The ability to prepare movement is an essential requirement for the control of goal-directed actions. It allows us to respond in an adaptable and swift manner to environmental conditions. In the present study, we manipulate cognitive context, by means of response probability, to modify the degree of movement preparation in a delayed cueing task performed with the right hand, and evaluate the neural dynamics (EEG coherence) and behavioural output (reaction time). Task-related coherence was stronger over the contralateral hemisphere. In particular, coherence between the left sensorimotor area and frontal (C3-F3, C3-FC3) and parietal (C3-P3) regions was increased during right-hand movement preparation as compared to rest in the alpha frequency band (8-12 Hz). Reducing response probability diminished the degree of functional coupling between C3-F3 and C3-FC3, and was associated with a prolonged reaction time. These findings suggest an association between neural dynamics and behavioural performance and emphasize that response predictability biases information processing in goal-oriented behaviour.

Polyurethane sponge is frequently selected as a substrate material for constructing flexible compressible sensors due to its excellent resilience and compressibility. However, being highly hydrophilic and flammable, it not only narrows the range of use of the sensor but also poses a great potential threat to human safety. In this paper, a conductive flexible piezoresistive sensor (CHAP-PU) with superhydrophobicity and high flame retardancy was prepared by a simple dip-coating method using A-CNTs/HGM/ADP coatings deposited on the surface of a sponge skeleton and modified with polydimethylsiloxane.

Background: Drug-resistant epilepsy (DRE) secondary to hypothalamic hamartoma (HH) often requires surgical resection or stereotactic radiosurgery, which frequently fail to provide satisfactory outcomes and are associated with severe side effects. Magnetic resonance-guided focused ultrasound (MRgFUS) may represent a minimally invasive surgical approach to HH by offering precise thermal ablation of sub-millimetric brain targets while sparing surrounding structures.
Methods: We present the case of a 19-year-old man with HH-associated DRE, who was successfully treated with MRgFUS.

Advanced footwear technology (AFT) has gained popularity among non-elite runners due to its potential benefits in training and competition. This study investigated the training practices and reported outcomes in non-elite runners using AFT. A cross-sectional observational study was conducted with 61 non-elite runners competing in distances ranging from 5 km to marathons.

Introduction: Visual feedback plays a crucial role in goal-directed tasks, facilitating movement preparation and execution by allowing individuals to adjust and optimize their movements. Enhanced movement preparation and execution help to increase neural activity in the brain. However, our understanding of the neurophysiological mechanisms underlying different types of visual feedback during task preparation and execution remains limited.

Background: Regular training for mass casualty incidents at physical simulation events is vital for emergency services. The preparation and execution of these simulations consume huge amounts of time, personnel, and money. It is therefore important to gather as much information as possible from each simulation while minimizing any influence on the participants, so as to keep the simulation as realistic as possible.
