| parity-related differences in suckling behavior and nipple preference among free-ranging japanese macaques. | suckling behavior of primiparae in free-ranging japanese macaques (macaca fuscata) was compared with that of multiparae at jigokudani monkey park, the shiga heights, nagano prefecture, japan, from april 1984 to 1994. the estimated rates of milk secretion in a single preferred nipple among primiparae were lower than those among multiparae from birth to 5 months of age. milk secretion capabilities of primiparous mothers, hence, appear to be inferior to those of multiparous mothers. in nutritive su ... | 1997 | 9261514 |

| perceptual salience of acoustic features of japanese monkey coo calls. | smooth early high (seh) and smooth late high (slh) coo calls differ in the temporal location of a frequency inflection and are generally used in different situations. coo quality is also influenced by additional features, such as relative harmonic level, which may have communicative significance. the authors used multidimensional scaling to analyze the perceptual similarity of seh and slh coos. neither the temporal position of the frequency inflection nor caller identity could explain the coo gr ... | 1997 | 9286095 |
| rapid decalcification of temporal bones with preservation of ultrastructure. | decalcification of temporal bones, especially from primates, has routinely required long periods of time and has been a major deterrent to many types of morphological studies. in this investigation, temporal bones from the monkey, macaca fuscata, were decalcified with ethylene diamine tetraacetic acid (edta) in a microwave oven. to isolate effects of microwaves on decalcification, tissue was fixed and embedded using routine methods; only decalcification was carried out in the microwave oven. the ... | 1997 | 9307313 |

| representation of objective similarity among three-dimensional shapes in the monkey. | humans have been recently shown to represent parameterized three-dimensional objects in a manner that preserves relative similarities (as measured by parameter-space distances) among the objects (cutzu and edelman 1996). we show that the representation of objects in the monkey visual system is similarly faithful to the parametric variation built into the stimulus set. a monkey (macaca fuscata) performed a delayed matching-to-sample task with 28 images (4 views x 7 objects). stimuli in each of th ... | 1998 | 9485583 |
| matching of acoustic features during the vocal exchange of coo calls by japanese macaques | a central issue in studies of vocalizations of non-human primates is the extent of their plasticity. japanese macaques, macaca fuscata, frequently utter coo calls and exchange these calls with other group members to maintain contact vocally. i conducted a playback experiment to examine whether monkeys that respond vocally match the acoustic features of their reply to those of the calls they have heard. six to eight stimulus calls with different acoustic properties in terms of fundamental frequen ... | 1998 | 9514664 |
| dopamine synthesizing enzymes in paraventricular hypothalamic neurons of the human and monkey (macaca fuscata). | using immunohistochemistry, we demonstrated that paraventricular hypothalamic neurons immunoreactive for tyrosine hydroxylase (th) were not immunopositive for the second step catecholamine synthesizing enzyme l-amino acid decarboxylase (aadc) in the human and monkey macaca fuscata. in the latter species, they were not immunoreactive for dopamine. it is most likely that primate paraventricular th-containing neurons do not synthesize dopamine. | 1998 | 9535098 |
