This study brings to light two additional MRI signs not previously reported: the closure of the interpeduncular
fossa and buckling of the tuber cinereum over the dorsum.
The distribution of SAH in the preoperative CT did not usually involve the interpeduncular
and prepontine cisterns [Figure 3]a], suggesting an intact Liliequist's membrane.
The finding of an increased number of nAChRs in the regions of the epithalamus (medial habenular area) and the interpeduncular
nucleus (IPN) seem to be particularly interesting in the context of a sleep disorder.
In the patients with aqueductal stenosis or obstruction, intraaqueductal CSF flow is reduced or fully absent, so endoscopic fenestration of the third ventricle floor provides an alternative quasi-physiological CSF flow pathway to the subarachnoid spaces through the interpeduncular
cistern and downwards, resulting in dispersed and minimized pressure gradient on midline brain structures, surrounding cerebral aqueduct .
The principal MRI findings of Joubert syndrome are deep interpeduncular
fossa together with a narrowing of the isthmus, thickening of the superior cerebellar peduncle, fourth ventricle deformity together with hypolplasia of the vermis, fastigumun rostral shift and sagittal vermian cleft originating from the incomplete union of the two halves of the vermis.
Circle of Willis (CW) is a polygonal anastomotic channel at the base of the brain which unites the internal carotid and vertebrobasilar system of arteries in the interpeduncular
They found that physical nicotine withdrawal symptoms are triggered by activation of GABAergic neurons (neurons that secrete GABA, the brain's predominant inhibitory neurotransmitter), in the interpeduncular
Studies in mice show that nicotine addiction can be traced to a single brain region called the interpeduncular
Researchers, who conducted studies in mice, found that nicotine addiction can be traced to a single brain region called the interpeduncular
nucleus, where neurons "fire up" when someone is gasping for a cigarette, News.com.au reported.
The molar tooth sign refers to the characteristic appearance on axial CT or MRI of enlarged and horizontally directed columnar structures on each side of the midline flanking a deep interpeduncular
Background: The circle of Willis, present in the interpeduncular
cistern at the base of the brain, is the major source of blood supply of the brain.
