Summary: In this study, the researchers attempted to replicate the reduction in MEP amplitude associated with the rubber hand illusion (RHI) and identify the components of the illusion that might explain these changes. Despite participants reporting the presence of the illusion and shifts in perceived real hand position towards the fake limb, no reduction in MEP amplitude was observed.

Summary: This study aimed to evaluate the effect of three different sEMG electrode montages on the MEP amplitude. The results showed that different electrode montages can provide contrasting MEP amplitudes, highlighting the need for standard recommendations on electrode placement for MEP recordings.

Summary: This study evaluates the combination of tendon reflex recordings and transcranial magnetic stimulation motor evoked potentials recordings (T-MEPs) at lower limbs in ALS patients. The central motor conduction time yields the highest sensitivity and specificity for detecting upper motor neuron dysfunction. The T/MEP ar is also sensitive and can better identify abnormal hyperreflexia. T-MEPs can detect asymmetries that are missed by clinical examination.

Summary: Transcranial magnetic stimulation (TMS) is a non-invasive technique used to study the human brain. One outcome measure of TMS is the motor-evoked potential (MEP), which estimates changes in corticospinal excitability. This article summarizes the neural pathways and circuits contributing to MEP generation, discusses factors to consider when interpreting MEP amplitude in motor processing and neurological conditions, and explores how emerging technologies can enhance understanding of neural substrates influencing MEPs.

Summary: In this study, a localized stimulation technique for transcranial electrical stimulation motor evoked potentials (TES-MEP) was reported, which induced unilateral MEP responses. Through stimulation in 70 patients, contractions of the contralateral muscles were successfully elicited, enabling stable and safe monitoring of motor function in the unilateral limbs.

Summary: Transcranial magnetic stimulation (TMS) can be used to induce motor evoked potentials (MEPs). This study aimed to characterize the individual near-threshold recruitment of MEPs and determine the proper suprathreshold stimulation intensity (SI). The study found that individual near-threshold characteristics significantly influenced MEP production at suprathreshold SIs and emphasized the importance of selecting the appropriate SI for TMS applications.

Summary: This randomized, double-blinded, placebo-controlled trial investigated the effect of low-dose droperidol on transcranial electrical motor-evoked potentials (TCE-MEP) amplitudes. The results showed that droperidol significantly reduced TCE-MEP amplitudes, highlighting the importance of timing droperidol administration during intraoperative TCE-MEP recordings for anesthesiologists.

Summary: This study evaluated the reliability and validity of ipsilateral motor-evoked potentials (iMEP) induced by transcranial magnetic stimulation in healthy adults. The results showed significant variations in iMEP estimation between different algorithms, and template-based approaches may be more valid. This is important for the selection and development of analysis algorithms for magnetically induced potentials.

Summary: This study investigated the effects of dexmedetomidine on cortical excitability. The results showed that cortical excitability increased in the frontal cortex during light sedation, deep sedation, and recovery. There was also an interaction between dexmedetomidine and brain region on cortical excitability.

Summary: Motor imagery (MI) and neuromuscular electrical stimulation (NMES) are effective stimuli to improve strength, each exhibiting different and specific neural plasticity. However, the combination of NMES + MI did not provide the expected gains, suggesting that their effects may be competitive.

It provides an alternative to mainstream sports with its focus on adaptability and precision landing. Parkour practitioners, known as traceurs, train in urban settings and prefer individualized challenges.

Summary: The present study aimed to investigate the time-course changes in cardiometabolic and neuromuscular responses during the sit-to-stand transition. The results showed rapid adaptation of all systems, with the neuromuscular system adapting the fastest, followed by the hemodynamic system and the metabolic variables. Cardiometabolic and neuromuscular responses were significantly increased during standing compared to sitting. However, the health benefit, particularly in terms of energy expenditure, was relatively modest.

Summary: The purpose of this study was to investigate the acute effect on motor performance and spinal excitability following motor imagery (MI), neuromuscular electrical stimulation (NMES), and the combination of MI and NMES. The results showed that the combination of MI and NMES delayed the onset of neuromuscular fatigue and was associated with specific modulation of spinal excitability. These findings suggest that MI can compensate for the acute neuromuscular fatigue induced by NMES for up to 10 minutes after the combination therapy.

Summary: This study found that anodal stimulation of the left dorsolateral prefrontal cortex (DLPFC) may enhance endurance performance and cognitive function under hypoxic conditions. This effect is likely achieved through increased neural drive to the working muscles, decreased rating of perceived exertion (RPE), and increased perceptual responses.

Summary: Brain-computer interfaces (BCIs) can enable individuals to interact with devices based on their brain activity. However, the high costs associated with research-grade electroencephalogram (EEG) acquisition devices make them impractical for everyday use. This study demonstrates that decoding movement intention from a limited number of sensors is feasible, opening up the possibility of using commercial sensor devices for BCI control.

Summary: This study aimed to investigate the acute effects of different warm-up routines, emphasizing either peripheral (PAPE) or central (MI) contributions on sport-specific tasks. The results showed that both PAPE and MI significantly improved agility and repeated sprint ability, with PAPE being more effective in the 20 m sprint. Reaction time and the NASA-TLX questionnaire were not affected by the warm-up modalities.
