Optical Recording of Neuronal Activity: Parallel Versus Serial Methods
Optical recording of neural activity using voltage-sensitive dyes has become a powerful tool in the investigation of complex neuronal networks, from invertebrate ganglia to intact primate cortex. By this method, complementary to classical electrophysiological techniques, optical parameters that are related to membrane potential are monitored, thus enabling non-invasive, quasi-intracellular recording from multiple sites (for reviews see: Blasdel, 1989; Cohen et al., 1989; Cohen and Lesher, 1986; Grinvald, 1985; Lieke et al., 1989; Salzberg, 1983, 1989).
