Characterization of a conductive hydrogel@Carbon fibers electrode as a novel intraneural interface.

Peripheral neural interfaces facilitate bidirectional communication between the nervous system and external devices, enabling precise control for prosthetic limbs, sensory feedback systems, and therapeutic interventions in the field of Bioelectronic Medicine. Intraneural interfaces hold great promise since they ensure high selectivity in communicating only with the desired nerve fascicles. Despite significant advancements, challenges such as chronic immune response, signal degradation over time, and lack of long-term biocompatibility remain critical considerations in the development of such devices.

Beyond the limiting gap length: peripheral nerve regeneration through implantable nerve guidance conduits.

Peripheral nerve damage results in the loss of sensorimotor and autonomic functions, which is a significant burden to patients. Furthermore, nerve injuries greater than the limiting gap length require surgical repair. Although autografts are the preferred clinical choice, their usage is impeded by their limited availability, dimensional mismatch, and the sacrifice of another functional donor nerve.

Direct laser writing of liquid crystal elastomers oriented by a horizontal electric field.

The ability to fabricate components capable of performing actuation in a reliable and controlled manner is one of the main research topics in the field of microelectromechanical systems (MEMS). However, the development of these technologies can be limited in many cases by 2D lithographic techniques employed in the fabrication process. Direct Laser Writing (DLW), a 3D microprinting technique based on two-photon polymerization, can offer novel solutions to prepare, both rapidly and reliably, 3D nano- and microstructures of arbitrary complexity.

Discrimination of Object Curvature Based on a Sparse Tactile Sensor Array.

Object curvature plays an important role in grasping and manipulation. To be more exact, local curvature is a more useful information for grasping practically. Vision and touch are the two main methods to extract surface curvature of an object, but vision is often limited since the complete contact area is invisible during manipulation.

Sleep disturbances in specific learning disorders: a qualitative and quantitative investigation.

Background: The literature reports a significant association between sleep disorders and learning disabilities. Nevertheless, not all children with learning disorders have sleep alterations, and which sleep characteristics are associated with which learning difficulty is still unknown. The study aimed at acquiring new information on the relation between sleep disturbances or habits and the learning profiles of children with a specific learning disorder (SLD).

Delta Power Is Higher and More Symmetrical in Ischemic Stroke Patients with Cortical Involvement.

A brain injury resulting from unilateral stroke critically alters brain functionality and the complex balance within the cortical activity. Such modifications may critically depend on lesion location and cortical involvement. Indeed, recent findings pointed out the necessity of applying a stratification based on lesion location when investigating inter-hemispheric balance in stroke.

Electrophysiological and microstructural features of sleep in children at high risk for depression: a preliminary study.

Objective: This preliminary study investigated electrophysiological and microstructural features of sleep in children and adolescents 4-18 years of age who were born to depressed mothers.

Methods: A total of 31 healthy subjects (15 male and 16 female) participated in the study. In this sample, 20 children born to mothers diagnosed with Major Depressive Disorder (MDD) were designated as "high-risk"; 11 children born to mothers without a personal history of depression were designated as "low-risk.

Design and evaluation of NEUROBike: a neurorehabilitative platform for bedridden post-stroke patients.

Over the past decades, a large number of robotic platforms have been developed which provide rehabilitative treatments aimed at recovering walking abilities in post-stroke patients. Unfortunately, they do not significantly influence patients' performance after three months from the accident. One of the main reasons underlying this result seems to be related to the time of intervention.
