Steve Caplin explains that the latest research shows that humans have not just one brain but two. Scientists at Stanford have created a human-mouse hybrid to help study the causes of conditions like…
Simon RoseHostThis is according to Stanford University in the United States, who have discovered, or they reckon, that the brain is actually two separate organs.
So
they've got the forebrain and the midbrain, which does all the thinking and sensing.
They all said we've got left and right hand side, so which bits are the left and the right hand bits in?
And the third group is the ectoderm, which then turns into the skin and the nervous system.
And scientists apparently have been puzzled about this for decades because they now think that part of the brain grows in the first two groups and part of the brain actually grows in the third group, in the ectoderm.
Does this mean we need to think differently? Well, I was going to say, yes, what can we do with it? Except go around boasting, I've got two brains.
You could always try doing that, although I think the ya-ya-ya-ya-ya might rather spoil your head.
Yes, one of them's not quite as bright as the other one, and I'm using that at the moment.
Well, whenever one gets anything wrong, you say, I'm terribly sorry, I'm using the wrong brain.
perfect excuse now for anything that goes wrong, of which there have been many things recently.
And the Stanford University have not just been working out that we've got two brains, but they've also been building the first human-mouse hybrid.
