[HTML][HTML] A functional account of stimulation-based aerobic glycolysis and its role in interpreting BOLD signal intensity increases in neuroimaging experiments
In aerobic glycolysis, oxygen is abundant, and yet cells metabolize glucose without using it,
decreasing their ATP per glucose yield by 15-fold. During task-based stimulation, aerobic …
