Abstract

Major advances in neuroscience have often followed directly from the application of new and more powerful methodological approaches to the study of brain structure and function (Clarke & Jacyna, 1987). Within the last decade a new technique has been developed that allows both brain structure and function to be studied in a closely integrated and highly complimentary fashion. This technique is multiple-site optical recording of membrane potential, or more simply, optical recording. Optical recording is based upon the ability of certain vital dyes (potentiometric probes) to optically signal changes in intracellular membrane potential. By viewing brain tissue stained with a voltage-sensitive dye with a suitable light detector system, changes in neuronal activity can be monitored simultaneously from a 100 or more contiguous anatomical regions (cf. Grinvald et al., 1988).
