Data represent mean numbers (± SEM) of npf transcript-expressing neurons per brain lobe. Data in parentheses indicate numbers of brain lobes examined. ND, not determined.
*Numbers in males are significantly greater than those in females (t test, P < 0.0001).
†These counts were performed for XX tra1 pseudomales.
