The human brain is often considered to be the most cognitively capable among mammalian brains and to be much larger than expected for a mammal of our body size. [...] Key Method Here we determine these numbers by using the isotropic fractionator and compare them with the expected values for a human-sized primate. We find that the adult male human brain contains on average 86.1 +/- 8.1 billion NeuN-positive cells ("neurons") and 84.6 +/- 9.8 billion NeuN-negative ("nonneuronal") cells. With only 19% of all…Expand Abstract
