Preclinical 1H MRS Study of a Porcine Model Shows Evidence and Mechanisms for Acute Neuronal Injury in Neonatal Cardiopulmonary Bypass (CPB) Surgery

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 557-567, August 2026.
ABSTRACT Purpose Congenital heart disease affects 1% of US births, with some infants requiring cardiothoracic surgery under cardiopulmonary bypass (CPB). Optimal surgical parameters to minimize neuronal injury are unknown. We used serial 1H MRS in a neonatal CPB porcine model to assess acute neuronal damage and associated injury mechanisms.

Task‐Evoked Functional Activation and Coupling With CSF Flow Detected in the Human Brain With Ultrashort Echo Time fMRI at 7 T

NMR in Biomedicine, Volume 39, Issue 8, August 2026.
Ultrashort and zero echo time (UTE and ZTE) MRI techniques generate functional contrast through inflow effects, making them suitable for studying cerebral blood flow and cerebrospinal fluid (CSF) dynamics. In a 7‐T study of 13 participants performing a visual task, we demonstrate that UTE produced robust, reproducible activations with group‐level ...

Registered Clinical Trials of Ayahuasca and DMT: A Scoping Review

Clinical Pharmacology &Therapeutics, Volume 120, Issue 1, Page 94-108, July 2026.
Interest in ayahuasca and its main component, N,N‐Dimethyltryptamine (DMT), has currently moved from historical and experimental use into modern clinical development. Yet, current evidence is fragmented, and systematic mapping of trial methods and design choices remains limited.

The Human Dorsolateral Prefrontal Cortex in Pain and Pain Modulation: A Review and Activation‐Likelihood Estimation Approach

European Journal of Pain, Volume 30, Issue 6, July 2026.
ABSTRACT Background The dorsolateral prefrontal cortex (dlPFC) has become a cornerstone of pain neuroscience, believed critically involved in processing acute and chronic pain, as well as in pain modulation. The dlPFC is thought to balance sensory perception with the cognitive appraisal of noxious stimuli.

Clinically Feasible White Matter Fiber Tractography in Peritumoral Zones With Cerebral Vasogenic Edema

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 287-301, July 2026.
ABSTRACT Purpose In diffusion MRI, vasogenic edema manifests as a major fraction of isotropic water that dilutes the anisotropic intra‐axonal portion of the signal. Many tractography algorithms mistake vasogenic edema for the white matter boundary and terminate tracking to prevent producing spurious streamlines.
