Constructing the rodent stereotaxic brain atlas: a survey.

The stereotaxic brain atlas is a fundamental reference tool commonly used in the field of neuroscience. Here we provide a brief history of brain atlas development and clarify three key conceptual elements of stereotaxic brain atlasing: brain image, atlas, and stereotaxis. We also refine four technical indices for evaluating the construction of atlases: the quality of staining and labeling, the granularity of delineation, spatial resolution, and the precision of spatial location and orientation. Additionally, we discuss state-of-the-art technologies and their trends in the fields of image acquisition, stereotaxic coordinate construction, image processing, anatomical structure recognition, and publishing: the procedures of brain atlas illustration. We believe that the use of single-cell resolution and micron-level location precision will become a future trend in the study of the stereotaxic brain atlas, which will greatly benefit the development of neuroscience.

From Ancient Texts to Digital Imagery: A Brief History on the Evolution of Anatomic Illustrations.

In a time when social isolation heavily relies on the use of digital representation, photography, and e-books, it is easy to take for granted the impact imagery has on our society and the pedagogical purposes of illustration, particularly in the teaching of surgery. Illustrations after all are the basis of all anatomical atlases and are quintessential tools that allow for an expedient and thorough understanding of concepts underlying the fabric of the human body. Yet, surgery has not always been taught with an atlas. Illustrations, much like surgery, have seen an incredible transformative process spanning across the ages to achieve their status in modern medicine. Through this brief review, we will not only glean an understanding of the evolution of anatomical illustrations but also the social context in which surgery has also evolved throughout history.

Evolution of Human Brain Atlases in Terms of Content, Applications, Functionality, and Availability.

Human brain atlases have been evolving tremendously, propelled recently by brain big projects, and driven by sophisticated imaging techniques, advanced brain mapping methods, vast data, analytical strategies, and powerful computing. We overview here this evolution in four categories: content, applications, functionality, and availability, in contrast to other works limited mostly to content. Four atlas generations are distinguished: early cortical maps, print stereotactic atlases, early digital atlases, and advanced brain atlas platforms, and 5 avenues in electronic atlases spanning the last two generations. Content-wise, new electronic atlases are categorized into eight groups considering their scope, parcellation, modality, plurality, scale, ethnicity, abnormality, and a mixture of them. Atlas content developments in these groups are heading in 23 various directions. Application-wise, we overview atlases in neuroeducation, research, and clinics, including stereotactic and functional neurosurgery, neuroradiology, neurology, and stroke. Functionality-wise, tools and functionalities are addressed for atlas creation, navigation, individualization, enabling operations, and application-specific. Availability is discussed in media and platforms, ranging from mobile solutions to leading-edge supercomputers, with three accessibility levels. The major application-wise shift has been from research to clinical practice, particularly in stereotactic and functional neurosurgery, although clinical applications are still lagging behind the atlas content progress. Atlas functionality also has been relatively neglected until recently, as the management of brain data explosion requires powerful tools. We suggest that the future human brain atlas-related research and development activities shall be founded on and benefit from a standard framework containing the core virtual brain model cum the brain atlas platform general architecture.

Medical Illustration in the Era of Cardiac Surgery.

This article reviews the collaboration between clinician and illustrator throughout the ages while highlighting the era of cardiac surgery. Historical notes are based on Professor Sanjib Kumar Ghosh's extensive review, literature searches, and the archives of the Johns Hopkins University Department of Art as related to Medicine in Baltimore. Personal communications were explored with medical illustrators and medical practitioners, many of whom are colleagues and trainees, to further chronicle the history of medical illustration and education in the era of cardiac surgery. Medical illustrators use their talents and expressive ideas to demonstrate procedures and give them life. These methods are (1) hovering technique; (2) hidden anatomy, ghosted views, or transparency; (3) centrally focused perspective; (4) action techniques to give life to the procedure; (5) use of insets to highlight one part of the drawing; (6) human proportionality using hands or known objects to show size; and (7) step-by-step educational process to depict the stages of a procedure. Vivid examples showing these techniques are demonstrated. The result of this observational analysis underscores the importance of the collaboration between clinician and illustrator to accurately describe intricate pathoanatomy, three-dimensional interrelated anatomic detail, and complex operations. While there are few data to measure the impact of the atlas on medical education, it is an undeniable assertion that anatomical and surgical illustrations have helped to educate and train the modern-day surgeon, cardiologist, and related health-care professionals.

Photograph as Skin, Skin as Wax: Indexicality and the Visualisation of Syphilis in Fin-de-Siècle France The William Bynum Prize Essay.

