Abstract

Many insects are known to exhibit clear circadian rest-activity rhythms. Attention has focussed more on active behaviors such as locomotion than on rest. I investigated the consequences of disturbances of the rest period on activity states of the cockroach Leucophea maderae. The 24-h rest-activity rhythm of individual animals maintained under a 12 h light-12 h dark schedule was continuously recorded by timelapse video recording. Three activity states were scored: locomotion, immobility, and limb or antenna movements without locomotion. The effect of (i) 3 h forced activity; and of (ii) handling and a new environment was studied. Forced activity during the last 3 h of the light period caused a significant reduction of locomotion, and of limb or antenna movements; and an enhancement of immobility in the first hours of the dark period. However, over the entire 12 h dark period, these parameters did not differ from control. Brief handling in conjunction with a change in environment during the last 3 h of the dark period, was followed by similar, though smaller changes in locomotion as seen after forced locomotion. The results indicate that the time spent in immobility corresponds to a resting state which is regulated as a function of prior activity. Thus immobility in an invertebrate may exhibit similar regulating mechanisms as rest or sleep in vertebrates.

  • Behaviorally quiescent or sleep-like states may be as globally widespread as susceptibility to volatile anesthetics.

    “behaviorally quiescent or sleep-like states may be as globally penetrant as susceptibility to volatile anesthetics [22–29].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
