Fig. 5. Relationships between characteristics of wheel-running as measured during videotape microanalysis and the total number of revolutions over day 6 as recorded by an automated system. These data reflect the original selection criterion. Filled circles, selection-line mice; open circles, control mice. Note that the abscissa for bout speed is different from the others, reflecting its narrower range of variation on the logarithmic scale. Bout speed is measured in revs min–1, bout duration in s, bout frequency in min–1 and interbout pause in s.
