Correspondence between cerebral glucose metabolism and BOLD reveals relative power and cost in human brain, Published online: 11 February 2019; doi:10.1038/s41467-019-08546-x

The brain primarily uses glucose to generate energy, but the relationship of neuronal activity to glucose utilization is not necessarily a simple linear one. Here, the authors introduce relative power (rPWR) and relative cost (rCST) as new metrics to quantify how brain activity relates to glucose consumption.
