Study: Loss of Half the Brain Doesn’t Mean No Word, Face Contact

Researchers astounded: Contrary to theory, in a recent study, the single remaining brain hemisphere supported both word and face reading functions

Some children have half of their brains removed (hemispherectomy) to control massive seizures that would otherwise destroy the child’s whole brain. Specialists were surprised that the children functioned fairly normally — certainly compared to what would have been expected. A recent study of post-hemispherectomy patients has provided dramatic evidence of rewiring: An unprecedented study of brain plasticity and visual perception found that people who, as children, had undergone surgery removing half of their brain correctly recognized differences between pairs of words or faces more than 80% of the time. Considering the volume of removed brain tissue, the surprising accuracy highlights the brain’s capacity — and its limitations — to rewire itself and adapt to dramatic surgery or traumatic injury.

If you have a few minutes waiting in line, you can try various tests on the internet to help you “figure out the huge dilemma”: Are you left- or right-brained? Or, at least, “Which side of your brain is more dominant?” (in 30 seconds). Buzzfeed, more elaborately, offers a Triangle Test to reveal the dominant side. This stuff is fun (maybe). But should we take it seriously? No. Many of us have heard one version or another of the pop psych myth that the brain functions as two separate departments, logic (left) vs. creativity (right). The myth carries conversations and sells workshops, books and TV shows. In reality, the brain’s two hemispheres work together for most jobs, the degree of Read More ›
