Heat and light, being modes of motion, «phosphorescence» and «incandescence» are phenomena to which consciousness has been likened by the production - theory: «As one sees a metallic rod, placed in a glowing furnace, gradually heat itself, and — as the undulations of the caloric grow more and more frequent — pass successively from the shades of bright red to dark red (sic), to white, and develope, as its temperature rises, heat and light, — so the living sensitive cells, in presence of the incitations that solicit them, exalt themselves progressively as to their most interior sensibility, enter into a phase of erethism, and at a certain number of vibrations, set free (dégagent) pain as a physiological expression of this same sensibility superheated to a red - white.»

Overstreet - Wadiche and UAB colleagues posed a basic question: Since the number of neurons in the dentate gyrus increases by neurogenesis while the number of neurons in the cortex remains the same, does the brain create additional synapses from the cortical neurons to the new granule cells, or do some cortical neurons transfer their connections from mature granule cells to the new granule cells?

Second, the researchers theorized that if each cell was indeed responsible for coding only a single axis in face space, each cell should respond exactly the same way to an infinite number of faces that look extremely different but all have the same projection on this cell's preferred axis.

Immune cells that specialize in defending these areas may get some prompting from IL - 34, the researchers speculate, but the numbers of these cells were not significantly reduced when IL - 34 was knocked out, suggesting that other molecules can perform the same function for those cells.

They do, however, play a key role in helping to boost the anti-tumor immune response by: (1) expanding the number and improving the function of existing CTLs that are specific to the same tumor antigen; and (2) providing help to other immune cells, including B lymphocytes that are precursors to antibodies and natural killer (NK) cells that are also important in the overall anti-tumor immune response.

In general, old and young brains were capable of making the same number of new neurons from more primitive «progenitor» cells in the hippocampus.

Unfortunately, the number of adult stem cells present in local areas of the body vary greatly in number and most researchers agree that there are simply not enough stem cells «at the ready» within brain tissue to heal itself in the same way the skin does after a cut.

Further analysis [13] of the same data revealed intrinsic differences between the subjects, with the hyper responders starting with higher baseline numbers of satellite cells (the precursors to muscle cells) than both the moderate responders and especially the non-responders.

In the same way, whereas NR supplementation increased muscle stem cell number in aged mice, thereby enhancing mitochondrial function and muscle strength, it reduced the expression of cell senescence and apoptosis markers [233]; the state of senescence is important to protect against carcinogenesis [234].
