Optical recording of neuronal activity in an invertebrate central nervous system: simultaneous monitoring of several neurons. Academic Article uri icon


  • 1. Using an optical method for measuring membrane potential, we have been able to monitor action-potential activity simultaneously in 14 neurons of the supraesophageal ganglion of the barnacle. 2. Under favorable conditions, 4-mV synaptic potentials could also be detected optically.
