Olfactory Nerve Schwannoma: A Case Report and Review of the Literature
Schwannomas are benign tumors, which arise from the Schwann cells of the central or peripheral nerves. They form 8% of all intracranial tumors and most of the cases arise from vestibular division of the 8th cranial nerve.

Mechanisms of pattern processing in olfactory bulb-like circuits [PDF]
The scope of brain research spans several orders of magnitude ranging from small groups of amino acid residues in ion channels to fMRI signals reflecting activity averaged over thousands of neurones. From a theoreticians point of view very interesting

Mucormycosis is an opportunistic fungal infection involving among others the paranasal sinuses, nasal fossa and brain parenchyma. Mucor can invade the brain parenchyma by either contiguous spread from the paranasal sinuses or through vascular invasion ...

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

An Olfactory Receptor Pseudogene whose Function emerged in Humans [PDF]
Human olfactory receptor, hOR17-210, is identified as a pseudogene in the human genome. Experimental data has shown however, that the gene product of cloned hOR17-210 cDNA was able to bind an odorant-binding protein and is narrowly tuned for excitation ...

Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

Computational fluid dynamics simulations of airflow through the nasal passages of rhinolophoid bats
Abstract The nasal passages of bats that emit their echolocation call through their nostrils have adapted for sound emission as well as standard respiratory and olfactory functions. Rhinolophids, hipposiderids and rhinonycterids all use a high duty cycle (HDC) echolocation strategy.

Exceptional preservation informs the paleobiology of tapinocephalid dinocephalians
Abstract The tapinocephalid dinocephalian Moschops is one of the most iconic taxa of the middle Permian, yet its paleobiology remains one of the least well‐known. Here, we address some aspects of paleoneurology and paleobiology of Moschops using CT scanning of four well preserved skulls from the upper Abrahamskraal Formation of South Africa. Two of the

Massive Esthesioneuroblastoma of middle turbinate
Esthesioneuroblatoma (ENB) is well known for its rarity, infact about 1000 cases are described in literature since its first detection. ENB presents a large variety of symptoms and rapid progression.
