Brainstem mediates diazepam enhancement of palatability and feeding: microinjections into fourth ventricle versus lateral ventricle.
The hypothesis that benzodiazepine-induced hyperphagia is due to a specific enhancement of the palatability of foods has been supported by previous 'taste reactivity' studies of affective (hedonic and aversive) reactions to taste palatability. Diazepam and chlordiazepoxide enhance hedonic reactions of rats (rhythmic tongue protrusions, etc.) to sweet tastes in a receptor-specific fashion. A rol...
متن کاملTrapped Fourth Ventricle in Recurrent Acoustic Schwannoma - A Rarity Quarto ventrículo isolado com schwannoma acústico recorrente – uma raridade
Fourth ventricular dilatation is usually seen along with tri-ventriculomegaly in patients with communicating hydrocephalus. Isolated fourth ventricular dilatation is uncommon, especially as a sequelae following infective or post hemorrhagic communicating hydrocephalus.1 Ventricular shunting often causes a collapse in the system, and postinflammatory scarring in the aqueduct causes adhesions bet...
متن کاملWegener granuloma in the fourth ventricle.
We report the case of a 57-year-old man with a known history of antineutrophil cytoplasmic antibody-positive Wegener granulomatosis with initial involvement of the upper and lower respiratory tract. MR imaging of the brain was performed because of new onset CNS symptoms (nausea, altered mental status). The images revealed a mass in the fourth ventricle. The mass diminished in size after systemi...
متن کاملHemangioblastoma of the Fourth Ventricle : Case Report
mal cells and a subependymal plate composed of glial cells. Accordingly, these layers give rise to ependymomas, subependymomas, and subependymal giant cell astrocytomas (1). Hemangioblastomas are benign vascular tumors with an uncertain origin. They account for 12% of all intracranial tumors, and are a component of the von Hippel-Lindau syndrome in 30% of cases (2, 3). Hemangioblastomas usually...
متن کاملClinical anatomy of the fourth ventricle foramina
Introduction The three foramina of the fourth ventricle of the human brain were first described during the 19th century. The primary purpose of this article was to review the anatomy of the foramina of the human fourth ventricle, as well as the main clinical conditions related to pathology of these neurosurgically important structures. The existing literature regarding the gross and neurosurgic...
