Exceptional preservation informs the paleobiology of tapinocephalid dinocephalians

open access: yesThe Anatomical Record, EarlyView.
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

Sensory and motor mechanisms of oculomotor inhibition of return

open access: yes, 2012
We propose two explicit mechanisms contributing to oculomotor inhibition of return (IOR): sensory and motor. Sensory mechanism: repeated visual stimulation results in a reduction in visual input to the superior colliculus (SC); consequently, saccades to ...

Location- and feature-based selection histories make independent, qualitatively distinct contributions to urgent visuomotor performance

open access: yeseLife
Attention mechanisms guide visuomotor behavior by weighing physical salience and internal goals to prioritize stimuli as choices for action. Although less well studied, selection history, which reflects multiple facets of experience with recent events ...

The role of cerebellar circuitry alterations in the pathophysiology of autism spectrum disorders

open access: yesFrontiers in Neuroscience, 2015
The cerebellum has been repeatedly implicated in gene expression, rodent model and post-mortem studies of autism spectrum disorder (ASD). How cellular and molecular anomalies of the cerebellum relate to clinical manifestations of ASD remains unclear ...

Production of 3D printed biomodels of the canine brain for veterinary neuroanatomy teaching

open access: yesAnatomical Sciences Education, EarlyView.
Abstract Teaching neuroanatomy presents multiple challenges to both students and teachers, as it is a subject with highly dense content that commonly causes the development of aversion by students, a phenomenon referred to as “neurophobia,” which has been documented in human and veterinary medicine students.

Histopathological changes in oculomotor nerve and ciliary ganglion in aneurysmatic compression injures of oculomotor nerve

open access: yes, 2005
Bilateral common carotid artery ligation (BCCAL) increases vertebrobasilar blood flow and leads to increased luminal pressure, luminal enlargement, wall thinning, convolutions and sometimes aneurysm formation in posterior circulation arteries, especially

Reticular Formation Connections Underlying Horizontal Gaze: The Central Mesencephalic Reticular Formation (cMRF) as a Conduit for the Collicular Saccade Signal

open access: yesFrontiers in Neuroanatomy, 2017
The central mesencephalic reticular formation (cMRF) occupies much of the core of the midbrain tegmentum. Physiological studies indicate that it is involved in controlling gaze changes, particularly horizontal saccades.

Immersive virtual reality as a teaching tool in neuroanatomy: A scoping review

open access: yesAnatomical Sciences Education, EarlyView.
Abstract Basic core courses in various undergraduate programs, such as neuroanatomy, pose a challenge for students due to the large volume and complexity of the content. In this context, educational technologies such as immersive virtual reality (IVR), which allow students to actively interact with learning materials, offer a complementary pedagogical ...

Unilateral Oculomotor Nerve Palsy Secondary to Internal Carotid Artery Aneurysm Without Pupil involvement: A Case Report

open access: yes, 2023
Acquired oculomotor palsies (OMP) can result from numerous factors. The most common causes are presumed microvascular, trauma, compressive neoplasm, postneurosurgery and compression from aneurysm.1,2 ONP caused by internal carotid artery (ICA) aneurysm ...
