Activation of the following neurons in a wild-type XY fly should promote courtship:
A) olfactory receptor neurons that innervate the DA1 glomerulus.
B) projection neurons that innervate the DA1 glomerulus.
C) DC1 neurons in the lateral horn of the protocerebrum.
D) projection neurons that innervate the VL2a glomerulus.
E) All of the above

Question

Quizplus · Accepted Answer

ORNs that innervate the DA1 glomerulus express a receptor for cVa, a pheromone produced by males to inhibit male courtship of males or mated females. Activation of downstream DA1 projection neurons and DC1 neurons should also inhibit courtship. On the other hand, VL2a ORNs and PNs are activated by aromatic food odors that appear to promote courtship.
