Perhaps it would be more accurate to say that the grasshoppers turning
response to a particular stimulus isn't reliant on prior internal state, but
solely dependent on feedforward processing.

I'm not entirely certain if that's true, though. Anyone know if there's any
thing like habitutation in this system, or any sort of modulatory effects?
