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.

Rectangularity can be an a priori constraint for the visual system to recover a 3D shape from a 2D image. Two psychophysical experiments (n = 16 each) were conducted to test whether observers are biased to perceive trihedral corners as rectangular and whether this bias is perceptual rather than a response bias. The results of ...

The study examines emotional responses to words representing a wide range of psychological valence and focuses on gender-related differences. We aimed to find out whether men and women differ in their emotional responses, and whether they can take the perspective of another gender.

Several theories suggest that individual differences in the notion of the self are associated with relationship to nature and pro-environmental behavior. However, the diversity of existing theories makes it difficult to test this hypothesis in a comprehensive way. We combined a wide range of relevant constructs to explore whether self-centeredness (operationalized as a combination of ...

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 ...
