Highlighted Application


Data from Dr. Corey Acker (1), showing a mouse pyramidal neuron loaded with ElectroFluor530sTM, and an optical voltage recording from a single dendritic spine. This more soluble version of ElectroFluor530 allows loading of individual neurons through the patch pipette, making it possible to do voltage recordings from spines and axons.
