M, Thrust after mount (mount + thrust); I, thrust with intromission (intromission + thrust); E, thrust with intromission followed by ejaculation (ejaculation + intromission + thrust); N, number of recorded neurons. Asterisks indicate that the number is significantly larger than chance level (5%, which is the type I error rate of the t test used for the comparisons) (χ2 test, p < 0.05).
