Longitudinal functional connectivity during rest and task is differentially related to Alzheimer's pathology and episodic memory in older adults

The paper examines how changes in functional connectivity during rest and task relate to Alzheimer's pathology and episodic memory in older adults.

A distributed brain response predicting the facial expression of acute nociceptive pain

This study uses fMRI to show that existing pain neurosignatures cannot predict facial pain expressions, introducing a new FEPS that specifically captures the brain response to nociceptive pain.

Modulating Subjective Pain Perception with Decoded MNI-space Neurofeedback

This study uses real-time fMRI decoding to modulate pain-related brain patterns and shows that participants can down-regulate pain signatures, correlating with changes in perceived pain intensity.

Functional brain age prediction suggests accelerated aging in preclinical familial Alzheimer's disease, irrespective of fibrillar amyloid-beta pathology

The paper develops a model to predict brain aging from resting state fMRI and finds accelerated brain aging in preclinical Alzheimer's disease, independent of amyloid-beta pathology.

A molecular gradient along the longitudinal axis of the human hippocampus informs large-scale behavioral systems

The paper identifies a molecular gradient along the human hippocampus's longitudinal axis that correlates with distinct brain systems and behavioral functions.

Distinct changes in morphometric networks in aging versus Alzheimer’s disease dementia

The paper identifies distinct morphometric network changes in aging and Alzheimer’s disease, showing additive effects of aging and AD on GM loss, with unique whole-brain pattern variability in AD.

Identification of traits and functional connectivity-based neuropsychotypes of chronic pain

The paper identifies four chronic pain traits using clustering and network analyses, revealing stable neurotraits that categorize patients into distinct neuropsychotypes.

Brain and psychological determinants of placebo pill response in chronic pain patients

This study shows that placebo pill response in chronic pain patients depends on brain structure, functional connectivity, and psychological factors, with machine learning predicting response magnitude.
