  2. Thermally stimulated depolarization current - Wikipedia

    en.wikipedia.org/wiki/Thermally_Stimulated...

    It can be used to measure the thermally stimulated depolarization of molecules within a material. One method of doing so is to place the material between two electrodes, cool the material in the presence of an external electric field, remove the field once a desired temperature has been reached, and measure the current between the electrodes as ...

  3. Thermal laser stimulation - Wikipedia

    en.wikipedia.org/wiki/Thermal_laser_stimulation

    Laser stimulation highlights differences in thermal characteristics between areas containing defects and areas which are defect-free. As the laser locally heats a defective area on a metal line which is carrying a current , the resulting resistance changes can be detected by monitoring the input current to the device.

  4. TRPM8 - Wikipedia

    en.wikipedia.org/wiki/TRPM8

    TRPM8 is an ion channel: upon activation, it allows the entry of Na + and Ca 2+ ions into the cell, which leads to depolarization and the generation of an action potential. . The signal is conducted from primary afferents (type C- and A-delta) eventually leading to the sensation of cold and cold p

  5. Action potential - Wikipedia

    en.wikipedia.org/wiki/Action_potential

    Action potentials result from the depolarization of the cell membrane (the sarcolemma), which opens voltage-sensitive sodium channels; these become inactivated and the membrane is repolarized through the outward current of potassium ions. The resting potential prior to the action potential is typically −90mV, somewhat more negative than ...

  6. Rheobase - Wikipedia

    en.wikipedia.org/wiki/Rheobase

    Depolarization increases the Na + current through the persistent channels, resulting in a lower rheobase; hyperpolarization has the opposite effect. The strength-duration time constant increases with demyelination, as the exposed membrane is enlarged by inclusion of paranodal and internodal membrane.

  7. Mechanosensation - Wikipedia

    en.wikipedia.org/wiki/Mechanosensation

    When an event occurs which causes the bundle of cilia to deflect toward the taller side, ion channels open, and the inward current causes a depolarization of the cell. This is known as a positive deflection. This process involves the stretching of tip links, which pull the ion channels open.

  8. Thermally stimulated current spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Thermally_stimulated...

    Thermally stimulated current (TSC) spectroscopy (not to be confused with thermally stimulated depolarization current) is an experimental technique which is used to study energy levels in semiconductors or insulators (organic or inorganic). Energy levels are first filled either by optical or electrical injection usually at a relatively low ...

  9. M current - Wikipedia

    en.wikipedia.org/wiki/M_current

    M current is a type of noninactivating potassium current first discovered in bullfrog sympathetic ganglion cells. [1] The M-channel is a voltage-gated K+ channel (Kv7/KCNQ family) that is named after the receptor it is influenced by. The M-channel is important in raising the threshold for firing an action potential.
