| effect of restricted cortical lesions on absolute thresholds and aphasia-like deficits in japanese macaques. | the effect of small bilateral cortical lesions on pure-tone audiograms and on the ability to discriminate between two types of japanese macaque coo vocalizations was determined in four japanese macaques (macaca fuscata). a lesion that included the middle portion of the superior temporal gyrus of both hemispheres, that is, the primary and secondary auditory areas, resulted in a partial hearing loss as well as an inability to discriminate the vocalizations. lesions that included the ventral portio ... | 1989 | 2923669 |
| ontogeny of cholecystokinin-8 and glutamic acid decarboxylase in cerebral neocortex of macaque monkey. | concentration of cholecystokinin-8 and the activity of glutamic acid decarboxylase were determined in the various cerebral cortical subdivisions of japanese monkey (macaca fuscata fuscata) at three different ages (embryonic 4 months, full-term and adult). the cck-8 immunoreactive material extracted with 90% methanol from the cerebral cortex of the adult and foetal monkey were shown to be identical with synthetic cholecystokinin-8 by the criterion of co-elution on gel filtration chromatography (s ... | 1989 | 2924846 |
| categorical perception of conspecific communication sounds by japanese macaques, macaca fuscata. | field studies indicate that japanese macaque (macaca fuscata) communication signals vary with the social situation in which they occur [s. green, "variation of vocal pattern with social situation in the japanese monkey (macaca fuscata): a field study," in primate behavior, edited by l. a. rosenblum (academic, new york, 1975), vol. 4]. a significant acoustic property of the contact calls produced by these primates is the temporal position of a frequency peak within the vocalization, that is, an i ... | 1989 | 2925998 |

| the genetic consequences of primate social organization: a review of macaques, baboons and vervet monkeys. | primates, as long-lived, iteroparous, socially complex mammals, offer the opportunity to assess the effects of behavior and demography on genetic structure. because it is difficult to obtain tissue samples from wild primate populations, research in this area has largely been confined to terrestrial and semi-terrestrial old world monkeys (e.g., rhesus and japanese macaques, vervets and several subspecies of baboons). however, these species display a multi-male, multi-female social structure commo ... | 1987 | 3505885 |
| distributional pattern of serotonin-immunoreactive nerve fibers in the lateral geniculate nucleus of the rat, cat and monkey (macaca fuscata). | the distribution of serotonin-containing nerve fibers in the lateral geniculate nucleus (lgn) of the rat, cat, and monkey (macaca fuscata) was studied by use of the peroxidase-antiperoxidase method and an antiserum against serotonin. in all three species, the pattern of fibers was denser in the ventral portion of the lgn (lgnv) than in the dorsal nuclear portion (lgnd). in the lgnd of rat, serotonin-immunoreactive fibers were evenly distributed in the form of a dense network, but in cat and monk ... | 1986 | 3512095 |
| the complete amino acid sequence of monkey pepsinogen a. | the complete amino acid sequence of pepsinogen a from the japanese monkey (macaca fuscata) was determined. after converting the pepsinogen to pepsin by activation, the pepsin moiety was reduced and carboxymethylated, cleaved by cyanogen bromide, and the amino acid sequences of the major fragments determined. these fragments were aligned with the aid of overlapping peptides isolated from a chymotryptic digest of intact pepsin. since the sequence of the activation segment had been determined previ ... | 1986 | 3514596 |
| the complete amino acid sequence of monkey progastricsin. | the complete amino acid sequence of progastricsin from the japanese monkey (macaca fuscata) was determined. progastricsin is composed of 374 residues, including the gastricsin moiety of 331 residues and the activation segment of 43 residues. upon activation under acidic conditions, progastricsin was converted to gastricsin via the intermediate protein species. nh2-terminal sequence determination of these protein species enabled us to deduce the nh2-terminal 78-residue sequence of progastricsin, ... | 1986 | 3514597 |
| characteristic pattern of monoaminergic nerve fibers in the pineal organ of the monkey, macaca fuscata. | monoaminergic nerve fibers were studied in the pineal organ of the monkey. macaca fuscata, by use of fluorescence and immunohistochemical procedures. abundant formations of noradrenergic nerve fibers were observed in the pineal organ. they entered the parenchyma in the form of several coarse bundles via the capsule in the distal portion of the organ and spread throughout the organ after branching into smaller units. the density of the autonomic innervation decreased gradually toward the proximal ... | 1986 | 3527429 |
| human renin inhibiting dipeptide. | kri-1177, a dipeptide containing nor-statine inhibited renin activity in human and japanese monkey plasma to a markedly greater extent than that in dog, rabbit and rat plasma. the systemic blood pressure of anesthetized monkeys was lowered by intravenous injections of this compound which also reduced plasma renin activity and concentration of angiotensins. kri-1177 appears to selectively inhibit primate renin activity, thereby producing hypotension. | 1986 | 3536533 |
| lifetime reproductive success in female japanese macaques. | lifetime reproductive success, measured by the number of offspring surviving to age five, varied from 0 to 10 in a group of 33 provisioned female japanese macaques. of the three contributors to reproductive success, the number of reproductive years, fecundity per year and survivorship of offspring to reproductive age, the first accounted for two-thirds of the variation. fecundity per year and survivorship were negatively correlated, indicating reproductive costs of reducing interbirth interval. ... | 1986 | 3583151 |

| [experimental study of intraneural circulatory changes in axonal de- and regeneration]. | two experimental studies were made of intraneural circulatory change on axonal de- and regeneration using median and ulnar nerves of the japanese monkey. experiment 1: epineural suture was performed on one side, and fascicular suture was performed on the opposite side by removing the interfascicular epineurium. the regenerated axons in the fascicular suture group were fewer in number and smaller in diameter than those in the epineural suture group; this may have been the result of destruction of ... | 1987 | 3624964 |
| representation of the main branches of the facial nerve within the facial nucleus of the japanese monkey (macaca fuscata). | the facial nucleus of the japanese monkey was divided cytoarchitectonically into the ventral, medial, intermediate, dorsal and lateral divisions. when horseradish peroxidase (hrp) was applied to the inferior labial, cervical or posterior auricular branch of the facial nerve, hrp-labeled neurons were seen in the lateral, ventral or medial division of the facial nucleus, respectively. after applying hrp to the anterior auricular-zygomatico-orbital branch, labeled neurons were observed mainly in th ... | 1987 | 3627564 |
| electrophysiologic properties differ in the ventricular endocardium and epicardium of the japanese monkey. | we measured action potential duration (apd) from the endocardium (endo) and epicardium (epi) of the left ventricular free wall in japanese monkey hearts and found that the apd of endo is significantly longer than that of epi at a stimulus cycle length of 1500 msec in normal tyrode solution (control condition). we then hypothesized that shorter apd of epi results from greater outward pump current and that the difference in the current may be due to a difference in membrane na,k-atpase activity be ... | 1987 | 3655590 |
