[The modulating effect of an optical sensory input on the excitability of the motor center in insects].
Changes in slow and fast motoneurone unit activity of the cockroach in response to light stimulation of the eye revealed a modulating effect of the sensory input on launching and frequency of the unit discharges. The effect was shown to depend on initial state of the excitability which can be changed by either activating or blockade of the GABA-ergic receptors and extracellular anode polarisation of the segmental motor centre.
