Well-organized eating and grooming behaviors were elicited in cats by stimulation of a zone in the cerebellum that extended from the fastigial nucleus to the superior cerebellar peduncle. Behaviors appeared to result from the facilitation of specific sensorimotor mechanisms, rather than the induction of generalized "drive" states. The results emphasize the need for a broad view of cerebellar fu...

We applied a single-shot echo-planar axial diffusion tensor sequence with parallel imaging for tractography of the cervical cord. Placing a large region of interest on a reconstructed sagittal image, the cervical cord was depicted as a tract bundle showing color-encoded cephalocaudally. By setting one region of interest in the cerebral peduncle and another in the entire cord on source images, t...

Rhizophoramucronatavar.alokii (Rhizophoraceae), a new variety of Rhizophora from the Andaman and Nicobar Islands, India, is described and illustrated. The new variety is remarkable in having four stamens, laterally folded leaves, a short peduncle, thick leathery petals, and a four-sided ovary with a sessile style. A key for the species of Rhizophora of the Andaman and Nicobar Islands is also pr...

PURPOSE Silent magnetic resonance imaging (MRI) scans produce reduced acoustic noise and are considered more gentle for sedated children. The aim of this study was to compare the validity of T1- (T1W) and T2-weighted (T2W) silent sequences for myelination assessment in children with conventional spin-echo sequences. MATERIALS AND METHODS A total of 30 children (21 boys, 9 girls; age range: 1-...

Medullomyoblastoma is a variant of medulloblastoma with an aggressive course. It is typically seen in children less than 10 years of age and usually arises from the cerebellar vermis. Authors report an unusual case of medullomyoblastoma arising from the right middle cerebellar peduncle in an adult patient and pertinent literature is reviewed regarding this uncommon entity.
