Amazing stuff!
"Yet, as the developers of autonomous vehicles have learned, identifying the trajectory of movement through space is one of the most challenging computational problems. ... The findings shed new light on flexibility in complex neural circuits: Despite their set anatomical structure, they are highly dynamic. ... But antagonistic center-surround was not thought to take part in identifying the direction of movement. ... discovered ... that a certain type of light stimulus could get direction-selective retinal ganglion cells to reverse the direction of movement they responded to by 180 degrees. This was unexpected: The cells changed their direction selectivity despite the fact that the selectivity to motion is thought to be “hard-wired” via asymmetric connections from other neurons in their network."
