Despite suffering a stroke, children recover brain function of the affected area
Given the laterality shown by human beings, each brain hemisphere specializes in a number of functions. For example, language is usually focused in the left hemisphere and perception in the right. Children who suffer prenatal or perinatal brain injury with brain haemorrhage develop notable normal cognitive functions in certain areas such as those associated with language skills. One possible explanation for this has been that the brain regions of the unaffected brain hemisphere could replace the functions of the damaged counterpart.
But neurologists find it difficult to determine, after a brain injury, whether changes in neuronal activity are due to damage caused by the injury itself or caused by processes related with the reorganization of the brain after the injury.
A study just published in The Journal of Neuroscience aims precisely to ascertain this. The study was directed by Gustavo Deco, ICREA research professor and director of the CBC, involving Mohit Adhikari, member of the group and first author of the article, together with researchers from Canada, the USA and Switzerland (upf.news)
