The stimuli then pass through the medial lemniscus to the thalamus and reach the primary sensory cortex generating the N20/P22 potential.
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 respectively).
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.
The evoked potential is generated in the cochlea, goes through the cochlear nerve, through the cochlear nucleus, superior olivary complex, lateral lemniscus, to the inferior colliculus in the midbrain, on to the medial geniculate body, and finally to the auditory cortex.
Finally, peak IV in monkeys (which is analogous to peak V in humans) was determined to originate from the contralateral lateral lemniscus. In our study, the latencies and amplitudes of peaks I, II and IV were accurately calculated.
This system is called the dorsal column medial lemniscus. It is worth noting that Ia and Ib neuronal afferents from lower extremities terminate on the cerebellum too (1,29).
mesencephalicus lateralis, pars dorsalis [18] as well as from the nuclei of the lateral lemniscus. The surroundings of these two nuclei form an additional subdivision of the auditory thalamus, called the ovoidal shell.
A recent magnetic resonance imaging (MRI) study reported similar findings with respect to degeneration and reorganization of the sensorimotor tracts (pyramidal tract and medial lemniscus) after hemispherectomy [6].