In early twentieth-century France, syphilis and its controversial status as a hereditary disease reigned as a chief concern for physicians and public health officials. As syphilis primarily presented visually on the surface of the skin, its study fell within the realms of both dermatologists and venereologists, who relied heavily on visual evidence in their detection, diagnosis, and treatment of the disease. Thus, in educational textbooks, atlases, and medical models, accurately reproducing the visible signposts of syphilis - the colour, texture, and patterns of primary chancres or secondary rashes - was of preeminent importance. Photography, with its potential claims to mechanical objectivity, would seem to provide the logical tool for such representations. Yet photography's relationship to syphilographie warrants further unpacking. Despite the rise of a desire for mechanical objectivity charted in the late nineteenth century, artist-produced, three-dimensional, wax-cast moulages coexisted with photographs as significant educational tools for dermatologists; at times, these models were further mediated through photographic reproduction in texts. Additionally, the rise of phototherapy complicated this relationship by fostering the clinical equation of the light-sensitive photographic plate with the patient's skin, which became the photographic record of disease and successful treatment. This paper explores these complexities to delineate a more nuanced understanding of objectivity vis-à-vis photography and syphilis. Rather than a desire to produce an unbiased image, fin-de-siècle dermatologists marshalled the photographic to exploit the verbal and visual rhetoric of objectivity, authority, and persuasion inextricably linked to culturally constructed understandings of the photograph. This rhetoric was often couched in the Peircean concept of indexicality, which physicians formulated through the language of witness, testimony, and direct connection.

An ancestor of the stereotactic atlases: the Tabulae Anatomicae of Bartolomeo Eustachio.

The authors report the history of the Tabulae Anatomicae of Bartolomeo Eustachio (ca. 1510-1574). In the tables, the anatomical illustrations were drawn inside a numerical frame, with pairs of numbers on the y- and x-axes to identify single anatomical details in the reference table. The measures and the references could be calculated using the graduated margins divided by 5 units for each the x-axis and y-axis. The Tabulae Anatomicae can be considered a precursor to modern anatomical reference systems that are the basis of studies on cerebral localization mainly used for stereotactic procedures.

Jean Talairach: a cerebral cartographer.

Although French psychiatrist-turned-neurosurgeon Jean Talairach (1911-2007) is perhaps best known for the stereotaxic atlas he produced with Pierre Tournoux and Gábor Szikla, he has left his mark on most aspects of modern stereotactic and functional neurosurgery. In the field of psychosurgery, he expressed critique of the practice of prefrontal lobotomy and subsequently was the first to describe the more selective approach using stereotactic bilateral anterior capsulotomy. Turning his attention to stereotaxy, Talairach spearheaded the team at Hôpital Sainte-Anne in the construction of novel stereotaxic apparatus. Cadaveric investigation using these tools and methods resulted in the first human stereotaxic atlas where the use of the anterior and posterior commissures as intracranial reference points was established. This work revolutionized the approach to cerebral localization as well as leading to the development of numerous novel stereotactic interventions by the Sainte-Anne team, including tumor biopsy, interstitial irradiation, thermal ablation, and endonasal procedures. Together with epileptologist Jean Bancaud, Talairach invented the field of stereo-electroencephalography and developed a robust scientific methodology for the assessment and treatment of epilepsy. In this article the authors review Talairach's career trajectory in its historical context and in view of its impact on modern stereotactic and functional neurosurgery.

Comparative Studies of Two Major Sets of Tibetan Medical Paintings: A Historical Perspective.

Tibetan medicine, one of the time-honored medical systems in the world, has increasingly been receiving attention the world over. Tibetan medical paintings (TMP, tib. Sman thang) has become one of the focal points in the studies of this medical system. To date, there are many atlases and publications on TMP, which are principally based on the two major sets of TMP series existing today in the world, the Lhasa set and the Buryat set. It has been found that the Buryat set is based on the Lhasa set, which was brought in late 19th to the first half of the 20th century from Tibet to Buryatia, Russia. A careful investigation on the basic structure of the two sets reveals that there are many differences between the two sets of paintings, including the total number of the paintings involved, of which some are missing in one set, the details of the captions of some of the paintings, the existence of the 80th painting and its supervisor, and the overall order of the entire set, etc. The details of the differences are elaborated and discussed, and the prospective of developing the research to arrive at a standard and perfect TMP set in the future is also analyzed and anticipated.

Nerve Surgeons' Assessment of the Role of Eduard Pernkopf's Atlas of Topographic and Applied Human Anatomy in Surgical Practice.

BACKGROUND: Pernkopf's atlas of Anatomy contains anatomical plates with detailed images of the peripheral nerves. Its use is controversial due to the author's association with the "Third Reich" and the potential depiction of victims of the Holocaust. The ethical implications of using this atlas for informing surgical planning have not been assessed. OBJECTIVE: To (1) assess the role of Pernkopf's atlas in nerve surgeons' current practice and (2) determine whether a proposal for its ethical handling may provide possible guidance for use in surgery and surgical education. METHODS: Members of American Society for Peripheral Nerve and PASSIO Education (video-based learning platform) were surveyed and 182 responses collected. The survey introduced the historical origin of Pernkopf's atlas, and respondents were asked whether they would use the atlas under specific conditions to serve as a recommendation for its ethical handling. An anatomical plate comparison between Netter's and Pernkopf's atlases was performed to compare anatomical accuracy and surgical utility. RESULTS: Fifty-nine percent of respondents were aware of Pernkopf's atlas, with 13% currently using it. Aware of the historical facts, 69% were comfortable using the atlas, 15% uncomfortable, and 17% undecided. Additional information on conditions for an ethical approach to the use of the atlas led 76% of those "uncomfortable" and "undecided" to becoming "comfortable" with use. CONCLUSION: While the use of Pernkopf's atlas remains controversial, a proposal detailing conditions for an ethical approach in its use provides new guidance in surgical planning and education.

