Control Disorder

This study measures sub-second dopamine signaling in patients with and without impulse control disorder during risky decision-making, finding increased risky behavior and exaggerated dopamine responses in those with ICD.

Time perception reflects individual differences in motor and non-motor symptoms of Parkinson's disease

The paper quantifies how time perception varies with motor and non-motor symptoms in Parkinson's disease, linking these differences to dopaminergic mechanisms.

Valence-partitioned learning signals drive choice behavior and phenomenal subjective experience in humans

This paper introduces a valence-partitioned reinforcement learning model that predicts human choice behavior, subjective experience, and BOLD responses by processing reward and punishment independently.

Acute hyper- and hypoglycemia uncouples the metabolic cooperation between glucose and lactate to disrupt sleep

This study shows that acute hyper- and hypoglycemia disrupt the metabolic cooperation between glucose and lactate in the brain, affecting sleep-wake cycles.

Hierachical Resampling for Bagging in Multi-Study Prediction with Applications to Human Neurochemical Sensing

The paper introduces a hierarchical resampling method for multi-study prediction, showing improved performance in neurochemical sensing applications.

A Dynamic Affective Core to Bind the Contents, Context, and Value of Conscious Experience

The paper reviews the challenges in understanding conscious experience and proposes a Dynamic Affective Core Hypothesis integrating affective value with neural representations.

Random burst sensing of neurotransmitters

This paper introduces a random sensing method for detecting neurotransmitters and pH, achieving fast, high-quality estimates with potential for significant speedups.
