New research reveals that the vertebrate head mesoderm evolved from a distinct ancient mesoderm, challenging traditional views on the evolution of the vertebrate skull. Advanced microscopy techniques showed that the head mesoderm in lamprey embryos is fundamentally different from somites, indicating an early divergence in vertebrate evolution. Scientists are examining the development of lamprey embryos to shed light on the origin of the vertebrate head, which could enhance our understanding of ancestral vertebrates. The origins of the vertebrate skull remain a subject of much debate amongst evolutionary biologists. There are those who argue that the development of the vertebrate head can be attributed to alterations in the segmented parts of the body, like the vertebrae and somites. In contrast, some scientists hold the view that the vertebrate head emerged as a distinct, non-segmented body part, not connected to the commonly seen embryonic segments known as somites. Interestingly, previous studies on embryos have revealed the presence of some vestiges of somites in the head mesoderm (e.g., head cavities and somitomeres). However, homology between trunk somites and such head segments has been controversial. The failure to understand the evolutionary origins of the vertebrate head is also attributable to the lack of studies on extant species such as lampreys, which are known to share several traits with fossil jawless vertebrates and retain primitive traits related to the head mesoderm. While some studies have focused on the embryonic morphology of lampreys, they have often fallen short because of challenges like tissue destruction and acidic fixation during examination, making it difficult to observe the formation of head mesoderm and trunk somites. Recent Advances in Research Now, however, a research team led by Assistant Professor Takayuki Onai from the University of Fukui, Japan, has utilized advanced techniques like transmission electron microscopy and serial block-face scanning electron microscopy (SBF-SEM) to understand the development of the head mesoderm and somites in lamprey embryos. The researchers also analyzed the morphology and gene expression patterns of cephalochordate and hemichordate (both being invertebrates) to understand the origins of somites and head mesoderm from an evolutionary perspective. These primitive jawless fish could hold clues to the evolutionary origin of vertebrate heads, as evidenced by detailed embryological analyses. Credit: Takayuki Onai from University of Fukui This paper was recently published in the journal iScience, and is co-authored by Dr. Noritaka Adachi from Aix-Marseille Université, Dr. Hidetoshi Urakubo from the National Institute for Physiological Sciences (NIPS), Dr. Fumiaki Sugahara from Hyogo Medical University, Dr. Toshihiro Aramaki from Osaka University, Dr. Mami Matsumoto from NIPS and Nagoya City University, and Dr. Nobuhiko Ohno from NIPS and Jichi Medical University. To clarify the presence or absence of somites in the head mesoderm during the early stages of diversification, the researchers focused on rosettes, which are major somite patterns and are important for the subsequent development of vertebrae. Their initial observations of lamprey embryos showed that the tissue closely related to the formation of facial muscles and other elements of the skull, known as the head mesoderm, did have cell clusters with features similar to somite rosettes. To clarify if these cell clusters were indeed rosettes, they conducted ultrastructural experiments, including the SBF-SEM and gene expression analysis. This examination of the cellular morphology and gene expression revealed that the cell clusters were clearly distinct from rosettes. “The cell clusters we observed are likely lamprey-specific features, as they are not recognizable in the head mesoderm of both hagfish and shark embryos,” explains Dr. Onai. Gene Expression and Evolutionary Findings Furthermore, gene expression analysis also revealed the absence of segmental expression of somitogenesis-related genes, indicating their distinctiveness from somites. These findings indicate that the rosette pattern typically seen in somites is not necessarily the essential or most basic feature that defines the process of bodily segmentation. Moreover, the experiments provide evidence that the vertebrate head mesoderm diverged during the early phases of vertebrate evolution. Furthermore, a comparison of embryos of hemichordates (a basal deuterostome), amphioxus (a basal chordate), and vertebrates revealed that the somites likely arose from the “endomesoderm” tissue of an ancient deuterostome ancestor. The evolutionary origin of somites has been the central question in zoology for more than 150 years, and in this study, Onai et al., revealed the enigma. Regarding the evolutionary mechanism for the emergence of head mesoderm, they found that the head mesoderm emerged upon the segregation of mesodermal genes between the front and back parts (rostro-caudal axis) of organisms. “Taken together, our findings revealed a different evolutionary origin for the vertebrate head mesoderm, suggesting that it evolved from the repatterning of an ancient mesoderm and diversified even before the emergence of jawed vertebrates,” concludes Dr. Onai. In summary, the finding that the cell clusters present in the head mesoderm are distinct morphologically and molecularly from somites, favors a new model where the vertebrate head mesoderm diverged during early evolution. This sheds more light on the age-old debate on the evolution of the vertebrate head and can help us advance the understanding of our own origins.

