Neurological lesions above the red nucleus (intercollicular line in the midbrain) tend to cause decortication and lesions below, decerebration.

There are at least 3 tracts and 1 nucleus that have the name "arcuate" in them.
As for "Lemniscus," you have 2 of them.

Arcuate fasciculus: connects Broca's with Wernicke's area.
Internal Arcuate tract: connects the dorsal column nuclei with the thalamus.
Anterior/posterior External Arcuate tract: connects the dorsal column nuclei with the pons & the cerebellum.
Arcuate nucleus: I don't even know where that is

Medial Lemniscus: the continuation of the internal arcuate tract outside the medulla is named the medial lemniscus. It connects the dorsal column nuclei with the thalamus.
Lateral Lemniscus: connects the auditory nuclei (superior olivary & cochlear) with the inferior colliculi.
