From: Selective stimulation of the ferret abdominal vagus nerve with multi-contact nerve cuff electrodes
Experimental setup. In six ferrets, (a,b) a four-contact cuff electrode was wrapped around either the ventral or dorsal abdominal vagus nerve to deliver biphasic symmetric stimulus pulses, either between contacts 1 and 2 or 3 and 4. (b,c) A 32-channel microelectrode array (MEA) was inserted into the left or right nodose ganglion to record evoked responses to stimulation of either the ventral or dorsal abdominal vagus nerve.
