Neurons recruited in the nidopallium caudale, following changes in social environment, derive from the same original population.

Previously, we found that new neurons recruited into the nidopallium caudale in isolated birds were less labeled than those of communally housed birds, suggesting that different types of neurons may survive best under different conditions. Repetition of the experiment revealed no differences between groups, indicating that the new neurons were of the same generation. Hence, social environment does not appear to affect the type of newly recruited nidopallium caudale neurons.
