Artificially Weaved Textile‐like Surface Micromachined Graphene‐Polymer Flexible Bioelectrodes

Advanced Materials Technologies, EarlyView.
This study reports on the engineering of microscale textured surfaces of SU‐8/PMMA polymer composites much like a “weft‐warp” pattern to resemble “artificially‐weaved” textiles. These microstructured surfaces enable conformal layering of functional reduced graphene oxide (rGO), all‐in‐all offering favorable features including remarkable self ...

Intelligent Eye Tracker Integrated with Cylindrical Capacitive Sensors for Chronic Fatigue Assessment

Advanced Sensor Research, EarlyView.
A wearable capacitive eye tracker for chronic fatigue assessment is presented, utilizing cylindrically shaped capacitive sensors made of a carbon nanotube‐paper composite. By integrating a novel fatigue‐induction protocol with machine learning, the device achieves 0.75‐sensitivity and 0.73‐specificity, providing a practical alternative to existing ...

Asymmetric Inter‐Hemisphere Communication Contributes to Speech Acquisition of Toddlers with Cochlear Implants

Advanced Science, EarlyView.
The present study constructs machine‐learning models to resolve developmental relationships among auditory performance, auditory cortical processing, and functional connectivity of the bilateral language network during the first year of restored hearing. The results demonstrate that asymmetric inter‐hemisphere communication contributes significantly to

Head model and electrical source imaging: A study of 38 epileptic patients

NeuroImage: Clinical, 2014
Electrical source imaging (ESI) aims at reconstructing the electrical brain activity from scalp EEG. When applied to interictal epileptiform discharges (IEDs), this technique is of great use for identifying the irritative zone in focal epilepsies ...

Neural Plasticity and Hearing‐Speech Development in Children with Auditory Brainstem Implants for Congenital Hearing Loss Due to Severe Inner Ear Malformation

Advanced Science, EarlyView.
Data from a prospective cohort with 112 auditory brainstem implant users are analyzed. Younger age at implantation (<3 years), less severe inner‐ear malformation (common cavity, cochlear aplasia, and hypoplasia), and more intraoperative eABR evoked electrodes (≥60%) are associated with better hearing and speech outcomes.

Activation of Glutamatergic Neurons in the Supramammillary Nucleus Promotes the Recovery of Consciousness under Sevoflurane Anesthesia

Advanced Science, EarlyView.
Selective lesioning of SuM glutamatergic neurons promoted the induction of and delayed emergence from sevoflurane anesthesia and increased sevoflurane sensitivity. Optogenetic stimulation of SuM glutamatergic neurons or the SuM‐MS projection promoted behavioral arousal and cortical activation under steady‐state sevoflurane anesthesia and reduced the ...

Perceived synchrony for realistic and dynamic audiovisual events

Frontiers in Psychology, 2015
In well-controlled laboratory experiments, researchers have found that humans can perceive delays between auditory and visual signals as short as 20 ms. Conversely, other experiments have shown that humans can tolerate audiovisual asynchrony that exceeds
