Irimia, Chambers, Torgerson, and Van Horn (2012) provide a first-step graphic on how best to display connectivity findings, as is presented in Figure 13.15. This is referred to as a connectogram.
[...] the Aristotelian view that the soul resides primarily in the heart [...].
[...] the ways in which we think about [the brain] are much richer than in the past, not simply because of the amazing facts we have discovered, but above all because of how we interpret them.
As human's position changed and the manner in which the skull balanced on the spinal column pivoted, the brain expanded, altering the shape of the cranium.
despite the widespread quotes that the human brain contains 100 billion neurons and ten times more glial cells, the absolute number of neurons and glial cells in the human brain remains unknown. 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.
Four grams of glucose circulates in the blood of a person weighing 70 kg. This glucose is critical for normal function in many cell types. In accordance with the importance of these 4 g of glucose, a sophisticated control system is in place to maintain blood glucose constant. Our focus has been on the mechanisms by which the flux of glucose from liver to blood and from blood to skeletal muscle is regulated. ... The brain consumes ~60% of the blood glucose used in the sedentary, fasted person. ... The amount of glucose in the blood is preserved at the expense of glycogen reservoirs (Fig. 2). In postabsorptive humans, there are ~100 g of glycogen in the liver and ~400 g of glycogen in muscle. Carbohydrate oxidation by the working muscle can go up by ~10-fold with exercise, and yet after 1 h, blood glucose is maintained at ~4 g.
Thus, the restorative function of sleep may be a consequence of the enhanced removal of potentially neurotoxic waste products that accumulate in the awake central nervous system.
