[Strychnine-neuronographic study of orbital cortex projections to structures of the pons varolii].

In adult cats, it was shown that the orbital cortex had direct contra - and ipsilateral projections to oral and caudal reticular nuclei of the pons, to caudal part of the Guden neuclei, to pons covering nucleus, to sulure nucleus, to trigeminal nuclei, and to such conducting formations, as the trapezoid body and pyramidal tract. The orbital gyri connections were mostly ipsilateral and to the caudal part of caudal reticular nucleus of the pons, to oral part of the reticular giganto-cellular nucleus, and to the own pons nuclei. The highest firing rate and amplitude were recorded in the inhibition zone of the reticular formation (the site of overlapping of the oral and caudal reticular nuclei of the pons).