Hendrixson Aphonopelma jacobii, a new tarantula species found in southeastern Arizona, faces threats from environmental changes and human impact, emphasizing the importance of biodiversity conservation in the region. Researchers have discovered a new species of tarantula in southeastern Arizona’s Chiricahua Mountains. Named Aphonopelma jacobii, this small, black and grey tarantula has distinctive red hairs on its abdomen and thrives in the high-elevation habitats of the Chiricahua Mountains, enduring the region’s bitterly cold winters. The discovery of this species was rather unexpected. “We often hear about new species being discovered from remote corners of Earth, but it is remarkable that these spiders are found in our own backyard, albeit in somewhat difficult-to-access areas of our backyard,” said Dr. Chris Hamilton, assistant professor at the University of Idaho and co-lead author of a study in ZooKeys that reports on the spider. “With Earth in the midst of a human-mediated extinction crisis, it is astonishing how little we know about our planet’s biodiversity, even for conspicuous and charismatic groups such as tarantulas.” A mature male Aphonpelma jacobii. Credit: Brent E. Hendrixson Biodiversity in the Chiricahua Mountains The Chiricahuas are renowned for their exceptional biodiversity and high levels of endemism. These mountains form part of the Madrean Archipelago, also known as the Madrean Sky Islands, a complex of forested mountain ranges that span the Cordilleran gap between the Colorado Plateau and the Rocky Mountains in the southwestern United States and the Sierra Madre Occidental in northwestern Mexico. These montane forest “islands”—separated from each other by low-elevation deserts and arid grasslands—have evolved in isolation, leading to the origin of numerous short-range endemic species, and resulting in a mosaic of biodiversity unlike that of any other region in the United States.

Recent studies in the Sky Island region suggest that these forests will be “pushed off” the mountains over the next several decades as temperatures and precipitation continue to increase and decrease, respectively. Organisms adapted to these cooler and more humid mountain tops—such as these spiders—will likely become extinct as suitable habitat disappears.

Jacobi Conservation Concerns and Threats Dr. Brent Hendrixson, professor at Millsaps College and co-lead author of the study adds, “These fragile habitats are also threatened by increased exurban development in the San Simon Valley and Portal areas, destructive recreational activities, and wildfires. In addition, there is some concern that these tarantulas will be exploited for the exotic pet trade due to their rarity, striking coloration, and docile disposition. We must consider the impact that unethical collectors might have on these spiders when determining the threats to this species and the implications for its conservation.” Aphonopelma jacobii is named after Michael A. Jacobi, who helped find several of the first specimens that led to the description of this new species. Significance of the Discovery “This discovery represents the 30th species of tarantula documented from the United States. Aphonopelma is the most species-diverse tarantula genus on the planet (at least for documented species). Our research adds to this number and continues to advance our understanding of the true species diversity in this incredibly interesting and important biodiversity hotspot,” Dr. Hamilton says in conclusion.

A Yale study revealed brain changes in opioid use disorder patients, including altered volume and connectivity in key brain areas and sex-specific differences, pointing to new treatment possibilities. Yale’s study identified structural and functional brain alterations in opioid use disorder patients, offering insights for tailored treatments. Scientists at the Yale School of Medicine have identified structural and functional brain changes in individuals with opioid use disorder (OUD). Using MRI and fMRI data, they observed alterations in key brain regions, including differences in connectivity and volume. These findings, recently published in Radiology, a journal of the Radiological Society of North America (RSNA), could guide the development of new treatments and shed light on the long-term impacts of opioid use. The Scope of the Opioid Epidemic Opioids are a class of drugs that include synthetic opioids such as fentanyl, prescription pain relievers like oxycodone, and illegal narcotics, including heroin. These drugs have a high potential for abuse, and opioid use is a major contributor to drug overdoses in the U.S. According to the National Institute on Drug Abuse, in 2021, approximately 2.5 million adults in the U.S. had opioid use disorder. Provisional data from the Centers for Disease Control and Prevention’s National Center for Health Statistics indicate there were an estimated 81,083 overdose deaths involving opioids in the U.S. during 2023. “We are in the midst of an opioid epidemic, with millions affected worldwide and more than 80,000 deaths related to opioid overdoses in the U.S. last year alone,” said Saloni Mehta, M.B.B.S., postdoctoral associate in the Department of Radiology and Biomedical Imaging at the Yale School of Medicine. “We need to get a better understanding of the system-level neural alterations