This study investigates how different doses of ketamine affect functional connectivity in mice brains using fMRI and finds dose-dependent changes in connectivity patterns.

This study examines age-related changes in functional connectivity during the Stroop task using fMRI and Bayesian hierarchical modeling, finding reduced inter-subject similarity and specific spatial reorganization in older adults.

This paper presents a comparative MRI resource and analysis of 16 avian species, revealing mosaic brain evolution with region-specific structural and connectivity differences.

This study examines age-related changes in functional and structural networks in macaque monkeys, finding decreased structural connectivity and increased functional connectivity and amplitude of low-frequency fluctuations with age.

This paper demonstrates that zero-echo time (ZTE) imaging can map whole brain activity in mice without signal loss in the amygdala, showing acute and latent activation patterns following noxious stimulation.

This study combines rsfMRI and immunohistochemistry to show how whole-brain functional connectivity and EGR1 expression change during operant learning in mice.

The paper investigates interhemispheric functional connectivity during non-dominant hand movement in right-handed subjects using gPPI and GLM analyses, finding increased connectivity in motor-related regions during non-dominant hand movement.

This study compares static and dynamic functional connectivity in awake and anaesthetized mice using resting-state fMRI, finding widespread decreases in static connectivity and shifts to local cortical connections under anaesthesia.

This paper shows that BIN1 overexpression in mice leads to early structural and functional impairments in hippocampal pathways associated with Alzheimer's disease, independent of A-beta changes.

This study uses chemogenetic activation of striatal neurons combined with fMRI to show increased thalamic and bilateral cortical activity and gamma-band oscillations.

This study examines how inhibiting aquaporin-4 channels affects BOLD and diffusion fMRI responses in rat visual cortex, showing increased BOLD amplitude but no change in diffusion responses.

The paper uses diffusion MRI to show that inhibiting AQP4 reduces the Sindex and increases sADC in mouse brain regions, indicating astrocyte activity changes.
