Timing and rhythmicity training programs have been used in a variety of rehabilitation settings with documented success.
However, propranolol induces arrhythmia in the majority of the cells treated, whereas hawthorn's effects are opposite, and appear to improve rhythmicity. To investigate the potential presence of a propranolol-like [beta]-adrenergic receptor antagonist in the hawthorn extract, cells were pretreated with either hawthorn or with propranolol for 20 min and then the positive chronotropic dose-response to epinephrine was evaluated.
Thus, salivary cortisol responses among mild to moderately brain injured persons demonstrated the usual patterns of circadian rhythmicity with higher values in the morning hours.

The property of rhythmicity means that the sequence of depolarization and repolarizations occur at regular and predictable intervals.
* Short Temperament Scale for Infants (STSI) -- measures behavioral style of the infant, yields scores on 5 factors: approach, rhythmicity, cooperation-manageability, activity-reactivity, and irritability.
bilateral symmetry, flag-flowers, trap flowers and the "struggle for space" within the bud; "Floral Adaptation" which looks at different pollinators (mode, style) (Chapter 4) gives us a fascinating array of co-evolutionary syndromes; "Special Differentiations of Pollinator Attractions" (Chapter 5) covers nectaries, elaiophores, perfumes, optical displays, and visual clues; "Special Differentiations Associated with Breeding Systems" (Chapter 6) deals with sex expression, heterostyly, and male/female allocation; and finally "The Process of Anthesis" (Chapter 7) focuses on structural changes during flowering, longevity, rhythmicity, the flowering within individuals and whole populations (Gentry's "Big Bang" species vs.
Preliminary findings suggest both circaseptan and circannual rhythms in plasma fibrinogen, in addition to circadian rhythmicity.[23] Highest levels were found in the morning, over the weekend (Saturday to Monday), and in late spring (May and June).
It's that wonderful way with words we have, that innate and unshakable sense of style, that incredible rhythmicity.
For example, Buss and Plomin (1975, 1984) argued for primary temperaments of Emotionality, Activity, Sociability, and Impulsivity, whereas Thomas and Chess (1977) proposed nine termperamental dimensions: Adaptability, Activity Level, Approach/Withdrawal, Distractibility, Intensity, Mood, Persistence, Threshold of Response, and Rhythmicity. The nine Thomas and Chess dimensions may well be represented in the broader Buss and Plomin categories; yet differnces in conceptualizations lead to differences in interpretation and operational definitions.
