The Impact of Instrumental Music on Dual-task Interference in a Simulated Driving Environment

This study examines how instrumental music affects dual-task performance in a simulated driving environment, finding that music can improve accuracy without increasing reaction time, especially with a 600 ms task gap.

Prefrontal cortex temporally multiplexes slow and fast dynamics in value learning and memory

The paper identifies a two-rate system in vlPFC neurons that temporally multiplex slow and fast dynamics during value learning and memory, leading to spontaneous recovery of old values.

Individual differences in sequential decision-making

The paper identifies a dominant nonlinear axis of individual variability in decision-making tasks, showing that exploration tendency, rather than personality or learning parameters, drives differences in performance.

Spatially Enhanced Processing for Valuable Objects in Prefrontal Cortex Neurons During Efficient Search

The paper shows that during efficient visual search for high-value objects, vlPFC neurons exhibit enhanced processing of peripheral targets, correlating with improved detection.

Value-based search efficiency is encoded in substantia nigra reticulata firing rate, spiking irregularity and local field potential

The paper shows that efficient value-based visual search is associated with specific firing rate, spiking irregularity, and LFP patterns in SNr neurons during target detection.

The Temporal Profile of Dual-task Interference in the Human Brain

The paper investigates dual-task interference in the human brain using EEG, MVPA, and DDM, finding increased reaction times and reduced decoding accuracy in short SOA conditions.

Prefrontal Cortex Encodes Value Pop-out in Visual Search

The paper shows that the ventrolateral prefrontal cortex (vlPFC) encodes value pop-out during visual search, with neural activity predicting search efficiency.

Disturbance of Information in Superior Parietal Lobe during Dual-task Interference in a Simulated Driving Task

The paper uses MVPA to show that dual-task interference in simulated driving disrupts information processing in the superior parietal lobe, correlating with slower reaction times.

Pupil size predicts the onset of exploration and changes in prefrontal dynamics

The paper shows pupil size predicts exploration onset and prefrontal neural changes in rhesus macaques during decision-making.

Effect of MIND Diet Intervention on Cognitive Performance and Brain Structure in Healthy Obese Women: A Randomized Controlled Trial

This study investigates the effect of a MIND diet on cognitive performance and brain structure in healthy obese women, finding improvements in memory and attention and changes in brain morphology.

Coordinated multivoxel coding beyond univariate effects is not likely to be observable in fMRI data

The paper argues that significant MVPA results in fMRI do not necessarily indicate coordinated multivoxel coding, as higher-order statistics between voxels are unlikely to be observed due to hemodynamic and resolution limitations.

Dual-task Interference in a Simulated Driving Environment: Serial or Parallel Processing?

This study investigates dual-task interference in a simulated driving environment, finding that tasks are processed in a partial-parallel manner.
