Comments p.2004 left column top paragraph:"Within the liter and a half of human brain, stereologic studies estimate that there are approximately 20 billion neocortical neurons, with an average of 7,000 synaptic connections each (primary source)." See Duning T et al., 2005, PMID 15699394 p.549 right column top paragraph: "Given a total brain volume of 1,450 mL, decreases of ∼0.60% would correspond to a change of ∼−8.7 mL in brain volume, and an increase of 0.72% after severe fluid intake leads to an increase of ∼+10.4 mL."
