Individual action potentials in axons can be detected in vitro using intrinsic optical signals. The principles of this detection technique are described here. The technique has been demonstrated using neuronal axons dissected from lobster. It would also be applicable to axons and active dendrites of cultured neurons with diameters somewhat larger than an(More)
The detection of individual action potentials in nerve cells via intrinsic optical signals could open a new modality for the analysis of cellular properties in spatially extended cells and emergent properties in networks of neurons. Here we review the experimental evidence for the detection of changes in intrinsic optical properties, i.e., changes in(More)
