This report is the second part of a comprehensive two-part series aimed at reviewing an extensive and diverse toolkit novel methods to explore brain health function. While first focused on neurophotonic tools mostly applicable animal studies, here, we highlight optical spectroscopy imaging relevant noninvasive human studies. We outline current state-of-the-art technologies software advances, most recent impact these neuroscience clinical applications, identify areas where innovation needed,...
Virtual reality platforms capable of assisting rehabilitation must provide support for principles: promote repetition, task oriented training, appropriate feedback, and a motivating environment. As such, development these is complex process which has not yet reached maturity. This paper presents our efforts to contribute this field, presenting Gesture Therapy, virtual reality-based platform the upper limb. We describe system architecture main features preliminary evidence feasibility in its...
Significance: Intracranial pressure (ICP), variability in perfusion, and resulting ischemia are leading causes of secondary brain injury patients treated the neurointensive care unit. Continuous, accurate monitoring cerebral blood flow (CBF) ICP guide intervention ultimately reduce morbidity mortality. Currently, only invasive tools used to monitor at high risk for intracranial hypertension. Aim: Diffuse correlation spectroscopy (DCS), a noninvasive near-infrared optical technique, is...
Chaotic systems are hard to synchronize, and no general solution exists. The presence of hidden attractors makes finding a particularly elusive. Successful synchronization critically depends on the control strategy, which must be carefully chosen considering system features such as attractors. We studied feasibility fuzzy for synchronizing chaotic with employed special numerical integration method that takes advantage oscillatory characteristic systems. hypothesized can successfully deal...
Background: Gesture Therapy is an upper limb virtual reality rehabilitation-based therapy for stroke survivors. It promotes motor rehabilitation by challenging patients with simple computer games representative of daily activities self-support. This has demonstrated clinical value, but the underlying functional neural reorganization changes associated this that are responsible behavioral improvements not yet known. Objective: We sought to quantify occurrence strategies underlie as they occur...
To investigate the impact of time pressure (TP) on prefrontal activation and technical performance in surgical residents during a laparoscopic suturing task.Neural mechanisms enabling surgeons to maintain cope with operative stressors are unclear. The cortex (PFC) is implicated due its role attention, concentration, monitoring.A total 33 [Postgraduate Year (PGY)1-2 = 15, PGY3-4 8, PGY5 10] performed task under "self-paced" (SP) "TP" conditions (TP maximum 2 minutes per knot). Subjective...
The adenoma detection rate (ADR) is an important quality indicator in colonoscopy. aim of this study was to evaluate the changes visual gaze patterns (VGPs) with increasing polyp (PDR), a surrogate marker ADR.18 endoscopists participated study. VGPs were measured using eye-tracking technology during withdrawal phase characterized two analyses - screen and anatomy. Eye-tracking parameters used characterize performance, which further substantiated hidden Markov model (HMM) analysis.Subjects...
Minimally invasive and robotic surgery changes the capacity for surgical mentors to guide their trainees with control customary open surgery. This neuroergonomic study aims assess a "Collaborative Gaze Channel" (CGC); which detects trainer gaze-behavior displays point of regard trainee. A randomized crossover was conducted in twenty subjects performed simulated task necessitating collaboration either verbal (control condition) or visual guidance CGC (study condition). Trainee...
The prefrontal cortex (PFC) is known to be vital for acquisition of visuomotor skills, but its role in the attainment complex technical skills which comprise both perceptual and motor components, such as those associated with surgery, remains poorly understood. We hypothesized that response a surgical knot-tying task would highly dependent on expertise, activation wane context learning success following extended practice. present series experiments investigated this issue, using functional...
To test the hypothesis that fatigue-induced performance decline in surgical residents is associated with changes brain function as detected by functional near-infrared spectroscopy.Surgical (n = 7) participated a prospective study involving 2-hourly objective measurements of neurocognitive skill (arithmetic calculations using Nintendo "brain training"), technical (surgical knot tying on trainer, and monitoring time taken, path length number movements), introspective fatigue...
The use of multiple robots for performing complex tasks is becoming a common practice many robot applications. When different operators are involved, effective cooperation with anticipated manoeuvres important seamless, synergistic control all the end-effectors. In this paper, concept Collaborative Gaze Channelling (CGC) presented improved surgical shared task. Through eye tracking, fixations each operator monitored and in workspace. CGC permits remote or physically separated collaborators...
between measures from the MUSIC registry and complication rates scorecard (Figure).Discussion | For urologists in Michigan, we found no significant correlation reported Surgeon Scorecard perioperative quality a statewide improvement collaborative.This finding supports prevalent concern that limited data available provide an incomplete, if not inaccurate, assessment of surgeon performance. 4 However, there are other potential explanations for our findings.First, because dates included...
Abstract In premature infants with an extremely low gestational age (ELGA, < 29 weeks GA), dysregulated changes in cerebral blood flow (CBF) are among the major pathogenic factors leading to germinal matrix/intraventricular hemorrhage (GM/IVH). Continuous monitoring of CBF can guide interventions minimize risk brain injury, but there no clinically standard techniques or tools for its measurement. We report feasibility continuous CBF, including measures autoregulation, via diffuse...
In Brief Objective: Using eye-tracking technology, we aim to examine if there are common patterns of visual attention strategies employed by surgeons which associated with a greater chance successful reorientation when disorientated during laparoscopic cholecystectomy. Summary Background Data: Laparoscopic cholecystectomy is one the most commonly practiced and minimally invasive procedures recognized morbidity relating bile duct injuries. It has been suggested that majority injuries occur as...
It is well established that disorientation during laparoscopic operations such as cholecystectomy associated with increased morbidity and mortality. The aim of the present study was to evaluate whether high-performance orientation strategies could be taught a cohort without relevant experience cholecystectomy, resulting in improved performance spatial awareness, thereby reducing need for operative command this skill.Thirty medical students participated randomized controlled trial, half...
