This paper introduces a mixture modeling approach to analyze brain phase coherence networks from fMRI data, identifying recurring synchronized activity states across cognitive tasks without task labels.

This study shows psilocybin reduces low-frequency BOLD power and alters frequency-specific connectivity in the brain.

The paper shows that estimating correlations across brain regions from separate cohorts can be misleading due to biases and errors in interpretation.

The paper introduces a standardized nomenclature for PET-based molecular connectivity and covariance to improve reproducibility and interpretation across imaging modalities and radiotracers.

This study compares six brain age prediction software packages using MRI data, finding pyment and brainageR to be most accurate and reliable.

This study replicates a positive association between serotonin 2A receptor binding and inward facets of neuroticism using the [11C]Cimbi-36 tracer and finds no moderating effect of cortisol awakening response.

This study compares [11C]UCB-J and [18F]FDG PET in a 6-OHDA rat model of Parkinson's disease, finding divergent changes in synaptic density and metabolic function in CSTC circuits.

This study shows that psilocin levels and subjective drug intensity correlate with changes in brain network integrity and segregation after psilocybin administration.

This study examines changes in resting-state functional connectivity after a single psilocybin dose in healthy individuals, finding decreased executive control network connectivity at one-week and a link to increased mindfulness at three-months.

The paper investigates the effects of dorsal striatal dopamine activation on CSTC circuit function in rats, finding reduced fronto-cortical activity and changes in behaviors related to anxiety and compulsive actions.
