Brain-wide mapping of neural activity controlling zebrafish exploratory locomotion.
In the absence of salient sensory cues to guide behavior, animals must still execute sequences of motor actions in order to forage and explore. How such successive motor actions are coordinated to form global locomotion ...
A craniofacial-specific monosynaptic circuit enables heightened affective pain.
(Nature neuroscience, 2017-12)
Humans often rank craniofacial pain as more severe than body pain. Evidence suggests that a stimulus of the same intensity induces stronger pain in the face than in the body. However, the underlying neural circuitry for ...
Darwinius masillae is a strepsirrhine--a reply to Franzen et al. (2009).
(Journal of human evolution, 2010-11)
Stem members of Platyrrhini are distinct from catarrhines in at least one derived cranial feature.
(Journal of human evolution, 2016-11)
The pterion, on the lateral aspect of the cranium, is where the zygomatic, frontal, sphenoid, squamosal, and parietal bones approach and contact. The configuration of these bones distinguishes New and Old World anthropoids: ...
Smooth operator: The effects of different 3D mesh retriangulation protocols on the computation of Dirichlet normal energy.
(American journal of physical anthropology, 2017-05)
Dirichlet normal energy (DNE) is a metric of surface topography that has been used to evaluate the relationship between the surface complexity of primate cheek teeth and dietary categories. This study examines the effects ...
Auditory morphology and hearing sensitivity in fossil New World monkeys.
(Anatomical record (Hoboken, N.J. : 2007), 2010-10)
In recent years it has become possible to investigate the hearing capabilities in fossils by analogy with studies in living taxa that correlate the bony morphology of the auditory system with hearing sensitivity. In this ...
Hands of early primates.
(American journal of physical anthropology, 2013-12)
Questions surrounding the origin and early evolution of primates continue to be the subject of debate. Though anatomy of the skull and inferred dietary shifts are often the focus, detailed studies of postcrania and inferred ...
Evolution of postural diversity in primates as reflected by the size and shape of the medial tibial facet of the talus.
(American journal of physical anthropology, 2015-05)
Comprehensive quantification of the shape and proportions of the medial tibial facet (MTF) of the talus (=astragalus) has been lacking for Primates and their closest relatives. In this study, aspects of MTF form were quantified ...
Interspecific scaling patterns of talar articular surfaces within primates and their closest living relatives.
(Journal of anatomy, 2014-02)
The articular facets of interosseous joints must transmit forces while maintaining relatively low stresses. To prevent overloading, joints that transmit higher forces should therefore have larger facet areas. The relative ...
First virtual endocasts of adapiform primates.
(Journal of human evolution, 2016-10)
Well-preserved crania of notharctine adapiforms from the Eocene of North America provide the best direct evidence available for inferring neuroanatomy and encephalization in early euprimates (crown primates). Virtual endocasts ...
