Preserved Intrinsic Neural Timescale Organization with Hierarchical Variation in Autism Spectrum Disorder

The paper examines intrinsic neural timescales in autism spectrum disorder and typically developed controls, finding preserved hierarchical organization but individual variability linked to sensory traits.

Computational Mechanisms of Neuroimaging Biomarkers Uncovered by Multicenter Resting-State fMRI Connectivity Variation Profile

The paper develops a method to profile resting-state fMRI connectivity variations to improve the reliability and generalizability of psychiatric disorder biomarkers across multiple centers.

Iron deposition and functional connectivity alterations in the right substantia nigra of adult males with autism

This study examines iron deposition and functional connectivity in the substantia nigra of adults with autism, finding increased iron and altered connectivity patterns associated with symptom severity.

Generalizable neuromarker for autism spectrum disorder across imaging sites and developmental stages: A multi-site study

This study develops a generalizable neuromarker for ASD across multiple sites and developmental stages, showing significant performance in adults, children, and adolescents.

Effects of upgrading acquisition-techniques and harmonization methods: A multi-modal MRI study with implications for longitudinal designs

This study evaluates the impact of MRI acquisition upgrades and harmonization methods on brain parameters, showing that harmonization reduces protocol effects but requires sufficient participants.

Depression-like state induced by low-frequency repetitive transcranial magnetic stimulation to ventral medial frontal cortex in monkeys

This study uses low-frequency rTMS on the ventral medial frontal cortex of monkeys to induce a depression-like state, showing behavioral and physiological changes that are reversed by ketamine.

White matter alterations in autism spectrum disorder and attention-deficit/hyperactivity disorder in relation to sensory profile

This study examines white matter abnormalities in ASD and ADHD using DTI and finds shared and distinct relationships between white matter and sensory profiles.

Cortical surface architecture endophenotype and correlates of clinical diagnosis of autism spectrum disorder

The paper identifies cortical sulcal depth as an ASD endophenotype and shows neural correlates for clinical diagnosis differ from this endophenotype when accounting for TD sibling differences.

Machine learning approach to identify resting-state functional connectivity pattern serving as an endophenotype of autism spectrum disorder

The paper uses machine learning to identify a resting-state functional connectivity pattern associated with autism spectrum disorder endophenotypes and links it to communication impairment severity.
