“…In the present study, we demonstrated modulation of VEP components C1 and N1 following HFS. These findings add to previous studies demonstrating that high-frequency (Teyler et al, 2005;Spriggs et al, 2017;Rygvold et al, 2020) and prolonged (Normann et al, 2007;Valstad et al, 2020) sensory stimulation modulate several VEP component amplitudes. This modulation effect has been repeatedly demonstrated for components C1, P1, N1b, and N1, of which modulation of the N1/N1b complex is the most consistent finding (Teyler et al, 2005;Normann et al, 2007;Elvsåshagen et al, 2012;Spriggs et al, 2017;Zak et al, 2018;Valstad et al, 2020).…”

“…Due to methodological limitations, the transition to human models explaining LTP have proven difficult. However, initiated by Teyler et al (2005), non-invasive EEG-derived methods have been developed to study LTP-like phenomena in humans, targeting changes in sensory evoked potential amplitudes following high-frequency sensory stimulation (e.g., Teyler et al, 2005;Spriggs et al, 2017;Rygvold et al, 2020) or prolonged sensory stimulation (e.g., Normann et al, 2007;Valstad et al, 2020). The experimental procedure involving the modulation of sensory evoked potentials which is regarded as a valid assay of LTP-like plasticity phenomena, is commonly referred to as the stimulus-selective response modulation (SRM) paradigm (Rygvold et al, 2020).…”

ObjectiveStimulus-selective response modulation (SRM) of sensory evoked potentials represents a well-established non-invasive index of long-term potentiation-like (LTP-like) synaptic plasticity in the human sensory cortices. Although our understanding of the mechanisms underlying stimulus-SRM has increased over the past two decades, it remains unclear how this form of LTP-like synaptic plasticity is related to other basic learning mechanisms, such as perceptual learning. The aim of the current study was twofold; firstly, we aimed to corroborate former stimulus-SRM studies, demonstrating modulation of visual evoked potential (VEP) components following high-frequency visual stimulation. Secondly, we aimed to investigate the association between the magnitudes of LTP-like plasticity and visual perceptual learning (VPL).Methods42 healthy adults participated in the study. EEG data was recorded during a standard high-frequency stimulus-SRM paradigm. Amplitude values were measured from the peaks of visual components C1, P1, and N1. Embedded in the same experimental session, the VPL task required the participants to discriminate between a masked checkerboard pattern and a visual “noise” stimulus before, during and after the stimulus-SRM probes.ResultsWe demonstrated significant amplitude modulations of VEPs components C1 and N1 from baseline to both post-stimulation probes. In the VPL task, we observed a significant change in the average threshold levels from the first to the second round. No significant association between the magnitudes of LTP-like plasticity and performance on the VPL task was evident.ConclusionTo the extent of our knowledge, this study is the first to examine the relationship between the visual stimulus-RM phenomenon and VPL in humans. In accordance with previous studies, we demonstrated robust amplitude modulations of the C1 and N1 components of the VEP waveform. However, we did not observe any significant correlations between modulation magnitude of VEP components and VPL task performance, suggesting that these phenomena rely on separate learning mechanisms implemented by different neural mechanisms.

“…Additionally, cetaceans could compensate their lack of cortical specialization by an increase in cortical surface (Morgane et al 1990), and thereby explaining the myeloarchitectonic increase of L6, known to be the cortico-cortical connection site. Wiring strategies in developing vision and hearing follow different routes and targets (Rygvold et al 2021;Sitko and Goodrich 2021) and may also rely on specific variation in the cortical column based on the presence and distribution of immature neurons in L2 and potential plasticity (La Rosa et al 2020).…”

