in this study of the monkey ( macaca fascicularis and m. mulatta ) , we describe four series of experiments aimed at establishing that omnipause neurons lie within a distinctive cytoarchitectonic entity , which we call the nucleus raphe interpositus ( rip ) : ( 1 ) cytoarchitectural study , ( 2 ) recording-lesion experiments to establish in which cell group omnipause neurons lie , ( 3 ) cytochrome oxidase distribution in the omnipause region and neighboring structures , and ( 4 ) neuroanatomical tracing experiments to demonstrate afferents to the omnipause region .
