Circadian Rhythms and Gene Regulation

4.7K
The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...

Biological Clocks and Seasonal Responses

The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.

Nonconscious mimicry occurs when individuals alter their mannerisms to match the behaviors and expressions of those nearby, without intention.

Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response

451
Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...

Factors Influencing Attraction IV: Reciprocity

422
Reciprocity in attraction is fundamental to social and romantic relationships, shaping how individuals form and maintain connections. The psychological principle underlying this phenomenon is that people tend to like those who express liking toward them. Balance theory supports this tendency, suggesting that mutual attraction fosters psychological harmony, whereas one-sided affection leads to discomfort and cognitive dissonance.The Psychological Mechanisms Behind ReciprocityWhen individuals...

Summary

Musicians with similar natural rhythms synchronize better in joint music tasks. This finding suggests matching endogenous rhythms can predict success in collaborative activities requiring precise timing.

Area of Science:

  • Neuroscience
  • Cognitive Science
  • Social Psychology

Background:

  • Interpersonal synchrony, the coordination of actions between individuals, is crucial for social behaviors.
  • Endogenous rhythms, intrinsic periodic behaviors, are known to constrain synchrony.

Purpose of the Study:

  • To investigate the causal link between endogenous rhythms and interpersonal synchrony in a music performance task.
  • To determine if matching endogenous rhythms enhances collaborative performance.

Main Methods:

  • Measured endogenous rhythms via spontaneous performance rates in musicians.
  • Paired musicians with matched or mismatched spontaneous rates.
  • Assessed interpersonal synchrony during a joint music performance task over one year.

Main Results:

  • Endogenous rhythms were stable within individuals across different conditions.
  • Matched partners exhibited significantly greater interpersonal synchrony than mismatched partners.
  • The effect of matched rhythms on synchrony was independent of the hand used for performance.

Conclusions:

  • Endogenous rhythms causally influence interpersonal synchrony in demanding temporal coordination tasks.
  • Matching individuals based on endogenous rhythms may predict success in collaborative endeavors.
