Ultrasonography of neonatal cerebral arteries is common in routine clinical practice and largely proceeds on the assumption of trans-midline symmetry. The resolution of existing methodologies has not been extended to detect the existence of structurofunctional asymmetries]. In previously used Doppler techno...
The cerebral cortex is the part of the brain responsible for higher cognitive abilities. Learn more about its structure and functions at Kenhub!
1A). Cerebral (basilar) arteries and their first order branches from near-term baboon fetuses were visually identified as surface vessels on the inferior side of the fetal cerebellum. Under a microscope, up to 1 g of arteries was dissected out under a microscope from each donor and gently ...
Anterior circulationrefers to the common carotid and its distal ramifications, including the internal carotid, middle cerebral, andanterior cerebral arteries. Theposterior circulationrefers to the vertebral andbasilar arteriesand their branches, including theposterior cerebral artery. ...

On the other hand, acute hypoxia and hypercapnia cause an increase in cerebral blood flow (CBF) via dilations of cerebral arteries and arterioles27, counteracting the increase in blood pressure and blood supply. In addition, sleep related factors such as different sleep stages28,29,30, and ...
4or a blood clot that originates in a different place (embolus, sporadic),5whereas the global cerebral ischemic condition originates due to hypoperfusion or a drastic reduction of CBF in the overall brain caused by large-artery atherosclerosis, complete obstruction of the carotid arteries, cardiac...
Amyloid is deposited in the walls of arteries and capillaries as cerebral amyloid angiopathy (CAA) in the brains of older individuals and of those with Alzheimer disease (AD). CAA in AD reflects an age-related failure of elimination of amyloid-beta (Aβ)
Although the immune response-related pathways were among the 20 most enriched pathways of up-regulated genes in the BCAS group, the majority of these pathways were related to neuronal and synaptic functions. These results indicated that in the process of single-nuclei sequencing, the non-neuronal ...
The main components of the arteries are smooth muscle cells, which are considered the main regulators of vascular tone and blood flow distribution. The information currently available on the functioning of the cerebral arteries and their cell constituents is extremely scarce. Thus, the aim of this ...
