A new simultaneous 1020-site optical recording system for monitoring neural activity using voltage-sensitive dyes

We have constructed a new 1020-site optical system for simultaneous recording of transmembrane electrical activity, using a 34 x 34-element photodiode array. This new apparatus permits analyses of the spatio-temporal pattern of neural activity, such as action potentials and postsynaptic potentials, in the central nervous system, at higher spatial and temporal resolutions.