The AFIP/ARP Atlases of Pathology Past, Present, and Future.

The AFIP (Armed Forces Institute of Pathology) Atlases (Fascicles) have been in continuous publication for nearly 75 years and have enjoyed a highly regarded reputation for their excellence. Throughout this time period, more than 130 volumes, encompassing the 1st to 4th series have been published. Since their inception in the 1940's, the Fascicles have evolved from loose-leafed atlases illustrated with black and white images, to hardbound monographs with full color images and expansion of scope, including relevant clinical information, cytopathology, and the most recent advances in immunohistochemistry and molecular diagnostics. Each of the volumes undergoes a rigorous review process by the Editor-in-Chief, Associate Editors, members of the Editorial Advisory Board, and external reviewers. The 5th series, under the editorial direction of Drs. Elizabeth Montgomery and Jason Hornick, is well underway and will include an Epub version and a virtual slide box, in addition to the hardbound book. The Atlases of Nontumor Pathology will also continue to be published. With the closure of the AFIP in 2011, the American Registry of Pathology (ARP) has assumed full responsibility for the publication of both the Tumor and Nontumor Fascicles.

Matthew baillie's specimens and engravings.

In 1799, Matthew Baillie, William Hunter's nephew, published his famous atlas of pathology. It was entitled A Series of Engravings Accompanied with Explanations which are Intended to Illustrate the Morbid Anatomy of Some of the Most Important Parts of the Human Body. The present study aims to match the illustrations to extant specimens in the collections of William and John Hunter, preserved at the University of Glasgow and at the Royal College of Surgeons of England respectively. Baillie's book contains 10 fasciculi, consisting of 73 plates and 206 figures. The specimens Baillie illustrated came from his own collection and those of ten others, including his uncles, William and John Hunter. The book was illustrated by William Clift and engraved by James Basire, William Skelton and James Heath. Excluding eight illustrations of intestinal worms where the provenance of the specimens is uncertain, a total of 98 specimens from William Hunter's collection were illustrated in 104 figures. Eight of the specimens were calculi impossible to identify specifically. Excluding worms and calculi, 72 of William Hunter's specimens illustrated by Baillie are extant in the Hunterian Collection at the University of Glasgow. All but one of the 20 specimens illustrated that had belonged to John Hunter were identified in the on-line catalog of the Royal College of Surgeons of England. Baillie's own collection was destroyed when the Royal College of Surgeons of England was bombed in 1941. Baillie is credited with being the first to produce an illustrated systematic textbook of morbid anatomy and probably the first to illustrate emphysema and transposition of the great vessels. His book, however, was not comprehensive. It did not cover a number of topics such as muscles and bones and there is little coverage of the nervous system. Baillie's book, however, was an original concept as an atlas of morbid anatomy and showed his deep insight into pathology. Clin. Anat. 31:622-631, 2018. © 2017 Wiley Periodicals, Inc.

Medical Students' Assessment of Eduard Pernkopf's Atlas: Topographical Anatomy of Man.

INTRODUCTION: To date, there has been no study examining the perceptions of first-year medical students regarding Eduard Pernkopf's atlas, particularly during their study of gross anatomy and prior to coursework in medical ethics. We present a discussion of Pernkopf's Atlas: Topographical Anatomy of Man from the perspective of U.S. medical students, and sought to determine whether medical students view Pernkopf's Topographical Anatomy of Man as a resource of greater accuracy, detail, and potential educational utility as compared to Netter's Atlas of Human Anatomy. METHODS: The entire first-year class at Drexel University College of Medicine (265 students) was surveyed at approximately the midpoint of their gross anatomy course and 192 responses were collected (72% response rate). RESULTS: Of these, 176 (95%) were unaware of the existence of Pernkopf's atlas. Another 71% of students found the Pernkopf atlas more likely complete and accurate, whereas 76% thought the Netter atlas more useful for learning (p<.001). When presented with a hypothetical scenario in which the subjects used in creating Pernkopf's atlas were donated, or unclaimed, but with knowledge that Pernkopf was an active member of the Nazi party, 133 students (72%) retained their original position (p=.001). About 94% desired discussion of Pernkopf within a medical school bioethics course. The relationship between level of self-reported knowledge and whether or not students would advocate removal of the atlas was statistically significant (p=.013). CONCLUSION: Discussing ethical violations in medical history, especially the Pernkopf atlas, must attain a secure place in medical school curricula, and more specifically, within a bioethics course.
