Early human brain development can be greatly modified by environmental factors

This 2014 Brazilian human study found that the brains of people born without the corpus callosum, the major connection between brain hemispheres, adapted to this loss:

“The authors believe that the development of alternative pathways results from the brain’s ability for long-distance plasticity and occurs in the utero during embryo development, which indicates that connections formed in the human brain early in development can be greatly modified, and most likely by environmental or genetic factors.”

BRAVO! MORE STUDIES LIKE THIS ONE!

People have limited capability to adapt later in life to corpus callosum injuries or to brain hemisphere disconnection.
