A Long-Time, High Spatiotemporal Resolution Optical Recording System for Membrane Potential Activity via Real-Time Writing to the Hard Disk
J Physiol Sci Vol.56, No.3 pp.263-266
Abstract: Using real-time hard disk recording, we have developed an optical system for the long-duration detection of changes in membrane potential from 1,020 sites with a high temporal resolution. The signal-to-noise ratio was sufficient for analyzing the spreading pattern of excitatory waves in frog atria in a single sweep.
