what is  canary forebrain?

The connection of neurons born in adult canary forebrain was determined using thymidine autoradiography and retrograde transfer of horseradish peroxidase (HRP).

Neurons in a forebrain nucleus, hyperstriatium ventralis, pars caudalis (HVc), were tagged 30 or 60 days later by retrograde transfer of HRP injected into the only two nuclei known to receive a projection from HVc: robustus archistriatalis (RA) and area X of lobus parolfactorius.

Thymidine tagged more than 9% of all neurons in HVc.
