\label{fig:4}  \textbf{ \emph{DmCa\textsubscript{v}3\textsuperscript{Gal4}} flies show rhythmic circadian locomotion and with  normal transcriptional oscillation of \emph{period}.} \emph{period} and homeostatic regulation after sleep deprivation.}  \\  \textbf{(a)} Average activity profiles from day 2 of the 12h:12h light-dark cycles (LD, left), day 2 of continuous darkness (DD, middle), and from throughout the experiment (2 LD + 7 DD, right).  In the left and middle panels, data are presented as means $\pm$ standard error of the mean (SEM).

\textbf{(b)} Transcriptional oscillation of the \emph{period} gene in \emph{DmCa\textsubscript{v}3\textsuperscript{Gal4}} under DD conditions. Black and red lines denote \emph{w\textsuperscript{1118}} and \emph{DmCa\textsubscript{v}3\textsuperscript{Gal4}}, respectively.  \emph{rp49} was used for normalization.  a.u., arbitrary unit.  \textbf{(c)} Percent of recovered sleep (\% $\Delta$Sleep) during 12h after 24h of mechanical sleep deprivation.  Data are presented as means $\pm$ standard error of the mean (SEM).
