This study uses multimodal imaging to show ketamine increases glutamate in the ACC and alters brain network connectivity, suggesting potential long-term neuroplastic effects.

The paper shows that midlife path integration impairments predict Alzheimer's disease risk, independent of other cognitive tests.

This study compares methods to correct superficial bias in 7T Gradient-Echo fMRI data and finds that ratio of ROI means and Deming regression are most effective.

This study assesses the reproducibility of 7 Tesla fMRI hand digit representation across multiple sites and within sites, finding lower inter-site than intra-site reproducibility but overall feasibility for multi-site studies.

This study creates a probabilistic atlas of the human locus coeruleus using ultra-high field MRI, revealing spatial gradients and providing a resource for future research.

This study evaluates the reproducibility of 7T quantitative susceptibility mapping (QSM) and R2* at multiple sites using a harmonized protocol, finding improved consistency compared to 3T.

This study investigates how experience shapes perceptual decisions by examining plasticity in cortical layers using high-resolution fMRI and orientation discrimination training.

This paper compares fMRI analysis packages for autocorrelation modeling, finding AFNI outperforms FSL and SPM, and recommends improved pre-whitening and diagnostics for better reliability.
