Uncovering dynamic human brain phase coherence networks

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.

Psilocybin acutely reduces low-frequency BOLD power and frequency-specific connectivity

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

Pitfalls of mapping functional and molecular human brain imaging data from separate cohorts

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

Connecting the Dots: Approaching a Standardized Nomenclature for Molecular Connectivity Combining Data and Literature

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

Prediction of brain age using structural magnetic resonance imaging: A comparison of accuracy and test-retest reliability of publicly available software packages

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

The association between brain serotonin 2A receptor binding and neuroticism in healthy individuals: A Cimbi database independent replication study

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.

Synaptic density and neuronal metabolic function measured by PET in the unilateral 6-OHDA rat model of Parkinson's disease

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.

Psilocybin-induced changes in brain network integrity and segregation correlate with plasma psilocin level and psychedelic experience

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

Lasting effects of a single psilocybin dose on resting-state functional connectivity in healthy individuals

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.

Dorsal striatal dopamine induces fronto-cortical hypoactivity and implies reduced anxiety and compulsive behaviors in rats

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.
