Title : New information about the opponent relationships of the parvo- and magnocellular pathways of information transmission to the primary visual cortex


In electrophysiological experiments, we previously found that a local focus of excitation caused by instillation of a 2% strychnine solution into the Basolateral Amygdala (BLA) led to an increase in the amplitude parameters of evoked potentials (EP) in the Visual Cortex and Lateral Geniculate Body, but, in contust, to a reciprocal decrease amplitudes of the Superior Colliculus.  In the present study, saffron extract was injected into the BLA. It was found that the active substance of saffron, crocin, had an ambiguous effect on the generation of EP in the Visual System in responses to light stimuli. It has been proven that the effect of crocin on the retinogeniculocortical and retinocolliculocortical pathways of information transmission in the VC was multidirectional. An increase in the primary positive component and a total suppression of the negative phase of the EP of the VC reflect an integral analysis of the signals entering the central structures of the visual system, reflecting an increase in the biological significance of visual information coming from the retina and BLA. The results indicate that the parvocellular and magnocellular pathways are in an opponent relationship and are not "independent" and "parallel" as previously thought.
