WILLIAM AND MARY (ROALD DAHL) AND THE COVERINGS OF BRAIN

And now, as I say, I'd take a small oscillating saw and carefully remove your complete calvarium--the whole vault of the skull. This would expose the top half of the brain, or rather the outer covering in which it is wrapped. You may or may not know that there are three separate coverings around the brain itself the outer one called the dura mater or dura, the middle one called the arachnoid, and the inner one called the pia mater or pia. Most laymen seem to have the idea that the brain is a naked thing floating around in fluid in your head. But it isn't. It's wrapped up neatly in these three strong coverings, and the cerebrospinal fluid actually flows within the little gap between the two coverings, known as the subarachnoid space. As I told you before, this fluid is manufactured by the brain and it drains off into the venous system by osmosis


The coverings of the brain are very well explained. The tale is about a dyng man who is offered to keep his brain alive in a basin, with an eye as the only way to interact with the enviroment. The man accepted the offer only because he would be able to read.

At the end of the short story, the wife wants to take her husband´s brain home because she realizes that she likes him better now and it/he gives her no trouble.
Last month, in Yale´s University a group of scientists has brought brains of pigs back to life. This fact is linked with another of Dahl’s tales – ‘Pigs’, a wonderful allegation in favour of veganism, just like the film The Executioner, by Berlanga, is the best allegation against death penalty
