Talking to the Brain: Using Large Language Models as Proxies to Model Brain Semantic Features
We introduce a novel paradigm using LLMs to map the brain's semantic space with greater ecological validity. This provides a robust framework for integrating naturalistic fMRI data and reveals a hierarchically organized semantic similarity space across the cerebral cortex.

In-vivo high-resolution χ-separation at 7T
A recently introduced quantitative susceptibility mapping (QSM) technique, χ-separation, offers the capability to separate paramagnetic (χpara) and diamagnetic (χdia) susceptibility distribution within the brain. In-vivo high-resolution mapping of iron and myelin distribution, estimated by χ-separation, could provide a deeper understanding of brain ...

Time Distributed Classification of Alzheimer's Disease on MRI Scans
Longitudinal MRI‐derived cortical thickness slopes improved AD/CN discrimination. A time‐distributed 3D ResNet‐101 + LSTM further captured spatiotemporal progression, reaching 96.7% accuracy and also improving MCI‐related classification. ABSTRACT The diagnosis of Alzheimer's disease (AD) has progressively depended on sophisticated neuroimaging methods ...

Evaluation of an open-face 8-channel transmit 64-channel receive 7T head coil for neuroimaging
IntroductionUltra-high field (UHF) 7 tesla (7T) MRI offers unique diagnostic opportunities for clinical neuroimaging. However, broader clinical implementation remains limited because the reduced radiofrequency (RF) wavelength at 7T causes RF transmit ...
