Figure 10. Multi-unit efferent and afferent activity recorded in the distal (A and C) and proximal (B and D) VGV in response to moderate (1 ml) gastric distention.

A and B illustrate recordings from individual experiments in each branch. C and D illustrate the aggregate multi-unit responses. Moderate gastric distention caused a significant increase in proximal VGV afferent activity, proximal VGV efferent activity, and distal VGV afferent activity, but not in distal VGV efferent activity.
