The current study aimed to examine the nature of the coupling between olfactory stimuli from the mother and the newborn's crawling and rooting (exploratory movements of the head). To examine the coupling, the crawling and rooting behavior of 28 2\u2010day\u2010old newborns were studied while they were supported prone on a mobility device shaped like a mini skateboard, the Crawliskate\u00ae, their head positioned directly on top of a pad infused with either their mother's breast odor (Maternal) or the odor of water (Control). Video and 3D kinematic analyses of the number and types of limb movements and quantification of displacement across the surface revealed that newborns are significantly more efficient crawlers when they smell the maternal odor, moving greater distances although performing fewer locomotor movements. In addition, the newborns made significantly more head rooting movements in the presence of the maternal odor. These findings suggest that the circuitry underlying quadrupedal locomotion and exploratory movements of the head is already adaptable to olfactory information via higher brain processing. Moreover, the coupling between olfaction and the two action systems, locomotion and rooting, is already differentiated. As crawling enables the newborn to move toward the mother's breast immediately after birth and facilitates mother\u2013infant interaction, the results of this study highlight the potential value of using maternal odors to stimulate mobility in infants at risk of motor delay and\/or deprived of this odor when born prematurely.<\/jats:p>","DOI":"10.1111\/desc.13061","type":"journal-article","created":{"date-parts":[[2020,11,11]],"date-time":"2020-11-11T02:10:48Z","timestamp":1605060648000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":32,"title":["Newborn crawling and rooting in response to maternal breast odor"],"prefix":"10.1111","volume":"24","author":[{"given":"Charlotte","family":"Hym","sequence":"first","affiliation":[{"name":"Integrative Neuroscience and Cognition Center Universit\u00e9 de Paris \u2013 CNRS Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vincent","family":"Forma","sequence":"additional","affiliation":[{"name":"Integrative Neuroscience and Cognition Center Universit\u00e9 de Paris \u2013 CNRS Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David I.","family":"Anderson","sequence":"additional","affiliation":[{"name":"Marian Wright Edelman Institute San Francisco State University San Francisco CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jo\u00eblle","family":"Provasi","sequence":"additional","affiliation":[{"name":"Laboratoire CHArt Ecole Pratique des Hautes Etudes Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lionel","family":"Granjon","sequence":"additional","affiliation":[{"name":"Integrative Neuroscience and Cognition Center Universit\u00e9 de Paris \u2013 CNRS Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Viviane","family":"Huet","sequence":"additional","affiliation":[{"name":"Integrative Neuroscience and Cognition Center Universit\u00e9 de Paris \u2013 CNRS Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emilie","family":"Carpe","sequence":"additional","affiliation":[{"name":"Integrative Neuroscience and Cognition Center Universit\u00e9 de Paris \u2013 CNRS Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4400-783X","authenticated-orcid":false,"given":"Caroline","family":"Teulier","sequence":"additional","affiliation":[{"name":"Universit\u00e9 Paris\u2010Saclay CIAMS Orsay France"},{"name":"Universit\u00e9 d'Orl\u00e9ans CIAMS Orl\u00e9ans France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karine","family":"Durand","sequence":"additional","affiliation":[{"name":"Developmental Ethology and Cognitive Psychology Group Center for Taste, Smell and Feeding Science UMR 6265 CNRS\u2010Universit\u00e9 de Bourgogne\u2010Franche\u2010Comt\u00e9 Dijon France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Benoist","family":"Schaal","sequence":"additional","affiliation":[{"name":"Developmental Ethology and Cognitive Psychology Group Center for Taste, Smell and Feeding Science UMR 6265 CNRS\u2010Universit\u00e9 de Bourgogne\u2010Franche\u2010Comt\u00e9 Dijon France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marianne","family":"Barbu\u2010Roth","sequence":"additional","affiliation":[{"name":"Integrative Neuroscience and Cognition Center Universit\u00e9 de Paris \u2013 CNRS Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,12,5]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/cercor\/bhx167"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.earlhumdev.2010.07.003"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1467-8624.2008.01241.x"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/dev.21174"},{"key":"e_1_2_8_6_1","unstructured":"Barbu\u2010Roth M.
