all alone on a sort of tray, was alive. The brain was functioning. They proved it by several tests. For example, when food was smeared on the dog’s lips, the tongue would come out and lick it away; and the eyes would follow a person moving across the room.
‘It seemed reasonable to conclude from this that the head and the brain did not need to be attached to the rest of the body in order to remain alive – provided, of course, that a supply of properly oxygenated blood could be maintained.
‘Now then. My own thought, which grew out of seeing this film, was to remove the brain from the skull of a human and keep it alive and functioning as an independent unit for an unlimited period after he is dead. Your brain, for example, after you are dead.’
‘I don’t like that,’ I said.
‘Don’t interrupt, William. Let me finish. So far as I can tell from subsequent experiments, the brain is a peculiarly self-supporting object. It manufactures its own cerebrospinal fluid. The magic processes of thought and memory which go on inside it are manifestly not impaired by the absence of limbs or trunk or even of skull, provided, as I say, that you keep pumping in the right kind of oxygenated blood under the proper conditions.
‘My dear William, just think for a moment of your own brain. It is in perfect shape. It is crammed full of a lifetime of learning. It has taken you years of work to make it what it is. It is just beginning to give out some first-rate original ideas. Yet soon it is going to have to die along with the rest of your body simply because your silly little pancreas is lousy with cancer.’
‘No thank you,’ I said to him. ‘You can stop there. It’s a repulsive idea, and even if you could do it, which I doubt, it would be quite pointless. What possible use is there in keeping my brain alive if I couldn’t talk or see or hear or feel? Personally, I can think of nothing more unpleasant.’
‘I believe that you would be able to communicate with us,’ Landy said. ‘And we might even succeed in giving you a certain amount of vision. But let’s take this slowly. I’ll come to all that later on. The fact remains that you’re going to die fairly soon whatever happens; and my plans would not involve touching you at all until after you are dead. Come now, William. No true philosopher could object to lending his dead body to the cause of science.’
‘That’s not putting it quite straight,’ I answered. ‘It seems to me there’d be some doubt as to whether I were dead or alive by the time you’d finished with me.’
‘Well,’ he said, smiling a little, ‘I suppose you’re right about that. But I don’t think you ought to turn me down quite so quickly, before you know a bit more about it.’
‘I said I don’t want to hear it.’
‘Have a cigarette,’ he said, holding out his case.
‘I don’t smoke, you know that.’
He took one himself and lit it with a tiny silver lighter that was no bigger than a shilling piece. ‘A present from the people who make my instruments,’ he said. ‘Ingenious, isn’t it?’
I examined the lighter, then handed it back.
‘May I go on?’ he asked.
‘I’d rather you didn’t.’
‘Just lie still and listen. I think you’ll find it quite interesting.’
There were some blue grapes on a plate beside my bed. I put the plate on my chest and began eating the grapes.
‘At the very moment of death,’ Landy said, ‘I should have to be standing by so that I could step in immediately and try to keep your brain alive.’
‘You mean leaving it in the head?’
‘To start with, yes. I’d have to.’
‘And where would you put it after that?’
‘If you want to know, in a sort of basin.’
‘Are you really serious about this?’
‘Certainly I’m serious.’
‘All right. Go on.’
‘I suppose you know that when the heart stops and the brain is deprived of fresh blood and oxygen, its tissues die very rapidly. Anything from four to six minutes and the whole thing’s dead. Even after three minutes you may get a certain amount of damage. So I should have to work rapidly to prevent this from happening. But with the help of the machine, it should all be quite simple.’
‘What machine?’
‘The artificial heart. We’ve got a nice adaptation here of the one originally devised by Alexis Carrel and Lindbergh. It oxygenates the blood, keeps it at the right temperature, pumps it in at the right pressure, and does a number of other little necessary things. It’s really not at all complicated.’
