Both brain halves vital for problem solving

Berlin : Whenever we are engaged in a task, one half of our brain is more active than the other -- but some problems require both halves to work together to find a solution. Researchers in Germany are investigating how such specializations and cooperations arise.

Based on a pigeon-model, Martina Manns and Juliane Romling of the Ruhr-Universität Bochum, in Germany, are proving for the first time experimentally that the ability to combine complex impressions from both halves depends on environmental factors in the embryonic stage, the journal Nature Communications reports.

Within the egg, bird embryos always turn their head in such a way that one eye is turned close to the eggshell, and the other one is covered by the body.

This causes an asymmetrical light stimulation, which influences developmental processes in both brain halves, according to a statement of Ruhr-Universität Bochum.

Manns uses this mechanism for her experiment. One group of embryos hatch in a lighted incubator, another one in complete darkness. The results show that information exchange is impaired without light-stimulation.

This research sheds light on the origin of communication processes in the brain. Developmental disorders like ADHD or autism are characterized by a deviating pattern between the two brain halves.

Therefore, there is a possibility that the results may help to understand those disorders and open the way for better therapeutic approaches.
