TMS with fast and accurate electronic control: Measuring the orientation sensitivity of corticomotor pathways
Brain Stimulation. 2022.
• Adjustment of the stimulation orientation at 1° steps in submillisecond intervals.
• Multi-coil TMS enables automated, closed-loop brain stimulation protocols.
• The orientation sensitivity of motor responses follows a logistic function.
• The logistic model captures neurophysiological properties of neuronal excitation.

Multi-channel TMS electronically changes the stimulus orientation in milliseconds.
The effect of neuronal refractoriness, short-interval intracortical inhibition, and intracortical facilitation depends on the stimulus orientation.
Maximum inhibition and facilitation with conditioning pulse at posterolateral and anteromedial orientation, respectively. ...

Background: Motor resonance reflects the activation of the motor system during the observation of others’ actions and is considered a physiological marker of the human mirror neuron system (MNS). This study investigated whether the excitatory and inhibitory balance in the primary motor cortex, driven by glutamatergic and GABAergic mechanisms, is linked to the strength of ...

Letter recognition is assumed to involve several levels of analysis, including coarse tuning for category and novelty and more fine tuning for specific features, related to letter orientation. We employed an oddball fast periodic visual stimulation (FPVS) paradigm with magnetoencephalography (Elekta VectorView, 306 sensors) to study neural discrimination responses in the source space. Using contrasts ...

In this work we present an experiment in which we injected microspheres at low pressure into a capacitively coupled argon plasma chamber. The setup was located in the top point of the Einstein-Elevator drop tower in Hannover, Germany, where the microparticles reached their equilibrium position above the lower electrode during 1 g. During the fall, ...

We observed a statistically significant decrease in reaction time during the process of learning within the SRT task and motor facilitation during action observation, thus reflecting putative mirror neuron activity. We found a significant correlation between the learning speed of the non-dominant hand and mirror neuron activation in the dominant hemisphere during the observation of ...

A numerical simulation of a positive streamer in long (up to 3 m) air gaps under normal conditions was performed within the 1.5D model taking into account the ionization expansion of the channel. It is shown that the average electric field in the channel and the field required to bridge the discharge gap are not ...

Recent studies of thunderstorm-related enhancements of fluxes of energetic radiation and particles at ground level suggest that removal of mid-level negative charge from the cloud by negative cloud-to-ground (-CG) lightning flashes or normal intracloud (IC) flashes serves to abruptly terminate those enhancements. However, it was not clear if the electron-accelerating electric field responsible for flux ...

На основе обобщения отечественного и мирового опыта рассматривается комплекс вопросов, связанных с разработкой эффективных экранов для радиоэлектронной аппаратуры (РЭА), работающей в широком частотном диапазоне. Защита РЭА от воздействия электромагнитных полей представлена комплексно: от концепции экранирования до методики расчета неоднородных экранов; от металлических материалов до перспективных композитных и наноматериалов, применяемых при экранировании. В пособии рассматривается концепция ...

While polarity-specific after-effects of monopolar transcranial direct current stimulation (tDCS) on corticospinal excitability are well-documented, modulation of vital parameters due to current spread through the brainstem is still a matter of debate, raising potential concerns about its use through the general public, as well as for neurorehabilitation purposes. We monitored online and after-effects of monopolar ...

Experiments indicating acceleration of charged particles as a result of separation of solid surfaces are analyzed. As a possible mechanism of such acceleration, generation of surface charge on the separated surfaces of a cleaved ionic crystal is considered. The maximum electric field generated due to the charging of the separated surfaces and the energy of ...
