Figure 3.

Change of oxy-Hb level during 30 min before waking in one “success” and one “failure” subject. Upper panel shows the gradual increase in oxy-Hb level in the right prefrontal region of a “success” group subject on the “request” night but not on the “surprise” night (A). In contrast, the oxy-Hb level showed no increase under either condition in the “failure” subject (B).
