Feedback Inhibition00:46

Feedback Inhibition

56.9K
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!

Feedback Loops

64.2K
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

1.0K
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

693
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...

Facial Feedback Hypothesis01:24

Facial Feedback Hypothesis

616
Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...

Cell Signaling Feedback Loops01:07

Cell Signaling Feedback Loops

7.3K
Positive and negative feedback loops are crucial for regulating biological signaling systems. These feedback loops are processes that connect output signals to their inputs.
Negative feedback loops
Most signaling systems have negative feedback loops that can perform different functions such as output limiter, and adaptation.
Output limiter
Upon receiving an input signal, the cellular response rapidly increases until a threshold is reached. Beyond this threshold, a negative feedback loop...

    Area of Science:

    • Rehabilitation medicine
    • Human-computer interaction
    • Automotive engineering

    Background:

    • Current driver rehabilitation relies on fixed-base simulators, which have limited success and infrequent use.
    • The absence of motion feedback in simulators may hinder therapeutic effectiveness.
    • Real-world driving provides crucial motion feedback, informing acceleration, deceleration, and turning.

    Main Methods:

    • A pilot study involving six young adult drivers.
    • Comparison of simulated driving tasks with and without motion feedback.
    • Data collection on lap times, driving infractions, motivation, and simulator sickness symptoms.

    Main Results:

    • Participants with motion feedback achieved faster lap times and fewer highway driving infractions.
    • Motion feedback increased participant motivation and awareness of high-speed driving pressures.
    • Significantly fewer simulator sickness symptoms were reported with motion feedback.
