He visits the multi-million dollar centre which has been set up since HM died to map his unique brain down to the level of an individual neuron.
And there was these people who had their brains cut in half! Surgeons cut the Corpus Callosum which links the 2 hemispheres of the brains, and the patients carried on living normal lives...... almost.
We know the right side of the brain controls the left hand side of the body, and vice versa.
Well, get this. People who have had their Corpus Callosum severed, could identify a number placed in their left hand by holding up the relevant amount of fingers, but they couldn't say what number it was.
So a test showed someone feeling the number seven (that she couldn't see) and then held up seven fingers (five and then two, for you funny fuckers.

Also, the left hand done a simple puzzle, but the right hand couldn't do it.
. And then when they come back, they can
