Technological revolutionary changes have boosted mobile learning’s evolution from supplementary material for teaching to a flexible, strategic, and convenient resource, driving new paths in higher education. With global increases in wireless internet access and the advent of highly functional smartphones and tablets, which have impacted the rise in...

Morphological evolution of the vertebrate skull has been explored across a wide range of tetrapod clades using geometric morphometrics, but the application of these methods to teleost fishes, accounting for roughly half of all vertebrate species, has been limited. Here we present the results of a study investigating three-dimensional morphological...

Over the past year, defined by the COVID-19 pandemic, we have witnessed a boom in applying key emerging technologies in education. In such challenging situations, technology and education expanded their work together to strengthen and interactively impact the learning process in the online higher education context. From a pedagogical perspective, e...

Morphological evolution of the vertebrate skull has been explored across a wide range of tetrapod clades, but teleost fishes, accounting for roughly half of all vertebrate species, have largely been overlooked. Here we present the results of a study investigating three-dimensional morphological evolution across 114 species of Pelagiaria, a morpholo...

The detailed description of processing workflows in Structure from Motion (SfM) surveys using unmanned aerial vehicles (UAVs) is not common in geomorphological research. One of the aspects frequently overlooked in photogrammetric reconstruction is image characteristics. In this context, the present study aims to determine whether the format or prop...

p class="VARAbstract">During the 19^th and 20^th centuries, numerous museums, scientific societies, and royal academies were founded in Europe and America. In this scenario, the Anthropological Museum Montané was founded in Havana, Cuba. Its collection has grown over the years, thanks to researchers, antiquarians, and amateurs....

The impressions left by the vascular system on the surface of the skull, like those of the middle meningeal vessels, the dural venous sinuses, and the emissary veins, are a unique source of vascular and anatomical evidence when working with osteological collections, as is the case with bioarchaeological, forensic, and paleoanthropological investiga...

Objectives The diploic channels are bony passages of veins, running within frontal, parietal, and occipital bones. In this study, we investigate ontogenetic changes of these channels in a sample of nonadult and adult modern humans. Materials and methods Using computed tomography scans of dried crania, we provide quantitative comparisons of lumen s...

The endocranial cavity is a major source of information for the assessment of brain morphology in extinct species. Digital molds of the endocranium can be reconstructed from fossil remains. In paleoneurology, these so-called endocasts are examined using shape analysis and multivariate statistical methods to quantify differences among species and in...

The vascular system is distributed throughout the cerebral, connective, and bony elements of the braincase, and it supplies an anatomical connection between these three components of the endocranial morphology. The imprints and traces left by arteries and veins in the bone thickness and surface can be useful in the analysis of vascular features in...

According to the descriptions supplied by Columbus and the chroniclers of the Indies, the Aboriginal groups of Central & South America, and Caribe, applied different techniques to transform the morphology of the skull. The pre-Columbian’s deformed skulls from Cuba, present an oblique-tabular fronto-occipital artificial cranial warp, which is a cult...

Cranial bone thickness varies among modern humans, and many factors influencing this variability remain unclear. Growth hormones and physical activity are thought to influence the vault thickness. Considering that both systemic factors and energy supply influence the vascular system, and taking into account the structural and biomechanical interact...

Many aspects of human biology can be reconstructed from skeletal and fossil remains. The endocranial vasculature runs through cerebral, connective, and bone elements, where it is influenced by the functional and structural relationships among these different components of the endocranial system. The imprints and traces of these vessels can be used...

Objectives: The diploic channels appear to be more developed in humans than in nonhuman primates, suggesting they may be relevant in evolutionary biology. This study is aimed at providing a segmentation procedure for diploic channels and CT analysis, a quantitative description of their variation in modern humans, and paleoanthropological case-stud...

The diploic channels were identified in mammals over 200 years ago, and subsequently described in humans by Gilbert Breschet in 1829. However, diploic veins are scarcely considered in current anatomical studies. This vascular network appears to be more developed in humans than in non-human primates, which suggests this topic may be relevant in evol...

Recent analyses indicate that the precuneus is one of the main centres of integration in terms of functional and structural processes within the human brain. This neuroanatomical element is formed by different subregions, involved in visuo-spatial integration, memory and self-awareness. We analysed the midsagittal brain shape in a sample of adult h...
