متن کاملPutative Adult Neurogenesis in Old World Parrots: The Congo African Grey Parrot (Psittacus erithacus) and Timneh Grey Parrot (Psittacus timneh)
In the current study, we examined for the first time, the potential for adult neurogenesis throughout the brain of the Congo African grey parrot (Psittacus erithacus) and Timneh grey parrot (Psittacus timneh) using immunohistochemistry for the endogenous markers proliferating cell nuclear antigen (PCNA), which labels proliferating cells, and doublecortin (DCX), which stains immature and migrati...
متن کاملSocial context influences the vocalizations of a home-raised African Grey parrot (Psittacus erithacus erithacus).
Home-raised African Grey parrots (Psittacus erithacus erithacus) exhibit strong social bonding with their human companions.
