The Human Brain Has Neural Networks Not Found in Lab Mice

They are complex special networks whose purpose is silencing other neurons

Assuming that human brains and lab mouse brains work roughly the same is fine for many purposes. Even though the human brain has a thousand times more neurons, it must does many of the same basic things for the body as a mouse brain. But studying mouse brains won’t tell us what human brains do besides that. Moritz Helmstaedter of the Max Planck Institute for Brain Research in Frankfurt, asks a telling question: “So, is it primarily the fact that our brains are 1,000-fold larger, house 1000-fold more nerve cells that allows us to play chess and write children’s books, which mice arguably cannot do?” In a just-published study that he led, the researchers examined human tissue removed by neurosurgeons…
