Abstract :
A glass multimicroelectrode system for simultaneous intracellular recordings in which four pieces of micropipettes with rectangular cross section are arranged in a square compartment is described. Techniques are outlined for fabricating such an eccentric micropipette. An example of simultaneous recordings of intracellular membrane potentials in the carp retina is demonstrated. A technique which would allow researchers to record from three or four neurons simultaneously is presented.
