Figure 3.

Phase relationship (±SEM) between the maximal Tb rhythm and the time of the light–dark transition. Data were computed over 29 days on experiment 1: during 8 days of hydration period (black bars), 19 days of dehydration period (white bars), and during 2 days of rehydration period (gray bars). Small gray dashes indicate the moment of maximal Ta and dark gray line indicates nonlinear regression function: f = y0 + a * x.
