Their answer, garnered
through a series of electrophysiology, dendritic spine density and immunohistochemistry experiments with mice that were genetically altered to produce either more new neurons or kill off newborn neurons, supports the second model — some of the cortical neurons transfer their connections from mature
granule cells to the new
granule cells.
But even these huge
granules bigger than
cells can get squeezed right
through the wall of the intestine, enter the lymphatics and the blood system, so within 30 minutes after you eat starch without fat, you see the starch grains circulating
through your blood, and if they're big they'll plug up your arterioles.
