    Description

    Magnetic resonance imaging (MRI) can image brain structure non-invasively and without ionizing radiation. However, inferring histopathological information from MRI remains challenging due to lack of direct links between MRI signals and cellular structures. This study showed that deep convolutional neural networks can estimate histological staining intensity directly from MRI signals developed using...

    Description

    Synaptic vesicles (SVs) play a key role in synaptic transmission. This study used time-lapse microscopy to demonstrate two distinct mechanisms of vesicle traffic along axons. They employed specific pharmacological interventions along with imaging of transient actin polymerization and traffic of recycling SVs loaded with single quantum dots to characterize the underlying axonal actin structures. For...

    Description

    This study demonstrated that time-dependent diffusion MRI can detect subtle axonal changes in brain injury by identifying structural signatures of diffusive dynamics of water along axons. Scattering theory reveal two parameters that determine the diffusive dynamics of water along axons: the average reciprocal cross-section and the variance of long-range cross-sectional fluctuations. This theoretical...
