“…Here, the signal recorded at the Cz site was analyzed since it exhibited the largest SNR and it has been reported in previous EEG monkey studies 31 . Furthermore, artifacts due to the postauricular muscle reflex are diminished by using the vertex-inon derivation 78 .…”

The extraction and encoding of acoustical temporal regularities are fundamental for human cognitive auditory abilities such as speech or beat entrainment. Because the comparison of the neural sensitivity to temporal regularities between human and animals is fundamental to relate non-invasive measures of auditory processing to their neuronal basis, here we compared the neural representation of auditory periodicities between human and non-human primates by measuring scalp-recorded frequency-following response (FFR). We found that rhesus monkeys can resolve the spectrotemporal structure of periodic stimuli to a similar extent as humans by exhibiting a homologous FFR potential to the speech syllable /da/. The FFR in both species is robust and phase-locked to the fundamental frequency of the sound, reflecting an effective neural processing of the fast-periodic information of subsyllabic cues. Our results thus reveal a conserved neural ability to track acoustical regularities within the primate order. These findings open the possibility to study the neurophysiology of complex sound temporal processing in the macaque subcortical and cortical areas, as well as the associated experience-dependent plasticity across the auditory pathway in behaving monkeys.

“…Waves I and II emanate from the auditory nerve and waves III and IV are believed to be generated in the cochlear nucleus and the superior olivary complex, respectively (13,14). Wave V is believed to reflect activity at the levels of the lateral lemniscus and the inferior colliculus and waves VI and VII are suggested to have thalamic (the medial geniculate body) origin (15). By examining the waveforms, peak latencies in milliseconds and peak amplitudes in microvolt of individual waves various audiological and neurological abnormalities can be detected (13,14,16,17) with the disadvantage, however, that the amplitudes of the ABR waves have been difficult to quantify and characterize due to complex waveforms and high inter- and intra-individual variability (18).…”

“…The experience described in the numerous articles demonstrates the effectiveness of CoMEPs use to achieve on-line monitoring of control to functional integrity cranial motors fibers [18,[25][26][27][28][29][30], if followed at the all rules, the registration can be without interruption the surgeon's work [16,27]. In recent years, the use of different types of reflexes became frequently [27,[31][32][33][34], oppositely BAEPs technique which was basic in the 90s for brainstem monitoring [35,36], but in our time gives only 20% of the brainstem area [10,26].…”

Surgery of intrinsic brainstem lesions is extremely dangerous, consequently the knowledge of anatomy and safe entry zones is extremely important. The technological progress was achieved with the widespread clinical use of intraoperative neurophysiological monitoring (IONM) which has proven to further improve the safety of operating on intrinsic brainstem lesions. The relevance of the study is conditioned by the fact that the tumor alters the normal anatomy and distorts the location of well-known landmarks and structures. In this regard, this paper is directed at identification of the placement of conductive pathways in the thickness of the brain stem and directly in the depth of the lesion (in the tumor or cavern), respectively to the surgical manipulations aimed at injury prevention. The results were achieved by a retrospective review of medical reports. The paper represents the results of surgical treatment of 42 patients with brainstem lesions, reviews the localization of the lesion and neurological status of patients, describes available methods of intraoperative monitoring (IOM) and on-line techniques for the brainstem surgery. The materials of the paper are of practical significance for the development of brainstem surgery with IONM modifications for wider and more comfortable use by neurosurgeons.
