Whenever we are doing something, one of our brain hemispheres is more active than the other one. However, some tasks are only solvable with both sides working together.
PD Dr. Martina Manns and Juliane Römling of the Ruhr-Universität Bochum are investigating, how such specializations and co-operations arise. Based on a pigeon-model, they are proving for the first time in an experimental way, that the ability to combine complex impressions from both hemispheres, depends on environmental factors in the embryonic stage. (…)
First the pigeons have to learn to discriminate the combinations A/B and B/C with one eye, and C/D and D/E with the other one. Afterwards, they can use both eyes to decide between, for example, the colours B/D. However, only birds with embryonic light experience are able to solve this problem.

Imagine the smell of an orange. Have you got it? Are you also picturing the orange, even though I didn’t ask you to? Try fish. Or mown grass. You’ll find it’s difficult to bring a scent to mind without also calling up an image. It’s no coincidence, scientists say: Your brain’s visual processing center is doing double duty in the smell department.
