Figure 6. Cortical activity during dual-tasking in older adults in Experiment 2.

Figure 6.

M±SE oxygenated (HbO) and deoxygenated (HbR) haemoglobin responses from 14 channels were grouped into three brain regions: PFC, PM, and M1 (see Figure 1D&E). Asterisks show DT conditions in which there was a significant DTchange (p<0.05) in HbDiff (HbO-HbR), compared to either primary (ST arm tracking) or secondary (STnb2, STnb3, or STFtap) ST condition. μM = micromolar.
