From RIKEN Research:
Scientists from RIKEN Brain Science Institute in Wako, Japan and the Institute of Neurology at University College London have discovered that the brains of macaque monkeys undergo significant development when they are taught how to use tools. This finding may imply that our advanced human brains got as big and powerful as they did thanks to using tools, rather than the other way around.
The researchers used a technique called voxel-based morphometry (VBM) to classify areas of brain tissue in their MRI images as grey matter, white matter, or cerebro-spinal fluid, and to compare the volume of each tissue at different stages of learning. Read more »
