Mouse hippocampal glial cell (organotypic slice) expressing the optical redox-sensor roGFP1

Cultured rat hippocampal neuron expressing the voltage-sensitive optical probe hVOS. Fluorescence donor of this hybrid FRET construct is a membrane-anchored eGFP

Cultured rat hippocampal astrocyte labeled with JC-1. The ratio of red and green JC-1 fluorescence, reports the mitochondrial polarization. Red-yellow colors indicate a high degree of polarization, blue/green colors represent weak polarization
