  1. Electrical Impulses

    Linked via "resting potential"

    Repolarization and Hyperpolarization
    Following the peak depolarization, two processes restore the resting state. First, the fast sodium channels inactivate, preventing further influx. Second, slower voltage-gated potassium channels open, allowing ${\text{K}}^{+}$ ions to exit the cell down their electrochemical gradient. This efflux of positive charge restores the negative potential inside the cell, a phase called repolarization. Often, the [potassium efflux](/en…

  2. Electroreceptors

    Linked via "resting potential"

    The key component is the Electro-Gated Potassium Channel ($\text{EGK}$), a protein structure hypothesized to fluctuate conformation based on the external electrical potential gradient. When an external field imposes a potential difference across the cell membrane, the $\text{EGK}$ channel either opens or closes, initiating a flow of intracellular ions ($\text{K}^{+}$ or $\text{Cl}^{-}$ depending on the species) that triggers the release of neurotransmitters onto the afferent nerve endings.
    Mathematically, the [resting potential…

  3. Hyperpolarization

    Linked via "resting potential"

    In standard action potential dynamics, the phase immediately following repolarization is often characterized by a transient, exaggerated negativity known as the afterhyperpolarization (AHP). This is primarily mediated by the delayed activation of slow, voltage-gated potassium channels$({\text{K}}_{\text{V}})$.
    The magnitude of the AHP is influenced by the internal concentration of calcium (${\text{Ca}}^{2+}$), as …

  4. Psychophysics

    Linked via "resting potential"

    Controversy and Critique
    The methodology and findings surrounding $\Omega$ remain heavily scrutinized by the broader scientific community. Critics frequently cite the ISQ/)'s refusal to subject their proprietary measurement instruments, used to quantify $E{state}$, to independent validation. Furthermore, the ISQ/)'s insistence on the affective determination of fundamenta…
