BACKGROUND White matter (WM) and grey matter (GM) brain damage in multiple sclerosis (MS) is widespread, but the extent of cerebellar involvement and impact on disability needs to be clarified. OBJECTIVE This study aimed to assess cerebellar WM and GM atrophy and the degree of fibre coherence in the main cerebellar connections, and their contribution to disability in relapsing-remitting MS (R...

INTRODUCTION Many neurologic and psychiatric disorders are thought to be due to, or result in, developmental errors in neuronal cerebellar connectivity. In this connectivity analysis, we studied the developmental time-course of cerebellar peduncle pathways in pediatric and young adult subjects. METHODS A cohort of 80 subjects, newborns to young adults, was studied on a 3T MR system with 30 di...

Olyra saginata, new species, is described from the Kaladan [=Kolodyne] River system in Mizoram, northeast India. It differs from congeners in having the following unique combination of characters: interorbital distance 27.9-35.9% HL; 54-66 lateral-line pores; body depth at anus 10.5-12.0% SL; length of adipose-fin base 17.3-22.4% SL; adipose fin separate from upper principal caudal-fin rays; po...

Paired imaging studies consisting of computed tomography (CT) and magnetic resonance imaging (MRI) were performed in eight dogs to evaluate subjectively whether MRI is superior to CT in detecting intracalvarial changes associated with canine nasal neoplasia. Imaging in four anatomical regions (caudal ethmoturbinates, cribriform plate, frontal sinuses, and the olfactory peduncle of the frontal l...
