Sensory gating is important for preventing excessive environmental stimulation from overloading neural resources. Gating in the human somatosensory cortices a critically understudied topic, particularly lower extremities. We utilize unique capabilities of magnetoencephalographic neuroimaging to quantify normative population responses and dynamic functional connectivity extremities healthy participants. show that processing subserved by robust effect oscillatory domain, as well on...

The neuroimaging literature on cerebral palsy (CP) has predominantly focused identifying structural aberrations within the white matter (e.g., fiber track integrity), with very few studies examining neural activity key networks that serve production of motor actions. current investigation used high-density magnetoencephalography to begin fill this knowledge gap by quantifying temporal dynamics alpha and beta cortical oscillations in children CP (age = 15.5 ± 3 years; GMFCS levels II–III)...

Abstract Multiple sclerosis (MS) is a demyelinating disease that results in broad array of symptoms, including impaired motor performance. How such demyelination fibers affects the inherent neurophysiological activity circuits, however, remains largely unknown. Potentially, movement errors associated with MS may be due to imperfections internal model used make predictions output will meet task demands. Prior magnetoencephalographic (MEG) and electroencephalographic brain imaging experiments...

When identical stimuli are presented in rapid temporal succession, neural responses to the second stimulation often weaker than those observed for first. This phenomenon is termed sensory gating and believed be an adaptive feature that helps prevent higher-order cortical centers from being flooded with unnecessary information. Recently, somatosensory system has been linked deficits tactile discrimination. Additionally, studies have poor discrimination impaired walking balance individuals...

Although it is well appreciated that practicing a motor task updates the associated internal model, still unknown how cortical oscillations linked with action change practice. The present study investigates short-term changes (e.g., fast learning) in α- and β-event-related desynchronizations (ERD) production of action. To this end, we used magnetoencephalography to identify β-ERD healthy adults after participants practiced novel isometric ankle plantarflexion target-matching task. After...

Abstract Adolescents demonstrate increasing mastery of motor actions with age. One prevailing hypothesis is that maturation the somatosensory system during adolescence contributes to improved control. However, limited efforts have been made determine if cortical processing different in adolescents movement. In this study, we used magnetoencephalographic brain imaging begin addressing knowledge gap by applying an electrical stimulation tibial nerve as (Age = 14.8 ± 2.5 yrs.) and adults 36.8...

This paper describes building information modeling (BIM) research by students and faculty of the University Nebraska’s Peter Kiewit Institute (PKI). The also work in conjunction with United States Strategic Command (USSTRATCOM), located at Offutt Air Force Base Omaha, Nebraska, USA. objective this on-going is to create a virtual environment where architects planners can present concepts design options customers way that more easily envisioned client. proposed would integrate BIM environments...

Key points Magnetoencephalography data were acquired during a leg force task in pre‐/post‐practice sessions adolescents and adults. Strong peri‐movement alpha beta oscillations mapped to the cortex. Following practice, performance improved altered. Beta decreased sensorimotor cortex after but increased No differences detected for oscillations. Abstract There is considerable evidence that there are motor practice between Behavioural studies have suggested these simply due experience. However,...

Cortical visual processing in MT/V5 is necessary for tracking movement and performing reliable visuomotor transformations. Although the role of this cortical area well recognized, activity children with cerebral palsy (CP) has not been examined nor its potential atypical motor actions these considered. This study used magnetoencephalography to image neural motion-sensitive cortices typically developing (TD) (n = 21; mean age 14 yrs. ± 2, 12 males) CP 16 4, 13 as they viewed a horizontally...

Abstract Cometrics is a Microsoft Windows compatible clinical tool for the collection and recording of frequency- duration-based target behaviors, physiological signals, video data. This software package designed to record in-vivo observational In addition, we have included features that allow observers capture from real-time camera feeds import saved retroactive data collection. By using Excel-based spreadsheets, also called keystroke files, assessment treatment sessions are exported into...

The aim of the study was to evaluate feasibility virtual reality (VR) software built using core concepts hand-arm bimanual intensive training (HABIT) for improving upper extremity motor function in children with cerebral palsy (CP).Eight CP participated a 10-day, 40-hour HABIT program. Half time custom VR software, HABIT-VR used. children's skills were assessed pre- and postintervention Assisting Hand Assessment, Box Blocks Test, Nine-Hole Peg Test.The had significant clinically relevant...

Abstract This study's purpose is to introduce a new measurement system that objectively assesses the social validity of behavioral feeding intervention from child's perspective via concurrent two dimensions emotion . To date, primary measures for are caregiver treatment acceptability and satisfaction surveys. first study measure emotion, physiological arousal emotional valence, while children received difficulties. Data collectors used open‐source data collection software, cometrics,...

This single-participant case study examines the feasibility of using custom virtual reality (VR) gaming software in home environment for low-dose Hand Arm Bimanual Intensive Training (HABIT). A 10-year-old with right unilateral cerebral palsy participated this trial. Fine and gross motor skills as well personal goals outcomes were assessed before after intervention Box Blocks Test, Nine-Hole Peg Canadian Occupational Performance Measure.

Many clinical spaces are outfitted with centralized video recording systems to monitor patient-client interactions. Considering the increasing interest in video-based machine learning methods, potential of using these recordings automate observational data collection is apparent. To explore this, seven patients had videos their functional assessment and treatment sessions annotated by coders trained our team. Commonly used software has inherent limitations aligning behavioral data, so a...
