After few brained speedboost predators I made I wondered if there was a way to obtain the same behaviour but without a Neurocyte.
I thought it was impossible but playing with stereocyte position I tried to put them in a diagonal position respect to the front.
This is the result
there is a crossbow predator in youtube that also uses the speed boost without a neurocyte.
I know, but it has 3 stereocytes and works with separated vertical and horizontal components of sense, so the lateral flagellocytes can't boost.
With 45 degrees stereocytes you only need two stereo and two flagellos using only 6 cells, or 7 if the devorocyte splits.
Neurocyte is necessary if you want a predator with only two flagellos
This is the version with neurocyte
