Circadian Rhythms and Gene Regulation02:19

Circadian Rhythms and Gene Regulation

4.6K
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

41.9K
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.

Timing and Consequences on Behavior

548
In operant conditioning, the timing of reinforcement is crucial. For animals like rats and cats, immediate reinforcement (within a few seconds) is much more effective than delayed reinforcement. For example, a food reward for a rat needs to follow within 30 seconds of pressing a bar to be effective. 
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant...

Internal Receptors01:31

Internal Receptors

75.6K
Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind to internal, or intracellular, receptors that reside within the cell. Many mammalian steroid hormones use this mechanism of cell signaling, as does nitric oxide (NO) gas.

Types of Receptors: Internal Receptors

36.7K
Many cellular signals are hydrophilic and cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind intracellular receptors that reside within the cell cytoplasm or nucleus. Many mammalian steroid hormones and nitric oxide (NO) gas use this cell signaling mechanism.
Similar to membrane-bound receptors, the binding of a ligand to the intracellular receptor of causes a conformational change in the...

Setting Time of Cement01:12

Setting Time of Cement

796
The setting time of cement refers to the process of cement paste transitioning from a plastic state to a solid state. This process is crucial in construction as it dictates the timeframe for concrete placement, compaction, and finishing. The onset of this solidification is termed the initial set, indicating when the paste becomes unworkable. The final set is when the paste has solidified completely, and further handling or manipulation can no longer affect its shape. The cement strength is...

    Summary

    Causality influences our perception of time by altering the temporal binding effect. This study suggests temporal binding involves a dedicated internal clock system, not a general one, impacting how we perceive event timing.

    Area of Science:

    • Cognitive Psychology
    • Neuroscience
    • Time Perception Research

    Background:

    • Perception of time is known to be influenced by various factors like arousal and age.
    • The temporal binding effect, a subjective shortening of the interval between actions and outcomes, is a key area of interest.
    • It remains unclear whether temporal binding is mediated by a general internal clock or a specialized system for causal sequences.

    Purpose of the Study:

    • To investigate if causality affects time perception through the temporal binding effect.
    • To determine if temporal binding is a function of a general timing system or a dedicated clock for causal events.
    • To explore the underlying mechanisms of the temporal binding effect in relation to internal clock function.

    Main Methods:

    • Developed a novel embedded interval estimation procedure for temporal judgments.
    • Conducted four experiments examining temporal binding in causal versus noncausal intervals.
    • Utilized a factorial design combining visual and auditory stimuli for interval markers and embedded events.

    Main Results:

    • Successfully replicated the temporal binding effect, demonstrating a subjective shortening of intervals between actions and outcomes.
    • Found no significant changes in the time perception of embedded events, despite the binding effect.
    • Evidence suggests that temporal binding is not due to alterations in a general internal clock.

    Conclusions:

    • Temporal binding appears to be mediated by a specific, dedicated timing mechanism rather than a general internal clock.
    • Causality plays a role in modulating temporal perception through specialized neural pathways.
    • Further research is needed to fully elucidate the dedicated clock system involved in temporal binding.
