WebPontine lacunar infarcts may also damage the corticospinal tracts. The blood supply of the medulla is derived from the two vertebral arteries. The midline anterior spinal artery, formed from the fusion of medial branches from each vertebral, supplies part of the central medulla (as well as much of the upper cervical cord). WebVascular dementia is a common type of dementia caused by reduced blood flow to the brain. It's estimated to affect around 150,000 people in the UK.

WebThe blood supply of the brainstem and cerebellum is derived entirely from branches of the vertebrobasilar circulation. The vertebral arteries enter the cranium via the foramen magnum and course superiorly along the ventrolateral surface of medulla. They then unite at the caudal border of the pons to form the midline basilar artery. WebIn animal studies, lesions of the pontine tegmentum greatly reduce or even eliminate REM sleep. Injection of a cholinergic agonist (e.g. carbachol), into the pontine tegmentum produces a state of REM sleep in cats. PET studies seem to indicate that there is a correlation between blood flow in the pontine tegmentum and REM sleep
