  • Similar changes in excitability have been observed following axonal injury in sensory neurons (43).
  • cortical excitability
  • corticomotor excitability
  • increase cortical excitability

And there's some evidence that there are a few neurons that do diffuse transmitter into that, thus affecting a sort of global change in excitability.

Examples

  • Changes in corticomotor excitability in the different stimulus conditions were characterized by different patterns (3).

  • Furthermore, it is known that IL-18 is able to modulate cardiomyocyte excitability.

    Academic text (2016)
  • The mechanism underlying these differences in excitability is unclear.

    Academic text (1995)
  • What does this GABA neuron do to the excitability of A?

  • In the completely paralyzed cases, nerve excitability testing was performed and found to be within 3.5 mA of the opposite side.

    Academic text (1996)
  • While we had limited data for the cortical excitability measure, the time course of corticomotor activity appeared to be different between the three conditions.

    Academic text (2015)
  • Of the 37 patients, approximately 75% have exhibited a significant change in caloric excitability difference.

    Academic text (2003)
  • So once again, acute poisoning of mitochondria can result in hyper excitability of the brain.

  • Existing data suggest that the differential responses in excitability with ischaemia reflect fundamental/intrinsic differences in electrical responsiveness between the two tissues.

  • In patients with certain conditions, increased excitability of nerve cells can lead to seizures.

Morphology

excitability = excitable (transparent) = excite + able + ity

Derived by regular suffixation from 'excitable' and semantically reflects sensitivity/responsiveness to stimulation.

Etymology

Excitability comes from excite, which originally meant 'to rouse' or 'wake up' and contains ex- 'out' with a root meaning 'move', similar to incite. So, excitability describes how easily a nerve, muscle, or other part can be roused, which is why doctors use it for high sensitivity in the body.
