Above pons and further forward, rostrally towards nose, are cerebellar peduncles, inferior olive, quadrigeminal plate, nucleus accumbens, red nucleus, substantia nigra, tectum, and midbrain tegmentum {midbrain}|. All midbrain nuclei have ascending and descending axon tracts. Midbrain is for attention, controls aggressiveness, and predicts adjustments to visual perception that will result from movement, using signal {central kinetic factor} that codes displacement direction and speed.