The primary visual cortex of Cetartiodactyls: organization, cytoarchitectonics and comparison with perissodactyls and primates

et al. 2021

Cetartiodactyls include terrestrial and marine species, all generally endowed with a comparatively lateral position of their eyes and a relatively limited binocular field of vision. To this day, our understanding of the visual system in mammals beyond the few studied animal models remains limited. In the present study, we examined the primary visual cortex of Cetartiodactyls that live on land (sheep, Père David deer, giraffe); in the sea (bottlenose dolphin, Risso’s dolphin, long-finned pilot whale, Cuvier’s beaked whale, sperm whale and fin whale); or in an amphibious environment (hippopotamus). We also sampled and studied the visual cortex of the horse (a closely related perissodactyl) and two primates (chimpanzee and pig-tailed macaque) for comparison. Our histochemical and immunohistochemical results indicate that the visual cortex of Cetartiodactyls is characterized by a peculiar organization, structure, and complexity of the cortical column. We noted a general lesser lamination compared to simians, with diminished density, and an apparent simplification of the intra- and extra-columnar connections. The presence and distribution of calcium-binding proteins indicated a notable absence of parvalbumin in water species and a strong reduction of layer 4, usually enlarged in the striated cortex, seemingly replaced by a more diffuse distribution in neighboring layers. Consequently, thalamo-cortical inputs are apparently directed to the higher layers of the column. Computer analyses and statistical evaluation of the data confirmed the results and indicated a substantial correlation between eye placement and cortical structure, with a markedly segregated pattern in cetaceans compared to other mammals. Furthermore, cetacean species showed several types of cortical lamination which may reflect differences in function, possibly related to depth of foraging and consequent progressive disappearance of light, and increased importance of echolocation.

“…The initial study has reported the sustained increase of fronto‐central N1 component in response to 1000‐Hz tone after its presentation with a frequency of 13 Hz for 2 min (Clapp et al, 2005). The same experimental design has been used in three more studies (Lei et al, 2017; Rygvold et al, 2021; Teo et al, 2014), although with rather inconsistent results as the N1 increase has been replicated only in one study but at the different posterior region (Lei et al, 2017), while other studies have found a significant increase of N1‐P2 peak‐to‐peak or P2 amplitude (Rygvold et al, 2021; Teo et al, 2014). Thus, the ERP effects of auditory tetanization need additional examination.…”

“…In addition, we aimed to probe if the tetanization effects can be observed in less challenging experimental conditions that are more appropriate, for example, for clinical groups or children. For this purpose, the experimental block that fully reproduced the original Clapp's design where participants have to fixate on the cross in the middle of the screen as used in Clapp et al (2005), Teo et al (2014), and Rygvold et al (2021) was supplemented by sequences where participants watched muted movies while listening to sounds. We chose not to adopt a paradigm where participants close their eyes and listen to stimuli as used by Lei and colleagues (Lei et al, 2017), as this is prone to induction of drowsiness (Oken et al, 2006).…”

A fuller understanding of the effects of auditory tetanization in humans would inform better language and sensory learning paradigms; however, there are still unanswered questions. Here, we probe sustained changes in the event‐related potentials (ERPs) to 1020‐ and 980‐Hz tones following a rapid presentation of 1020‐Hz tone (every 75 ms, 13.3 Hz, tetanization). Consistent with some previous studies, we revealed the increase in the P2 ERP component after tetanization. Contrary to some other studies, we did not observe the expected N1 increase after tetanization even in the identical experimental sequence. We detected a significant N1 decrease after tetanization. Expanding previous research, we showed that P2 increase and N1 decrease are not specific to the stimulus type (tetanized 1020 Hz and non‐tetanized 980 Hz), suggesting the generalizability of tetanization effect to the not‐stimulated auditory tones, at least to those of the neighbouring frequency. The ERPs' tetanization effects were observed for at least 30 min—the most prolonged interval examined, consistent with the duration of long‐term potentiation, LTP. In addition, the tetanization effects were detectable in the blocks where the participants watched muted videos, an experimental setting that can be easily used in children and other challenging groups. Thus, auditory 13‐Hz stimulation affects brain processing of tones including those of neighbouring frequencies.
