Dorsal Raphe VIP Neurons Are Critical for Survival‐Oriented Vigilance
Advanced Science, EarlyView.DRNVIP neurons in mice and primates are strategically positioned to influence the central extended amygdala via feedback loops. They regulate the excitability of PKC‐δ neurons in the ovBNST and CeA through glutamate release. Their ablation heightens activity in these regions, disrupts active‐phase sleep architecture, enhances risk assessment behaviors ...

Axonal transport versus dendritic transport
Journal of Neurobiology, 2003AbstractNeurons have polarized processes for information output and input, axons, and dendrites. This polarized architecture is essential for the neuronal function. An increasing number of molecular components that mediate neuronal polarity establishment have been characterized over the past few years.

Fast Axonal Transport in Squid Giant Axon
Science, 1982Video-enhanced contrast-differential interference contrast microscopy has revealed new features of axonal transport in the giant axon of the squid, where no movement had been detected previously by conventional microscopy. The newly discovered dominant feature is vast numbers of "submicroscopic" particles, probably 30- to 50-nanometer vesicles and ...

Current Biology, 1992
New studies provide further evidence that the neuronal cytoskeleton is the product of a dynamic interplay between axonal transport processes and locally regulated assembly mechanisms. These data confirm that the axonal cytoskeleton in mammalian systems is largely stationary and is maintained by a smaller pool of moving subunits or polymers. Slow axonal

Axonal transport in neuropathy
Muscle & Nerve, 1983AbstractRecent studies on the distribution of labeled endogenous proteins in the experimental neuropathies induced by streoptozotocin diabetes, galactose feeding, zinc pyridinethione, 2,5‐hexanedione, acrylamide, and p‐bromophenylacetylurea (BPAU) have demonstrated an impaired build up of retrogradely transported material derived from the more distal ...

Axonal transport—II. Convection
Bulletin of Mathematical Biology, 1976The phenomenon of axonal transport has been well documented (Ochs, 971; Lasek, 1970; and Grafstein, 1967). In a previous paper, we showed how diffusion alone could not account for this process. In this report we show that convection or convection with diffusion can account for the observed build-up of material.

Bulletin of Mathematical Biology, 1976
The phenomenon of axonal transport of material has been well documented (Ochs, 1971; Lasek, 1970; and Grafstein, 1967). This report seeks to establish the role of diffusion—if any—in such a transport process. We report that diffusion cannot account for the observed build-up of material as reported in the literature.

Axonal transport of lipid in goldfish optic axons
Neurochemical Research, 1978After injection of labeled glycerol, choline, or serine into the eye of goldfish, labeled lipids were axonally transported along the optic nerve to the optic tectum. Although the different precursors were presumably incorporated into somewhat different lipid populations, all three were approximately equally effective in labeling the lipids transported ...
