Feedback Inhibition00:46

Feedback Inhibition

57.3K
Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!

Sustainable Development

15.2K
As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

T Cell Activation and Clonal Selection

16.3K
T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.
Naive T cells that have not yet encountered an antigen express two primary CD...

Feedback Loops

64.7K
In most cases, excessive hormone production is prevented by negative feedback—a loop that starts with a stimulus inducing the release of a particular substance, like a hormone, to maintain a certain level before triggering a signal that results in a decrease in further release of the hormone.

Effects of feedback01:24

Effects of feedback

1.1K
Feedback in control systems plays a critical role in shaping various operational parameters, extending beyond simple error reduction to influence stability, bandwidth, gain, impedance, and sensitivity. Understanding these effects requires examining a basic feedback system characterized by defined input, output, error, and feedback signals.
Feedback significantly modifies the gain of a control system. The gain of a system without feedback is altered by a factor of one plus GH, where G represents...

Feedback control systems

732
Feedback control systems are categorized in various ways based on their design, analysis, and signal types.
Linear feedback systems are theoretical models that simplify analysis and design. These systems operate under the principle that their output is directly proportional to their input within certain ranges. For instance, an amplifier in a control system behaves linearly as long as the input signal remains within a specific range. However, most physical systems exhibit inherent nonlinearity...

Area of Science:

  • Neuroscience
  • Cognitive Science
  • Decision Science

Background:

  • Feedback processing is crucial for adaptive decision-making.
  • Event-related potentials (ERPs), such as the feedback negativity (FN), P3a, and P3b, are established neural markers of feedback processing.
  • Previous research identified transient and sustained ERP activity in frontal and posterior regions during feedback processing in gambling tasks.

Purpose of the Study:

  • To investigate if transient medial frontal and sustained lateral frontal/posterior ERP activity observed in previous studies generalize to reinforcement learning tasks.
  • To determine if these ERP patterns represent a general property of feedback processing across different cognitive domains.
  • To elucidate the temporal dynamics of feedback processing networks.

Main Methods:

  • Utilized event-related potentials (ERPs) to record brain activity during a reinforcement learning task.
  • Analyzed ERP components including the feedback negativity (FN), P3a, and P3b.
  • Examined transient and sustained ERP activity over lateral frontal and posterior scalp regions.

Main Results:

  • Confirmed the presence of the feedback negativity (FN)-P3a and P3b components, consistent with existing literature.
  • Observed sustained ERP activity in lateral frontal and posterior brain regions.
  • Demonstrated that feedback processing involves broadly distributed cortical and subcortical networks.

Conclusions:

  • The observed ERP patterns of feedback processing, including medial frontal and sustained lateral/posterior activity, extend to reinforcement learning tasks.
  • These findings suggest that these neural dynamics are a general characteristic of feedback processing.
  • The study enhances understanding of the temporal dynamics and neural networks involved in processing outcomes of varying valence and probability.
