Brain cells vs neurons.

I'm going to die if I continue reading nervous system. I studied the same chapter for 3 days continuously. Day and night. Before that, I did my physiology assignment which is related to nerves as well. Oh gosh. I regret. Shouldn't choose Parkinson's topic. Deal with nerves and neurotransmitters for 2 months isnt something fun. Imagination consumes a lot of energy and a large amount of my brain cells die off because of that.. Sigh.. No matter how, i still gonna clarify with nervous system chapter before thursday's MCQ test.. SAY NO TO NERVOUS SYSTEM FOR 12 hours.. My brain needs some other interesting topic..
