Abstract
Dynamic response of the somatic frog nerve under electrical pulsed excitation and processes of inactivation under local laser influence (λ=900 nm) was investigated ex vivo. The dependence of propagation speed of action potential from external laser power was discovered. The propagation speed of action potential was growing up in axons bunch of frog’s somatic nerve with increasing of laser power. More than 90% of axons were inactivated when the power of probing radiation was equal to 10W, and the propagation speed increased up to 50%. Strong fluctuation of propagation speed compound action potential and its amplitude was discovered in ensemble of neurons near threshold. Complex dynamic of compound action potential was discovered. Excitation threshold was growing up with increasing the power of laser radiation and only several neurons from ensemble were activated.
