A quantitative analysis of glucose-dependent transport regulation indicates that mitochondrial accumulation in regions of high nutrient availability can enhance metabolism in neuronal axons under physiologically relevant conditions.
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.
The diffusion coefficients of proteins in the cytoplasm depend on their net charge and the distribution of charge over the protein surface, with positive proteins moving up to 100-fold slower because they bind to ribosomes.
A series of quantitative behavioural and opto-physiological analyses using a novel robot microscope system reveals that C. elegans computes the time-differential and time-integral of sensory information for decision-making during olfactory navigation.
Neuronal participation in generation of motor patterns in the spinal circuits is lognormal, which is an indication of a rich diversity of activity within the mean-driven as well as the fluctuation-driven regimes.
