The Intrinsic Manifold of Spontaneous Activity Constrains Cortical Responses to Naturalistic Stimuli

This paper shows that the low-dimensional manifold of spontaneous brain activity can represent responses to naturalistic stimuli, using a deep variational autoencoder trained on resting-state fMRI data.

Image Processing in the Acute to Chronic Pain Signatures (A2CPS) Project

The paper describes the neuroimaging component of the A2CPS project, detailing data collection, processing, and initial findings linking brain measures to clinical variables.

Age-related differences in GABA: Impact of analysis technique

This study examines how different analysis techniques affect age-related differences in GABA concentrations, finding that tissue composition significantly influences results.

Neural Correlates of Working Memory Training: Evidence for Plasticity in Older Adults

This study shows that working memory training increases neural efficiency and shifts activation peaks towards higher loads in older adults, indicating functional plasticity.

Image processing and analysis methods for the Adolescent Brain Cognitive Development Study

The paper describes neuroimaging processing methods for the ABCD Study to extract brain phenotypes from multimodal imaging data.

Neural distinctiveness declines with age in auditory cortex and is associated with auditory GABA levels.

This study shows that older adults show less distinct neural activation patterns in auditory cortex and lower GABA levels, with GABA levels predicting neural distinctiveness in older adults.

Brain Connectivity Tracks Effects of Chemotherapy Separately from Behavioral Measures

The paper examines how chemotherapy affects brain connectivity and cognitive health, finding that functional connectivity changes are distinct from behavioral measures of cognitive performance.
