CQ2-Query.rq

# CQ2: What are all origins and destinations of neuron populations traveling through the vagus?
# Query for CQ2: This query returns any neuron population that has its origin (soma) located in 
# Region A, axon terminal or axon sensory terminal located in Region B, and axon located in nerve C, 
# where C is vagus nerve or its part.
