You wait all year for neuroscience themed graffiti and then two come along in a week. This was found on Carrera 31 in Medellín yesterday morning.
It turns out that over the years I’ve managed to collect a fair amount of brain-themed graffiti for Mind Hacks, which you can browse at your pleasure here.
And with that, I leave the booming, buzzing confusion of Medellín and head back to the sustained attention of London.
Mind Hacks 
street art + psychology. A new interest is born.
