Enhanced somatosensory inhibition sharpens hand representation and sensorimotor skills in pianists.
J Neurosci
January 2025
Sony Computer Science Laboratories Inc., Tokyo, Japan.
Dexterous motor skills, like those needed for playing musical instruments and sports, require the somatosensory system to accurately and rapidly process somatosensory information from multiple body parts. This is challenging due to the convergence of afferent inputs from different body parts into a single neuron and the overlapping representation of neighboring body parts in the somatosensory cortices. How do trained individuals, such as pianists and athletes, manage this? Here, a series of five experiments with pianists and nonmusicians (female and male) shows that pianists have enhanced inhibitory function in the somatosensory system, which isolates the processing of somatosensory afferent inputs from each finger.

The replacement of an Atomic Force Microscope (AFM) probe is inevitable due to blunting or contamination of its tip during usage. The fabrication of AFM probes is a complex and costly process, and the mechanical properties of these probes need to be calibrated due to material defects before use, making this procedure intricate. Taking inspiration from the Wollaston probe, we have developed a T-shaped tungsten probe and installed it into a home-made scanning probe microscope.

Reliable and consistent preparation of atom probe tomography (APT) specimens from aqueous and hydrated biological specimens remains a significant challenge. One particularly difficult process step is the use of a focused ion beam (FIB) instrument for preparing the required needle-shaped specimen, typically involving a 'lift-out' procedure of a small sample of material. Here, two alternative substrate designs are introduced that enable using FIB only for sharpening, along with example APT datasets.

Objective: Viewing that there is a lack of valid and reliable measures to assess visual literacy in clinical and healthcare settings, this study aimed to develop a visual literacy scale to assess health students' and professionals' visual literacy, by which teachers can further help them sharpen their visual literacy skills and sensitivity to let them reach effective communication in clinical and healthcare settings.
Methods: The scale was constructed according to Slavec and Drnovšek's three-phase scale development process: theoretical significance and existence of the scale construct, representative data collection and appropriate data collection methods, and statistical analysis of data collection and statistical evidence of the scale construct. To investigate the psychometrical properties, the researchers first performed a pilot study on randomly selected 464 health students and professionals, using exploratory factor analysis (EFA) with SPSS to derive the hidden factor structure, and then on randomly selected 303 participants, using confirmatory factor analysis (CFA) with AMOS to validate the derived factor structure.
Efficacy of two diode lasers in the removal of calculus from the root surface: An in vitro study.

Introduction: Scaling and root planning (SRP) is still the gold standard of nonsurgical periodontal therapy, and it has been accompanied by several supportive therapies in recent years. One of the most studied methods is the diode laser, thanks to its thermal and bactericidal properties. Our trial intended to verify whether it could influence the chemical bond between calculus and the root surface.
