Vagal afferent activity in the nodose ganglion

Abstract

Using small micro-electrodes (2 - 4 μm), it was possible to record in the nodose ganglion the activity of most types of stretch fibres previously described (including the fast and slow adapting). Aortic depressor impulses were also recorded clearly and in addition, some probable venous and deflator discharges.These results were only obtained after much trouble; the method does not seem to oe as useful for the study of vagal afferent activity as had been hoped.
