The activity of sensorimotor area in the motor learning stage. A recent study revealed an increased a excitability of primary somatosensory cortex (S1) early in learning and increased primary motor cortex (M1) excitability later while achieving a high degree of precision in learning (Ohashi et al., 2019). Furthermore, a previous study indicated that premotor area (PMA) and supplementary motor area (SMA) excitability changes during the motor skill learning process (Grafton et al., 1992). The dexterous finger movement skills were improved when PMA or SMA was stimulated using non-invasive brain stimulation (Pavlova et al., 2014; Hupfeld et al., 2017). Thus, changes in the motor-related cortical area may lead to altering the suppression of somatosensory information during the motor skill learning process.
The present study focused on changes in gating following repetitive practice of motor tasks. We investigated the relationship between the Spain phone number list suppression of somatosensory information and motor skill acquisition using SEPs. In previous studies, SEP components of P25 (P22 in Frontal) reflecting activity in area 3b, N30 in frontal reflecting activity in SMA and PMA, N33 in parietal reflecting activity in area 1, and P45 (P40 in Frontal) reflecting activity in the posterior parietal cortex were reported to be gated during voluntary movement.
Moreover, we performed a correlation analysis of the changes in P45 at C3′ and the changes in the muscle activity of APB. Statistical significance was set at P-values of < 0.05.In their otherwise comprehensive review of signaling mechanisms in sweet taste, von Molitor et al. (2021) missed research on human sweet taste modeling that originated in pharmacokinetics. This research predates the receptor characterization that they reviewed by about a decade and was conducted in humans. The von Molitor et al. paper, published in a journal devoted to human neuroscience, appropriately begins with a background on sugar consumption and health in humans. The paper goes on to provide a brief overview of the severe limitations associated with human experimentation and concludes that “taste-related signaling mechanisms have been studied mainly in rodents, although there are major species-related differences.
