Various murine models of middle cerebral artery occlusion (MCAO) are widely used in experimental brain research. Here, we demonstrate the model of transcranial permanent distal MCAO which produces consistent cortical infarction of a size corresponding to damage imposed by the majority of human ischemic strokes.

Inducing Ischemic Stroke via Middle Cerebral Artery Occlusion Using a Thread Bolt

This video demonstrates the process of inducing ischemic stroke in a rat model by occluding the middle cerebral artery (MCA) using a thread bolt. The procedure involves ligating the carotid arteries, inserting a thread bolt into the external carotid artery, and blocking blood flow from the MCA to the brain, leading to neuronal death and mimicking an ischemic stroke.

Cerebral perfusion monitoring has been demonstrated to improve accuracy in ischemic stroke models. Technical difficulties often limit the use of this essential tool for cerebrovascular research. In this video, an optimized system is shown to obtain a single or multi-site hemodynamic monitoring during intraluminal middle cerebral artery occlusion in rats.

In order to understand the pathophysiology of stroke, it is important to use reliable models. This paper will describe one of the most frequently used stroke models in mice, termed the middle cerebral artery occlusion (MCAo) model (also termed the intraluminal filament or suture model) with reperfusion.
FAQs
Behavioral effects depend strongly on which supplied regions are injured and how extensive the damage is. Injury affecting language-related areas may produce aphasia, whereas damage involving attention-related systems can contribute to neglect or impaired attention. Lesion severity also helps explain why patients show different combinations of behavioral changes.
Ischemic and hemorrhagic injuries can affect behavior through different immediate processes. Ischemia deprives neurons of oxygen after blood flow falls, while hemorrhage adds bleeding from a ruptured vessel to the local injury. This distinction matters when interpreting behavioral findings because the same vascular territory can produce varied language, attention, emotional, or decision-making difficulties.
Variation reflects differences in lesion location and severity. One patient may primarily experience aphasia, while another may show neglect, impaired attention, emotional changes, or difficulties with decision-making and social behavior. These patterns are not interchangeable, so identifying the particular combination provides clues about which behavioral functions were most affected.
Language, attention, emotion, decision-making, and social behavior should not be treated as a single outcome. A patient may show aphasia alongside different problems in attention or behavior, depending on the injured regions. Considering these domains separately gives a more precise account of how the vascular injury affects everyday functioning.
Neurological assessment should consider more than motor or sensory impairment. Clinicians can examine language, attention, neglect, emotional changes, decision-making, and social behavior because these domains may be affected in different combinations. Mapping the observed difficulties helps characterize the patient's functional needs and supports individualized recovery planning.
Behavioral findings can guide rehabilitation by identifying which functions require attention during recovery. Aphasia may signal language-related limitations, while neglect or impaired attention may indicate different challenges. Emotional, decision-making, and social changes also matter because recovery planning should reflect the patient's broader behavioral profile rather than a single symptom.
Middle cerebral artery stroke provides a clinical context for linking damaged brain regions with behavioral functions. Researchers can compare lesion locations with changes in language, attention, emotion, decision-making, and social behavior. These observations help clarify how vascular injury disrupts behavior while also informing neurological assessment and rehabilitation planning.
