How fast is the speed of thought?

Your mortal enemy has captured you and hooked you up to a bizarre experiment. He's extended your nervous system with one very long neuron to a target about 70 meters away. At some point, he's going to fire an arrow. If you can then think a thought to the target before the arrow hits it, he'll let you go. So who wins that race? Seena Mathew examines the speed of thought. [Directed by Andrew Foerster, narrated by Bethany Cutmore-Scott].
