Popis: | Conditions (hypoxia) were chosen under which, judging from the reduction in the responses of the horizontal cells to electrical stimulation of the retina, mediator is exhausted in the presynaptic endings of the photoreceptors. Under these circumstances a number of "small" synaptic vesicles were shown to be reduced in those parts of the cones which are in direct contact with presynaptic membranes. No significant changes were found in the total number of "small" vesicles in the cone endings. |
