Other commonly reported adverse effects related to stimulation include dysarthria, diplopia, and paresthesia (reflecting stimulus spread to the internal capsule, ocular motor nerve complex, and medial lemniscus
Assignment of wave I to auditory nerve activity is universally accepted and origin of wave V appears to be in the nucleus of the lateral lemniscus
in humans (Moller and Janetta, 1984).
However microelectrode stimuli applied directly to cortical areas such as the medial lemniscus
(LM) do not produce such early time markers.
Wave II originates from cochlear nucleus, Wave III from superior olivary nucleus, Wave IV from lateral lemniscus
, and Wave V from inferior colliculi in the midbrain.
Finally, peak IV in monkeys (which is analogous to peak V in humans) was determined to originate from the contralateral lateral lemniscus
This system is called the dorsal column medial lemniscus
