摘要：

Optical imaging of electrical activity using voltage-sensitive dyes has been envisaged for many years as a powerful method to investigate multineuronal representation of information processing in brain tissue. This article describes the advent of novel genetically targeted voltage-sensitive fluorescent proteins. This new class of membrane voltage sensors overcomes previous limitations related to the nonselective staining of membranes associated with conventional voltage-sensitive dyes. Here, we discuss the methodology, applications, and potential advantages of this novel technique. (C) 2003 Elsevier Science (USA). All rights reserved.
