Monitoring this display and observing the activity of the brain cells tiny moto is able to determine which of the neurons were involved in identifying the electric shock what's more he's been able to influence the neurons behavior. but it's even more striking is that we can manipulate this single neuron in the freedom it behaving flies freely moving. we can block or activate. this very small subset of neurons. in short term to motor has been able to hack into the brain of a fruit fly we can recreate the activity of neurons that have been exposed to electric shock without actually doing any dam...
