Temperature Dependence of Paramagnetic Species in the Human Brain Tissue: An X‐Band EPR Study

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Paramagnetic ions are distributed throughout the human brain. The increased accumulation of these metals, such as iron and copper, can induce cellular death and the development of neurological diseases. Electron Paramagnetic Resonance (EPR) is a spectroscopic technique capable of detecting these ions in a given biological sample ...

Magnetic Properties of Ferritin at Different Levels of Degradation: Implications for MRI‐Based Iron Quantification in the Brain

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Ferritin's iron core exhibits complex magnetic properties, as suggested by magnetometry and Mössbauer spectroscopy, which remain incompletely understood. In particular, the antiferromagnetic inner core could influence the accuracy of iron quantification using MRI and raise concerns about postmortem validation studies involving degraded

A unified 3D reconstruction of microscopy and MRI in a brain showing Alzheimer's disease‐related neuropathology

Brain Pathology, EarlyView.
Post mortem MRI was combined with neuropathological assessments at 600 μm intervals throughout the brain. Through this approach, a three dimensional account of an entire human brain with an intermediate Alzheimer's disease neuropathologic change was created.

Animal fluency in people with Parkinson's disease: Item‐based performance before and after deep brain stimulation surgery

Journal of Neuropsychology, EarlyView.
Abstract People with Parkinson disease (PD) after surgery for deep brain stimulation (DBS) of the subthalamic nucleus (STN‐DBS) often decline in animal fluency due to impairments in executive functions and/or language. Item‐based measures of animal fluency may shed light on the specific nature of this decline, and into the strategies used when ...

Chronic silencing of subsets of cortical layer 5 pyramidal neurons has a long‐term influence on the laminar distribution of parvalbumin interneurons and the perineuronal nets

Journal of Anatomy, Volume 246, Issue 4, Page 479-504, April 2025.
Chronic silencing of subsets of layer 5 projection neurons has distinct effects on the laminar distribution of PV interneurons and the perineuronal nets in the adult primary motor and somatosensory cortex. Abstract Neural networks are established throughout cortical development, which require the right ratios of glutamatergic and GABAergic neurons ...
