Thank you for your post. When cells in the brain are damaged and die such as in stroke or surgery, there is no repair or scar formation. Instead, the brain tissue usually undergo liquefactive necrosis forming a rim of gliosis around the damaged area. This is because there are usually no collagen or fibroblasts in the brain which are responsible for scar formation elsewhere. If there is a recent brain surgery, talk to your attending physician and discuss post-op outlook to ease any worry. Take care and do keep us posted.
