The powerful computational operation of sequence recognition on behavioral timescales of approximately 1 s may emerge from synaptic activity-triggered build-up of biochemical waves in short 20 micron zones on dendrites.
Embryo-wide quantitative analysis of BMP signaling in zebrafish embryos, combined with a mathematical model-based computational screen, challenges the prevailing model of an antagonist counter-gradient shaping the gastrula BMP morphogen gradient and supports an antagonist sink with BMP diffusion mechanism.
The SCHENGEN3 protein is needed for the progression of isolated microdomains into a continuous band, which is necessary for the establishment of the major extracellular diffusion barrier in plant roots: the Casparian strip.
In vivo quantitative analysis of multi-shell diffusion MRI reveals novel insights into microstructure of human insular cortex and its functional circuits associated with the salience network and cognitive control.
Low-field single-sided magnetic resonance diffusion methods detect and measure permeability of sub-micron compartments which likely include cell processes, organelles, and cellular vesicles within ex vivo mouse spinal cords.
Mice exposed to complex early adversity show similar diffusion MRI changes to those reported in humans and sex-specific changes in connectivity that differentially affect contextual deficits in males and females.
