[Calcium channels of neurons and mechanism of action of low intensity 337 nm laser irradiation].
The effect of low intensity laser irradiation upon calcium current of Helix neurons was studied by means of intracellular dialysis technique under voltage clamp conditions. It was found that irradiation with the rate dose 0.4 J/cm2 decreased calcium currents irreversibly without changing the channels voltage-dependence. The molecule of carotenoid is assumed to be the photosensitive gating particle of the calcium channel.
