Watershed Infarction: Flair axial MRIs: Note the linear area of infarction between the distributions of the middle cerebral artery (MCA) and anterior cerebral artery (ACA) on the left side of the ...

Researchers scanned the brains of people as they drank water. Brain areas involved in emotional decision-making lit up in the scanner when people drank in response to feeling thirsty, whereas ...

ACA = anterior cerebral artery, ICA = internal carotid artery. In this case, the embolus resulted in a deep watershed infarction involving the right basal ganglia and internal capsule. Although ...

The watershed distribution pattern, involving arterial boundary areas between the anterior and middle cerebral arteries, and/or between the middle and posterior cerebral arteries, was observed in ...

The effects on the brain are lower white matter volume and a decrease in the microstructural integrity in the watershed areas. These changes have the potential to lead to cognitive dysfunction.
