Artery of Percheron (AOP) is a normal, but uncommon vascular variant of the paramedian branches of the PCA in which a single dominant TPA trunk arises from one P1 segment, bifurcates, and provides bilateral supply to the paramedian thalami and the rostral midbrain
Although FGF8 and SHH determine DA phenotype, the regional identity of the DA neurons (forebrain or midbrain
phenotypes) can be specified under a chemical-defined media composition.
existed in her midbrain
[Figure 1]e and [Figure 1]f, which was mentioned in the exclusion criteria (one of the mandatory exclusion terms in the NINDS-SPSP criteria of the diagnosis of PSP).
infarcts may result after occlusion of the artery of Percheron and they are usually limited to periaqueductal gray matter (6) and affect the oculomotor and reticular nuclei.
(2) The locations of rarer large brain capillary telangiectasias have been reported in the pons, basal ganglia, midbrain
, temporal lobes, and parafalcine frontal lobes.
Axial T2-weighted MRI of the brain showed the characteristic 'face of the giant panda' sign in the midbrain

The optic lobes are bilaterally symmetrical, and in front of the midbrain
, the head of caudate nucleus is visible (Fig.
Deploying MRI scans, the team then focused on the relatively rigid midbrain
, which includes the brain stem and is situated in the center of the head, under the cerebral cortex.
For this study, Tschida and her colleagues focused on a part of the midbrain
called the periaqueductal gray, or PAG for short, because they knew from previous work by others that it would be a key player in the vocalization circuit, she said.
(1,2) Thalamoperforators arise off the posterior cerebral arteries to supply the paramedian region of the thalamus bilaterally and extend to supply a portion of the rostral midbrain
. Typically, each thalamic hemisphere has its own blood supply via these thalamoperforators.
Jeet is a practitioner of midbrain
activation, a technique which helps people visualise objects without seeing them and is also known as super-sensory development.
This was compared with 93, 90, and 92 percent for midbrain
ultrasound, and 62, 89, and 73 percent for smell detection.
It already was known that short sounds are discriminated from longer sounds by individual brain cells in the inferior colliculus, the auditory part of the midbrain
