Scientists can see everything going on in Gordon's brain as he learns and makes decisions - something that's not possible in a whole animal.
'The Holy Grail of neuroscience is to link activity in brain cells with the complex behaviour we see in animals,' explains Ben Whalley, brain scientist at the University of Reading. 'We hope that Gordon may help us do this; when he moves left or right we can see exactly what's going on between his neurons.'
