“…As a result, we have a low SNR here as well. However, an ERP component gives rise to a maximum of the SNR at a critical threshold h*, indicating most probable threshold crossing events in the positive or negative direction, or, technically speaking, an aperiodic stochastic resonance effect [4,25,26].…”

Previous ERP studies have found an N400-P600 pattern in sentences in which the number of arguments does not match the number of arguments that the verb can take. In the present study, we elaborate on this question by investigating whether the case of the mismatching object argument in German (accusative/direct object versus dative/indirect object) affects processing differently. In general, both types of mismatches elicited a biphasic N400-P600 response in the ERP. However, traditional voltage average analysis was unable to reveal differences between the two mismatching conditions, that is, between a mismatching accusative versus dative. Therefore, we employed a recently developed method on ERP data analysis, the symbolic resonance analysis (SRA), where EEG epochs are symbolically encoded in sequences of three symbols depending on a given parameter, the encoding threshold. We found a larger proportion of threshold crossing events with negative polarity in the N400 time window for a mismatching dative argument compared to a mismatching accusative argument. By contrast, the proportion of threshold crossing events with positive polarity was smaller for dative in the P600 time window. We argue that this difference is due to the phenomenon of bfree dativeQ in German. This result also shows that the SRA provides a useful tool for revealing ERP differences that cannot be discovered using the traditional voltage average analysis. D 2005 Elsevier B.V.

“…Stochastic resonance (SR) [1][2][3][4] occurs when a weak periodic signal in a nonlinear system is amplified by a noise of appropriate strength. In bistable systems, it has been shown that other types of external driving can mimic the role of noise in the amplification of the signal.…”

We study the overdamped version of two coupled anharmonic oscillators under the influence of both low-and high-frequency forces respectively and a Gaussian noise term added to one of the two state variables of the system. The dynamics of the system is first studied in the presence of both forces separately without noise. In the presence of only one of the forces, no resonance behaviour is observed, however, hysteresis happens there. Then the influence of the high-frequency force in the presence of a low-frequency, i.e. biharmonic forcing, is studied. Vibrational resonance is found to occur when the amplitude of the high-frequency force is varied. The resonance curve resembles a stochastic resonance-like curve. It is maximum at the value of g at which the orbit lies in one well during one half of the drive cycle of the low-frequency force and in the other for the remaining half cycle. Vibrational resonance is characterized using the response amplitude and mean residence time. We show the occurrence of stochastic resonance behaviour in the overdamped system by replacing the high-frequency force by Gaussian noise. Similarities and differences between both types of resonance are presented.

“…More recently, it has been suggested that also noisy electrical fluctuations are able to boost synaptic signals (Moss, et al, 2004). Interestingly, oscillations within a frequency range of 80-200 Hz included in the high frequency band, have been associated with plasticity processes (Grenier, et al, 2001) and learning (Ponomarenko, et al, 2008).…”

“…The neuromodulatory effects of tRNS are said to facilitate or inhibit neuronal activity by syncronising or desyncronising it (Grenier, Timofeev, & Steriade, 2001;Moss, Ward, & Sannita, 2004;Ponomarenko, Li, Korotkova, Huston, & Haas, 2008). Unlike in transcranial direct current stimulation (tDCS), where the neurons are embedded in a constant electrical field and may result in a homeostatic effect of the ion neural channels after prolonged use, random noise stimulation counteracts this phenomenon due to its fluctuating pattern.…”

The application of online transcranial random noise stimulation and perceptual learning in the improvement of visual functions in mild myopia

It has recently been demonstrated how perceptual learning, that is an improvement in a sensory/perceptual task upon practice, can be boosted by concurrent high-frequency transcranial random noise stimulation (tRNS). It has also been shown that perceptual learning can generalize and produce an improvement of visual functions in participants with mild refractive defects.By using three different groups of participants (single-blind study), we tested the efficacy of a short training (8 sessions) using a single Gabor contrast-detection task with concurrent hftRNS in comparison with the same training with sham stimulation or hf-tRNS with no concurrent training, in improving visual acuity (VA) and contrast sensitivity (CS) of individuals with uncorrected mild myopia.A short training with a contrast detection task is able to improve VA and CS only if coupled with hf-tRNS, whereas no effect on VA and marginal effects on CS are seen with the sole administration of hf-tRNS.Our results support the idea that, by boosting the rate of perceptual learning via the modulation of neuronal plasticity, hf-tRNS can be successfully used to reduce the duration of the perceptual training and/or to increase its efficacy in producing perceptual learning and generalization to improved VA and CS in individuals with uncorrected mild myopia.
