Corticoid complex, a part of avian brain, has been suggested to play an important role in emotion, cognition and memory. It has been divided into intermediate corticoid area and dorsolateral corticoid area. The seasonal oscillations in the spaces between neurons have been taken into consideration, and it was observed that spaces between neurons, i.e. neuronal spacing in corticoid complex of female Indian ring-neck parrot (Psittacula krameri), significantly accredited during breeding time of bird. The result obtained in the present study as well as the previous studies highlighting other adjacent regions of brain (hippocampal complex) suggest better functioning and networking of the region concerned during active or breeding time of bird.
