Characterization of cardiac- and respiratory-driven cerebrospinal fluid motion based on asynchronous phase-contrast magnetic resonance imaging in volunteers

Fluids and Barriers of the CNS, 2017
Background A classification of cardiac- and respiratory-driven components of cerebrospinal fluid (CSF) motion has been demonstrated using echo planar imaging and time-spatial labeling inversion pulse techniques of magnetic resonance imaging (MRI ...

Virtual brain endocasts of the palaeanodont Metacheiromys marshi and the neurosensory evolution of early Pholidotamorpha

Journal of Anatomy, EarlyView.
We describe the endocranial anatomy of Metacheiromys marshi. Decrease in olfaction and eye movement control occurred through time in Pholidotamorpha and is likely linked to fossorial adaptations. The development of the orbital gyrus might be related to the evolution of myrmecophagy and the emergence of a protrusile tongue in early Pholidotamorpha ...

The variability of giraffe skull morphology

Journal of Anatomy, EarlyView.
What does giraffe skull shape tell us about their development and evolution? Abstract Giraffe (Giraffa spp.) are among the most unique and charismatic extant animals, largely due to their distinct morphology. The evolutionary and developmental origin of ossicones is a key factor in giraffid biology, yet other features building their characteristic head

3D Analysis of Mandibular and Glenoid Fossa Responses to Bone‐Anchored Maxillary Protraction in Patients With UCLP

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Introduction Bone‐anchored maxillary protraction (BAMP) has been increasingly used to correct midface deficiency and Class III malocclusion in patients with unilateral cleft lip and palate (UCLP). However, its three‐dimensional (3D) effects on the mandible remain insufficiently explored.

Suitability of foramen magnum measurements in sex determination and their clinical significance

, 2018
Background: The foramen magnum provides a transition between fossa cranii posterior and canalis vertebralis. Medulla oblongata, arteria vertebralis and nervus accessorius spinal part pass through the foramen magnum.
