Enhanced Brain-Heart Connectivity as a Precursor of Reduced State Anxiety After Therapeutic Virtual Reality Immersion

The paper identifies biomarkers of anxiety reduction following a virtual reality intervention, showing increased midline beta power, heart rate variability, and brain-to-heart connectivity correlate with therapeutic response.

A structural MRI marker predicts individual differences in impulsivity and classifies patients with behavioral-variant frontotemporal dementia from matched controls

The paper develops a structural MRI signature of impulsivity using machine learning, validates it across multiple samples, and shows its diagnostic value in behavioral-variant frontotemporal dementia.

High delay discounting relates to core symptoms and to pulvinar atrophy in frontotemporal dementia

This study finds that frontotemporal dementia patients show higher delay discounting, linked to impulsivity symptoms and pulvinar atrophy.

Time course of EEG power during creative problem-solving with insight or remote thinking

This study examines EEG power changes during creative problem-solving, finding specific brain activity patterns linked to semantic remoteness and insight moments.

"A mosquito bites and a butterfly flies": a specific response type of frontal patients in a similarity task

The paper develops a verbal similarity task to differentiate frontal lobe patients from others, finding differentiation errors are specific to frontal patients.

Advanced Lesion Symptom Mapping Analyses And Implementation As BCBtoolkit

The paper develops methods to map lesion effects on brain circuits and shows they impact category fluency, with results available in BCBtoolkit.

Anterior temporal lobe morphometry predicts categorization ability

The paper investigates how morphometric differences in the anterior temporal lobe correlate with semantic and shape categorization performance in healthy controls.
