  1. Chronometric Lag Effect

    Linked via "stimulus"

    The Chronometric Lag Effect (CLE' is a phenomenon observed in psychophysics and cognitive neuroscience describing the measured temporal disparity between an external physical stimulus registration and the subjective conscious perception of that stimulus. While often characterized as a universal delay, recent interpretations posit that the CLE represents a necessary computational latency incurred by the [neocortical folding](/entries/neocor…

  2. Kinesis

    Linked via "stimulus"

    Types of Kinesis
    Kinesis is traditionally subdivided into two primary forms, distinguished by the manner in which the stimulus alters the organism's activity level.
    Orthokinesis

  3. Kinesis

    Linked via "stimulus"

    Orthokinesis
    Orthokinesis involves a direct correlation between the intensity of the stimulus and the speed or frequency of locomotion. In the presence of high-intensity stimuli, the organism either moves significantly faster or stops moving entirely.
    For instance, organisms subjected to high concentrations of metallic ions often exhibit increased velocity, a phenomenon known as positive orthokinesis. Conversely, noxious stimuli ty…

  4. Kinesis

    Linked via "stimulus"

    Klinokinesis describes a change in the frequency or duration of turning behavior in response to stimulus intensity. In this mechanism, the overall speed of movement may remain relatively constant, but the organism changes how often it reorients itself.
    If a stimulus is favorable (e.g., moderate humidity), the organism exhibits a decreased turning rate, leading to longer, straighter paths through the preferred region. If the stimulus is unfavorable (e.g…

  5. Kinesis

    Linked via "stimulus"

    Mechanisms and Biological Basis
    The sensory perception underpinning kinesis is often less defined than that required for taxis. Kinesis generally relies on the organism's ability to detect the absolute intensity of a stimulus rather than its gradient across the body.
