Recent advances in Ca2+ imaging have given neuroscientists a tool to follow the activity of large numbers of individual neurons simultaneously in vivo in the brains of animals as they are presented with sensory stimulation, respond to environmental challenges, and engage in behaviors. The Ca2+ sensors used to transduce changes in cellular Ca2+ into changes in fluorescence must bind Ca2+ to produce a signal. By binding Ca2+, these sensors can act as buffers, often reducing the magnitude of a Ca2+ change several fold and producing a proportional slowing of the rates of change. Ca2+ probes can thus distort the patterns of activity they are intended to study and modify ongoing Ca2+ signaling functions. Recognizing these factors will enhance the use of in vivo Ca2+ imaging in the investigation of neural circuit function.
