Question: How would you collect the brain cells?

With the technique called cell culture, it is very possible.
I dissect a mammalian brain and take out the desired portion of the brain. For experimental purpose, Wistar rat is used. I mainly use the part of the brain called the cortex which processes information in the brain. I digest the cortex with enzymes and this changes it to millions of cells in a small test tube. I add little drops of the specimen on many coverslips and put them in the incubator for 14 days while adding drugs that can either make brain cells (Neurons) multiply rapidly or have a retardation in growth.
