Effect of stimulation parameters for transcranial temporal interference stimulation to enhance occipital alpha-oscillations in healthy participants

This study investigates whether transcranial temporal interference stimulation (tTIS) modulates occipital alpha power compared to sham and carrier control, finding significant increases with tTIS.

Structural Connectivity Between the Locus Coeruleus and Nucleus Basalis of Meynert Relates to Dual-Task Performance

This study examines the relationship between structural connectivity between the locus coeruleus and nucleus basalis of Meynert and dual-task performance in younger and older adults.

Domain-Specific Functional Network Adaptations Supporting Dual-Task Performance in Older Adults

This study examines age-related changes in brain network connectivity during motor and cognitive tasks, finding domain-specific adaptations in older adults.

Longitudinal Observations of the Effects of Ischemic Stroke on Binaural Perception

This study tracks binaural perception changes in ischemic stroke patients over time, showing individual recovery patterns rather than consistent lesion-based effects.

Replicability, repeatability, and long-term reproducibility of cerebellar morphometry

This study evaluates the replicability, repeatability, and long-term reproducibility of three cerebellar morphometry tools using MRI data from different studies.

Model-based and model-free analyses of the neural correlates of tongue movements

This study uses fMRI to analyze cerebral control of tongue movements and inter-individual differences, finding distinct neural networks and activity patterns for different movement types.
