## **Core Concept**
Pseudolaminar necrosis, also known as laminar necrosis, is a type of brain injury characterized by the death of neurons in the cerebral cortex, specifically affecting the layers of the cortex. This condition often results from global cerebral ischemia.

## **Why the Correct Answer is Right**
The correct answer, **C. Global cerebral ischemia**, is associated with pseudolaminar necrosis because this condition leads to a lack of blood flow to the brain, resulting in neuronal death that often respects the laminar architecture of the cerebral cortex. This type of injury can occur due to cardiac arrest, severe hypotension, or other causes of reduced cerebral perfusion.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is blank and cannot be evaluated.
- **Option B:** This option is blank and cannot be evaluated.
- **Option D:** This option is blank and cannot be evaluated.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that pseudolaminar necrosis is often seen in the context of global cerebral ischemia, such as after cardiac arrest. This condition can lead to selective neuronal vulnerability, particularly affecting the cerebral cortex in a laminar pattern.

## **Correct Answer:** . Global cerebral ischemia
