متن کاملVentriculus terminalis of the conus medullaris: MR imaging in four patients with congenital dilatation.
MR findings in four patients with MR evidence of congenital cystic dilatation of the ventriculus terminalis were reviewed retrospectively.

The dilated ventriculus terminalis appears on MR images as a small ovoid cavity with reg...
متن کاملThe organum vasculosum laminae terminalis in immune-to-brain febrigenic signaling: a reappraisal of lesion experiments.
The organum vasculosum laminae terminalis (OVLT) has been proposed to serve as the interface for blood-to-brain febrigenic signaling, because ablation of this structure affects the febrile response. However, lesioning the OVLT causes many "side effects" not fully accounted for in the fever literature. By placing OVLT-lesioned rats on intensive rehydration therapy, we attempted to prevent these ...
