Such separation may enhance cognition, but in order to combine information processed by different sides and to obtain a complete understanding of the environment, information exchange between the hemispheres is essential. Martina Manns and Julianne Römling of Ruhr-University of Bochum (Germany) investigated hemispheric specialization and cooperation in the domestic pigeon (Columba livia).
