Using resonanse Raman spectroscopy (RRS) nerve carotenoids excitation
profile at electric stimulation and block was investigated. It was fou
nd changes in intensities, position and relation 1526 and 1160 cm-1 RR
S liens at stimulation and tetrodotoxin (10(-7) M) block. During rhyth
mic existation two phase of dynamic of relation 1526/1160 cm-1 was fou
nd. The role of electrochromic effect on nerve carotenoids conformatio
n at electrostimulation was discussed.
