Een beeldvormende techniek voor de monitoring van membraanpotentiaal verandert met sub-micrometer ruimtelijke en minder dan een milliseconde tijdsresolutie wordt beschreven. De techniek is gebaseerd op laser-excitatie van voltage-sensitieve kleurstoffen, maakt metingen van signalen in de axonen en axon collateralen, terminal dendritische takken, en individuele dendritische spines.
