4-Carboxymethoxy-5,7-Dinitroindolinyl-Glu: An Improved Caged Glutamate for Expeditious Ultraviolet and Two-Photon Photolysis in Brain Slices

Caged neurotransmitters are useful photochemical tools for selective stimulation of synapses and other transmitter receptors. Before illumination, the caged compound is biologically inert. Photolysis breaks a covalent bond, liberating the caged neurotransmitter. Release can be rapid, so the
