BACKGROUND: Noninvasive brain stimulation effectively affects movements, including the spinal cord level. Stimulation effects are very sensitive to montage and protocols of applied stimulation because they can involve different neuronal mechanisms. AIM: This study aimed to estimate the effect of anodal transspinal direct current stimulation (tsDCS) with an intensity of 2.5 mA applied at the spinal cord level (C7–Th1 segments) with cervical enlargement on the corticospinal system excitability and motor skills. METHODS: The study involved 54 healthy adults aged 21.19±3.2 years. The effect of tsDCS was assessed using motorevoked potentials from the first dorsal interosseous (FDI) muscle by transcranial magnetic stimulation in the primary motor cortex before stimulation, immediately after stimulation, and after 15 min. RESULTS: The application of an 11-min anodal tsDCS with a current value of 2.5 mA at the C7–Th1 level did not affect the motorevoked potentials of FDI. Statistically, changes in motorevoked potentials amplitudes did not differ between groups receiving anodal tsDCS and sham stimulation. In addition, anodal tsDCS did not affect motor skills. An individual’s ability to coordinate fingers and manipulate objects effectively (a measure of dexterity) in the nine-hole peg test and pressing a key in response to a visual stimulus in the serial reaction time task did not differ from that with sham stimulation. CONCLUSION: 2.5 mA anodal tsDCS on cervical enlargement does not affect the corticospinal system excitability or change motor skills associated with precise hand movements.

Currently, artificial intelligence occupies a solid place among traditional pedagogical technologies and approaches, which is the subject of widespread discussion among domestic and foreign scientists and researchers. This is because the introduction of AI into higher education, despite its high potential, faces a wide range of economic, social, and ethical obstacles. These include resistance to ...

В русскоязычной психологической литературе конструкт «агентность» встречается редко и обычно отождествляется с понятием «субъектность». В англоязычном дискурсе при рассмотрении агентности изучают два аспекта: ее ощущение и оценку. Дифференциальный опросник переживания агентности (Sense of Agency Scale) А. Тапал и коллег – ДОПА – направлен на измерение общего ощущаемого контроля над собственными произвольными действиями. Целью текущего исследования ...

Large language models (LLMs) have been proposed as a substitute for field trials in itemdifficulty estimation, but evidence about where they succeed is usually drawn from a single test form. We compare LLM difficulty predictions across three task types that make different language demands, grammar cloze, semantic cloze and reading comprehension, on two operational Grade ...

Being able to remember the origin of a particular memory is for times even more important than the memory itself. Yet, although memory for the information and memory for the source are intrinsically connected, the particular neural underpinnings for the source‐memory monitoring remains unclear. We run an fMRI meta‐analysis to help to clarify the brain ...

The increasing prevalence of technology in daily life has led to a rising demand for IT specialists. In response, educational curricula have been adapted to incorporate coding lessons as early as primary school. However, the cognitive processes underlying computational thinking (CT) — the ability to apply a systematic problem-solving approach akin to computer logic — ...

The rapid proliferation of misinformation in digital environments poses a serious threat to public health, political institutions, and public discourse. Behavioral research has accumulated substantial evidence on why people believe and share false information, yet individual studies address cognitive biases, social factors, or emotional processes largely in isolation. Additionally, the influential integrative frameworks that do ...

The dynamics of opinion in a group are of interest for a number of practical purposes. In particular, consensus helps and polarization of opinions hinders cohesive teamwork. Existing approaches for modeling opinion dynamics mostly do not take into account the dynamism of social relations in a group. This paper proposes an algorithm and a program ...

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 ...

Context. The preschool period is a critical stage for the development of prosocial behavior. Children begin to understand the feelings of others, and the foundations of empathy and mutual assistance are formed. Situation-specific expressions of care can develop into more stable forms when children are embedded in a system of social relationships. However, the specific characteristics ...

We develop a novel cloud-function formalism describing the dynamical relationship between sensory-information processing in large-scale brain networks (supraliminal processing) and the content of the mental representation of an observed object. The formalism combines elements of neural field theory for large-scale neural activity with the spatial characteristics of perceived objects and their embedding in the environment ...

Introduction:
While self-referential attention is thought to enhance interoceptive sensitivity, its effect on cardiac modulation of corticospinal excitability remains unexplored. This pilot study investigated how viewing one’s own face (self-face processing) modulates the cardiac-phase coupling of motor output and whether this heart-brain coupling depends on interoceptive accuracy (heartbeat perception).
Methods:
In 15 healthy adults, motor-evoked potentials (MEPs) were ...

Motor resonance (MoR) refers to the automatic activation of motor circuits during action observation, reflecting an internal simulation of the observed movement. This phenomenon is thought to arise
from the activity of mirror neuron regions, which modulate primary motor cortex (M1) excitability via cortico-cortical pathways. MoR, which is believed to be involved in the mechanism underlying action understanding ...

Transcranial random noise stimulation (tRNS) is a type of transcranial electrical stimulation. tRNS at the primary motor cortex affects corticospinal system (CSS) excitability. We assume that applying analogous protocols at the spinal cord level could similarly influence on CSS excitability, enabling a comparison of stimulation outcomes. This research aims to scrutinize the impact of combining ...
