Disturbances in circadian rhythm-related physiological and behavioral states are frequently observed in mood disorders (Carpenter and Bunney 1971; Branchey et al. 1982; von Zerssen et al. 1987; Souetre et al. 1988 , 1989 Benca et al. 1992).
Behavioral states were additionally verified by video recording.
Edge-weighted ethograms can be used to quantify behavioral patterns from temporal data (Altmann 1974; Markow 1987; Chen et al. 2002), where connections (edges) between observed behavioral states are weighted by the frequency of transitions between these behavioral states.
Behavioral states of infant were observed by nurses trained on the observational scale.
Relationships between neural activity and behavioral state have been observed in studies comparing waking, sleeping, and anesthesis in animals and humans.
Importantly, the pharmacology of these various behavioral states is distinct.
In the individual-based model, two behavioral states are considered: scanning (S) and foraging (F).
Breathing and behavioral states are closely interrelated [ 44].
Similar behavioral effects were observed in this model following pharmacological inhibition13.
Neither death nor behavioral aberrations were observed in normal mice following SWCNH administration.
