The cerebrum is the brain's largest region, responsible for functions like thought, movement, and sensory processing. When an Agranular (AG) stain is applied to cerebral tissue, it highlights the brain’s cellular structure, helping researchers examine the details of neurons and supporting cells. This technique makes it easier to study the organization of the cerebral cortex, revealing the different layers and the density of cells within them. AG staining is especially useful for identifying subtle changes or damage in brain tissue, which is important for understanding neurological conditions or diseases like Parkinson’s or Alzheimer’s.

The cerebrum is the largest part of the brain and is responsible for many important functions like thinking, memory, emotions, and movement. It’s divided into two halves, called hemispheres, and has many folds and grooves that help increase its surface area so it can process more information. This part of the brain is what makes us aware of the world around us and helps us make decisions every day.
