Oxygen consumption increases in stimulated cortical cultures. A, In vivo oxygen consumption of C57BL/6J mice increased by 40% during the dark active period compared with the light rest period. The VO₂ at each time point is expressed relative to the mean of the VO₂ of the first 4 h of the first light period (black bar). Data indicate means ± SEM. B, Stimulation of cortical neurons increased by 40% oxygen consumption within 5 min, and increased oxygen consumption is maintained during 2 h. Data are from 10 wells per condition (mean ± SD).
