“…However, another potential contributor could be differences in the stimuli produced by cocaine-exposed versus unexposed litters. For example, pup urine is a strong stimulus that elicits MB (Londei et al, 1989), and in this study we demonstrate significant differences in the urine composition between cocaine-naïve and exposed pups. Also, ultrasonic vocalizations are altered by prenatal cocaine in rats (Cox et al, 2012, Lippard et al, 2015, McMurray et al, 2013) in ways that are qualitatively similar to exposed human infants (Zeskind et al, 2014).…”

“…Once the animal habituated to the object, a cotton swab laced with 50 μl of odorant or urine was introduced. We tested pup urine because mouse fetuses laced with pup urine stimulate greater frequency of maternal behaviors than fetuses treated with water, indicating that mouse pup urine contains odorants or pheromones that elicit maternal behavior (Londei et al , 1989). When a female mouse detected the new odorant, she sniffed the cotton swab a greater number of times than she did when the swab only contained water.…”

“…Furthermore, in a modified Y-maze test, postpartum female mice retrieve young pups by chemosensory cues from the pups without the use of visual or auditory clues (Smotherman et al , 1974). Moreover, in the pup retrieval assay, female mice prefer fetuses treated with pup urine (Londei et al , 1989). The importance of chemoreception for maternal behaviors is also supported by studies showing that olfactory bulbectomy eliminates maternal behaviors (Gandelman et al , 1971, 1972; Zarrow et al , 1971).…”

“…reproductive state, experience or prior drug exposure, the maternal behaviour of altricial rodents is also a function of the sensory information provided by the pups [25,[42][43][44][45][46]. In mice, cues related to pup urine influence both retrieving and licking behaviours [47], whereas pup ultrasonic calls are involved in stimulating both retrieving and nest-building activities [48; 49, see after]. Recent data suggest that neonatal undernutrition may affect mother-infant interaction by interfering with urogenital responses to maternal anogenital licking of newborn rats [12].…”

“…A probable reason why urinary H-2 odortypes are not apparent when infant mice are tested in the Y-maze can be found in the fact that infant mice characteristically do not urinate spontaneously but are stimulated to do so when the mother licks them (9) and, thereby, undoubtedly ingests the odortype-expressing urine that serves to distinguish her own pups from others (10). Since urine serves as a chemical signal between pups and mother (11), it is likely that MHCregulated odortypes provide a basis for this recognition.…”
