Ferumoxytol-enhanced MRI enables high-resolution, laminar mapping of cerebral blood volume in the primate brain, validating core neurovascular features and advancing noninvasive tools for neurometabolic imaging.
A dynamic DNA methylation 'barcode' on the X chromosome can distinguish thousands of individual adult male neurons and may record aspects of their development.
A temporally stable and cell-type-specific genetic driver library provides the means to access and manipulate neuronal lineages in the fly nervous system during development and adulthood.
