Early synapsids neurosensory diversity revealed by CT and synchrotron scanning

The Anatomical Record, EarlyView.
Abstract Non‐mammaliaform synapsids (NMS) represent the closest relatives of today's mammals among the early amniotes. Exploring their brain and nervous system is key to understanding how mammals evolved. Here, using CT and Synchrotron scanning, we document for the first time three extreme cases of neurosensory and behavioral adaptations that probe ...

Spatiotemporal symmetries in the disynaptic canal-neck projection [PDF]

, 2007
The vestibular system in almost all vertebrates, and in particular in humans, controls balance by employing a set of six semicircular canals, three in each inner ear, to detect angular accelerations of the head in three mutually orthogonal coordinate ...

Predicting ecology and hearing sensitivities in Parapontoporia—An extinct long‐snouted dolphin

The Anatomical Record, EarlyView.
Abstract Analyses of the cetacean (whale and dolphin) inner ear provide glimpses into the ecology and evolution of extinct and extant groups. The paleoecology of the long‐snouted odontocete (toothed whale) group, Parapontoporia, is primarily marine with its depositional context also suggesting freshwater tolerance.

Intratympanic Gentamicin Versus Labyrinthectomy: Inner Ear Sensitivity to Gentamicin and Impact on the Contralateral Labyrinth [PDF]

Clinical and Experimental Otorhinolaryngology, 2019
Objectives. To investigate the impact of labyrinthectomy and intratympanic (IT) gentamicin injections on the contralateral labyrinth, we also assessed the response of each individual semicircular canal to each IT gentamicin application. Methods.

Disparity of turbinal bones in placental mammals

The Anatomical Record, EarlyView.
Abstract Turbinals are key bony elements of the mammalian nasal cavity, involved in heat and moisture conservation as well as olfaction. While turbinals are well known in some groups, their diversity is poorly understood at the scale of placental mammals, which span 21 orders.

Guide the diagnosis and treatment of benign paroxysmal positional vertigo from the perspective of vestibular pathophysiology

Chinese Journal of Contemporary Neurology and Neurosurgery, 2019
This paper aims to explain the clinical features of benign paroxysmal positional vertigo (BPPV), the most common peripheral vertigo disease, from the view of vestibular pathophysiology.

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

The Anatomical Record, EarlyView.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Review of the anatomical basis for predicting plutonium alpha particle radiation induced osteogenic cancers

The Anatomical Record, EarlyView.
Abstract Plutonium was discovered and first synthesized in the early 1940's. Several isotopes of plutonium are used in nuclear technologies, 238Pu for heat generation and 239Pu for energy production and weapons. Both isotopes emit alpha particles, which pose a significant radiation hazard when incorporated into the body.

But how does it smell? An investigation of olfactory bulb size among living and fossil primates and other euarchontoglirans

The Anatomical Record, EarlyView.
Analysis of cranial endocast data of 181 extant and 41 fossil species from Euarchontoglires shows that there was a reduction in olfactory bulb size in Crown Primates, but that there were also subsequent reductions in various other primate clades (Anthropoidea, Catarrhini, Platyrrhini, crown Cercopithecoidea, Hominoidea).
