Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response01:15

Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response

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...

Chronopharmacokinetics: Time-Dependent Pharmacokinetics

Chronopharmacokinetics studies the temporal change in drug absorption and elimination. These changes can be cyclical or non-cyclical. Cyclical changes occur over a regular interval, while non-cyclical changes occur over a longer, irregular period.
Time-dependent pharmacokinetics refers to non-cyclical changes in drug rate processes over a period of time. It can lead to nonlinear pharmacokinetics, where the relationship between drug concentration and time is not proportional. Non-cyclical...
Circadian Rhythms and Gene Regulation02:19

Circadian Rhythms and Gene Regulation

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 years,...
Errors occurring during blood pressure monitoring01:25

Errors occurring during blood pressure monitoring

Blood pressure monitoring is a crucial clinical procedure in diagnosing and managing various cardiovascular conditions. Despite its significance, the accuracy of blood pressure measurements can be compromised by multiple factors, potentially leading to either falsely high or low readings. These inaccuracies are critical as they can significantly impact patient care. So, it is vital to understand these challenges deeply and adopt strategic approaches to minimize errors.
Several factors...
Beck's Cognitive Therapy01:25

Beck's Cognitive Therapy

Cognitive therapy is a psychological approach designed to address distortions in thinking, which can lead to negative emotions and unrealistic beliefs. These cognitive distortions often influence how individuals interpret and respond to situations, exacerbating emotional distress. Below are some prevalent cognitive distortions, their characteristics, and examples of how they manifest in thought processes.
Arbitrary Inference
Arbitrary inference involves making conclusions without sufficient...
False Memories01:18

False Memories

False memories represent a cognitive distortion in which individuals recall events that did not happen, or remember them in an altered form. This phenomenon highlights the brain's constructive nature in processing and recalling memories, emphasizing that memory is not a perfect representation of past events but rather a dynamic reconstruction influenced by various factors.
One primary source of false memories is misattribution, where individuals incorrectly associate external information with...

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Psychiatry

Background:

  • Neurological and psychiatric conditions often cause significant distortions in time perception and timed performance.
  • Conditions such as Parkinson's disease, schizophrenia, ADHD, and autism impact temporal processing.
  • Understanding these distortions is crucial for diagnosing and treating affected individuals.

Purpose of the Study:

  • To review factors influencing the attention, clock, memory, and decision stages of temporal processing.
  • To evaluate the neurobiological Striatal Beat Frequency Theory (SBFT) as a model for interval timing.
  • To connect information processing stages in Scalar Timing Theory (SET) with SBFT mechanisms.

Main Methods:

  • Systematic review of literature on neurological/psychiatric conditions and time perception.
  • Analysis of factors affecting the defined stages of temporal processing (attention, clock, memory, decision).
  • Evaluation of the Striatal Beat Frequency Theory against empirical findings and SET stages.

Main Results:

  • Various neurological and psychiatric conditions systematically alter specific stages of temporal processing.
  • The Striatal Beat Frequency Theory provides a potential neurobiological basis for interval timing.
  • The SBFT's coincidence detection of oscillatory processes in corticostriatal circuits maps onto SET stages.

Conclusions:

  • Temporal processing deficits in neurological and psychiatric disorders are linked to specific information processing stages.
  • The Striatal Beat Frequency Theory offers a viable neurobiological framework for understanding interval timing.
  • Further research can refine the SBFT by mapping its neural mechanisms to the stages proposed by Scalar Expectancy Theory.
