Interpretable and Brain-Inspired Recurrent Model of Hierarchical Decision-Making Capturing Trial-by-Trial Variability

The paper develops a neurocomputational model of hierarchical decision-making that captures trial-by-trial variability and reproduces human behavioral patterns.

Interpersonal alignment of neural evidence accumulation to social exchange of confidence

The paper investigates how shared and subjective uncertainty align during social interactions using neural and behavioral data, finding that social information modulates evidence accumulation and neural dynamics.

How spatial attention affects the decision process: looking through the lens of Bayesian hierarchical diffusion model & EEG analysis

This study uses a Bayesian hierarchical diffusion model and EEG analysis to show that spatial attention affects non-decision time in perceptual decisions, with contralateral N2 oscillations and non-decision times reflecting these effects.

Improvement of association between confidence and accuracy after integration of separate evidence over time

The paper shows that integrating evidence over time improves confidence-accuracy associations, with EEG and pupil responses reflecting this in double-pulse trials.

Excitatory Deep Brain Stimulation Quenches Parkinsonian Signs in the Basal Ganglia and Thalamus

This study uses a computational model of the basal ganglia to show that excitatory deep brain stimulation (EDBS) reduces pathological beta oscillations in Parkinson's disease, while inhibitory DBS does not.

Beyond Core Object Recognition: Recurrent processes account for object recognition under occlusion

The paper investigates object recognition under occlusion using MEG, behavioral data, and computational models, showing that recurrent processes are essential and that a local recurrent model explains human performance.

Spatiotemporal Analysis of Category and Target-related Information Processing in the Brain during Object Detection

This study uses EEG to track how category- and target-related information is processed in the brain during object detection, showing prefrontal areas initiate target-related processing which predicts behavioral performance better.

Modulation of high frequency by low-frequency Oscillations in the basal ganglia

The paper uses a network model to show that delta-band stimulation modulates beta-band activity in the basal ganglia through specific inhibitory and excitatory interactions.