associated with opioid use disorder.” Tensor-based morphometry (TBM) analysis of T1-weighted MRI scans shows a comparison of brain volumes in participants with opioid use disorder (OUD) and healthy control participants. Widespread volume differences are observed between participants with OUD and healthy controls when accounting for total brain volume. Specifically, the bilateral thalamus, right caudate and orbitofrontal cortex, and right medial temporal lobe show lower volume in participants with OUD compared with healthy controls. The left medial temporal lobe, brainstem, bilateral cerebellum, left insula, and right dorsal posterior cingulate cortex show greater volume in those with OUD compared with healthy controls. All results are shown at P < .05, corrected for multiple comparisons. The color scale indicates the z statistic, whereby blue to pink represents smaller volumes in the OUD group compared with healthy controls, and red to yellow represents larger volumes in the OUD group compared with healthy controls. L = left, R = right. Credit: Radiological Society of North America (RSNA) Study Design and Methodology In the study, Dr. Mehta and colleagues conducted a secondary analysis of data from the National Institutes of Health-funded Collaboration Linking Opioid Use Disorder and Sleep Study (CLOUDS), comparing participants with opioid use disorder on methadone treatment and healthy controls. The data included structural MRI and functional MRI (fMRI) exams performed between February 2021 and May 2023. Resting-state fMRI allows researchers to measure brain activity by detecting changes in blood flow. With resting state fMRI, the connectivity between neural regions—known as resting state networks—can be observed while the brain is at rest. Researchers analyzed CLOUDS structural MRI data for 103 individuals with opioid use disorder and 105 individuals from the control group. They also analyzed the resting state fMRI data on 74 participants with opioid use disorder and 100 controls. The individuals with opioid use disorder were all recently stabilized with medication for the disorder (less than 24 weeks). The median age in the group with opioid use disorder was 37 years, and 40% were women. In the control group, the median age was 27 years, and 55% were women. “Previous studies have been performed on small sample sizes, many of which included no women,” Dr. Mehta said. “Ours is a moderate sample size, approximately half of which is female.” (A) Tensor-based morphometry analysis of a T1-weighted MRI scan shows an interaction between sex and group for brain volume in the right medial prefrontal cortex when accounting for total brain volume. (B) Post hoc box plot shows the average determinant of Jacobian values from the medial prefrontal cortex cluster for each group stratified according to sex. In the healthy control group, male participants had greater volume in the medial prefrontal cortex. In the opioid use disorder (OUD) group, this pattern was reversed. The solid line in the middle of each box represents the median, and the box represents the IQR. Credit: Radiological Society of North America (RSNA) Key Findings on Brain Connectivity Whole-brain analysis revealed structural and functional alterations in opioid receptor-dense regions in the opioid use disorder group compared to healthy controls. In individuals with opioid use disorder, the thalamus and right medial temporal lobe of the brain were smaller in volume, while the cerebellum and brainstem were larger in volume than in controls. In the individuals with opioid use disorder, all these brain regions also had increased functional connectivity compared to controls. “We observed widespread increases in global connectivity in individuals with opioid use disorder,” Dr. Mehta said. “Our goal is to understand better what could have caused these alterations to inform new treatment targets.” Intrinsic connectivity distribution analysis of resting-state functional MRI scans shows a comparison of global resting-state functional connectivity between participants with opioid use disorder (OUD) and healthy control participants. Color scale gradations of yellow indicate greater global connectivity in the bilateral secondary visual areas, left thalamus, right medial temporal lobe, right cerebellum, and brainstem in participants with OUD compared with healthy controls. No clusters of reduced connectivity were observed. L = left, R = right. Credit: Radiological Society of North America (RSNA) Gender Differences in Brain Alterations The results also revealed that women in the group with opioid use disorder had smaller medial prefrontal cortex volume, compared to males in the same group. “We found that alteration patterns in the medial prefrontal cortex—a core region involved in many mental health conditions—were different between men and women in the group with opioid use disorder,” Dr. Mehta said. “This highlights the importance of assessing sex differences in opioid use disorder neuroimaging studies.” Future Directions in Research Dr. Mehta said the study builds a foundation for future research to investigate potential behavioral implications of these brain differences and whether they are permanent. “Our eventual goal is to examine how brain alterations in individuals with opioid use disorder may be linked to outcome measures,” she said.
