| disynaptic pyramidal excitation in forelimb motoneurons mediated via c(3)-c(4) propriospinal neurons in the macaca fuscata. | in contrast to findings in the cat, it recently has been shown that disynaptic pyramidal epsps only rarely are observed in forelimb motoneurons of the macaque monkey in the intact spinal cord or after a corticospinal transection in c(5). this finding has been taken to indicate that the disynaptic pyramidal excitatory pathway via c(3)-c(4) propriospinal neurons (pns) is weakened through phylogeny when the monosynaptic cortico-motoneuronal connection has been strengthened. we reinvestigate this is ... | 1999 | 10601484 |

| interference from irrelevant features on visual discrimination by macaques (macaca fuscata): a behavioral analogue of the human stroop effect. | to study the operation of selective attention in a conflict situation with automatic processes, we trained 4 japanese macaques (macaca fuscata) extensively on a manual go/no-go task. the monkey had to discriminate either the color, shape, motion direction, or location of a visual stimulus. in each trial, the behavioral meaning of the relevant feature (go or no-go) could either be congruent or incongruent with irrelevant features of the same stimulus. reaction times were slowed, and error rates i ... | 2000 | 10913998 |
| structural variations of the vwa locus in humans and comparison with non-human primates. | the humvwa locus was examined in 160 samples from the japanese population. a total of 142 fragments were sequenced, and the counterpart sequences were also determined in non-human primates. in humans, 10 different alleles were found; they could be grouped into seven allelic classes based on the total number of repeats. no variation was observed in the alleles 17, 18 and 19, which showed consensus sequence structures and in the allele 14, which showed a different structure. new variation was foun ... | 2000 | 10978593 |
| evolution of the abo blood group gene in japanese macaque. | we determined 5 sequences of japanese macaque abo blood group gene exon 7 (ca. 0.5 kb) and 2 sequences for exon 5 and intron 6 (ca. 1.7 kb). we compared those data with published sequences of other old world monkey species, and the results suggest that alleles a and b were polymorphic in the ancestral species of macaques, and that b type allele evolved independently in macaque and baboon lineages. | 2000 | 10984838 |
