Abstract
The existence of gap junctions between cells is detected by stimulating the cells with electrical pulses having selective parameters and then detecting propagated signals emitted by the cells. A needle is provided having stimulation electrodes thereon from which the stimulating pulses emanate and an array of recording electrodes for detecting the pulses. In an alternative embodiment, an array of piezoelectric electrodes is distributed within the array of recording electrodes. The signals detected by the recording electrodes and piezoelectric electrodes are monitored by a recording device and stored within a computer.
