Magnetic resonance in medicine, 73(3), 1075-1084 (2014-04-12)
An acquisition method that does not increase scan time or specific absorption rate is investigated for reducing the deleterious effects of cerebrospinal fluid (CSF) partial volume effects on diffusion tensor imaging (DTI) tractography. It is based on using a shorter

Nanoparticles in contact with cells and living organisms generate quite novel interactions at the interface between the nanoparticle surface and the surrounding biological environment. However, a detailed time resolved molecular level description of the evolving interactions as nanoparticles are internalized

The visual cortex is organized into discrete domains characterized by their specific function, connectivity, chemoarchitecture, and cytoarchitecture. Gradients of transcription factors across the anteroposterior and mediolateral axes of the neocortex have previously been demonstrated to specify the main sensory regions.
