Abstract: The present invention provides, in part, platforms for analyzing an aspect of synaptic vesicle cycling. According to other aspects, the invention provides neuronal cell culture platform and platforms for analyzing an aspect of synaptic vesicle cycling. According to other aspects, the invention provides methods of measuring an aspect of synaptic vesicle cycling in a plurality of cells. According to other aspects, the invention provide methods for identifying a test agent as a modulator of an aspect of synaptic vesicle cycling.

Abstract: An isolated nucleic acid reporter construct, the protein for which it encodes and methods for its use for the in vivo or in vitro measurement of the concentration of a specific biologically important molecule in a subcellular compartment or locale are provided. Certain constructs described are useful in measuring the local concentration of ATP at synapses.

Abstract: An open bottomed wheeled carriage has upstanding side plates between which a flexible mat is dragged over the ground. The front end only of the mat is secured to a cross bar on the carriage at a height greater than that of a golf ball on the ground. The mat is made up of pivotally joined rings or rings and links or parallel chains so that balls on the ground over which the mat is pulled will pass upwardly through the rings or between links or chains to the upper surface of the mat. A cleated endless belt, driven by the carriage supporting ground wheels, sweeps the balls rearwardly over the mat into a container on the rear of the carriage.
