What is photothrombosis?
Photothrombosis is a technique used to induce localized ischemic damage in the brain using light-sensitive dyes.
How is the procedure performed?
The procedure involves exposing the skull, injecting a dye, and then activating it with light to induce thrombosis.
What are the applications of this technique?
It is used to study brain plasticity and cellular responses in transgenic mice.
Is photothrombosis invasive?
It is considered minimally invasive as it requires only a small incision to expose the skull.
What dye is used in photothrombosis?
Rose bengal is the light-sensitive dye commonly used in this technique.
How long is the light exposure during the procedure?
The target cortical area is exposed to light for 15 minutes.
