"In one of the experiments conducted in the NEURO programme, participants learned the name and/or purpose of 150 ancient tools. They had never heard these words before. The subjects' brain function was measured by means of magnetoencelography during the naming of the tools, both before and after the learning period.
The results show that the brain uses the same neural networks to process both familiar and newly learned words.
. . .
In other words, it seems that the processing of meanings in the brain differs essentially from the processing of names. On the other hand, the performance results indicated that new definitions were learned even faster than new names.
