Low-contrast Pattern-reversal Visual Evoked Potential in Different Spatial Frequencies

Journal of Ophthalmic & Vision Research, 2020
Purpose: To evaluate the pattern-reversal visual evoked potential (PRVEP) in low-contrast, spatial frequencies in time, frequency, and time-frequency domains. Methods: PRVEP was performed in 31 normal eyes, according to the International Society of

Localized Temperature Monitoring in Mouse Brain during Light Delivery via a Non‐Planar Tapered Fiber‐Integrated µRTD Sensor

Advanced Materials, EarlyView.
We report a multifunctional tapered optical fiber integrating a conformal micro‐resistance temperature detector (µRTD) for local, real‐time thermometry during optical stimulation. The platform combines light‐delivery and temperature sensing within a minimally invasive footprint, enabling detection of sub‐degree cortical heating under representative ...

Cross-Modal Functional Reorganization of Visual and Auditory Cortex in Adult Cochlear Implant Users Identified with fNIRS

Neural Plasticity, 2016
Cochlear implant (CI) users show higher auditory-evoked activations in visual cortex and higher visual-evoked activation in auditory cortex compared to normal hearing (NH) controls, reflecting functional reorganization of both visual and auditory ...

Self‐Powered Flexible Triboelectric‐Gated Ion‐Gel Transistor for Neuromorphic Tactile Sensing and Human Activity Recognition

Advanced Materials, EarlyView.
A fully flexible ion‐gel‐gated graphene‐channel transistor driven by a triboelectric nanogenerator enables self‐powered tactile sensing and synaptic learning. Mimicking spike‐rate‐dependent plasticity, the device exhibits frequency‐selective potentiation and depression, supporting rate‐coded neuromorphic computation even under flex.

Contrast sensitivity study in patients with Anisometropia Amblyopia

Journal of the Egyptian Ophthalmological Society
Background Contrast sensitivity is the ability of the eye to detect small changes in illumination at targets that do not have clearly defined limits. Amblyopia is a disorder of sight in which the brain fails to process inputs from one eye and over time ...

Saccade-related modulations of neuronal excitability support synchrony of visually elicited spikes [PDF]

, 2011
During natural vision, primates perform frequent saccadic eye movements, allowing only a narrow time window for processing the visual information at each location.

Turning Unpredictable Biomolecule Adsorption to Controlled Corona Formation: Focus on Carbon Nanomaterials

Advanced Materials, EarlyView.
Controlling the protein corona formation onto carbon nanomaterials (CNMs) enhances their functionalities as platforms for cancer theranostics. Here, we reviewed the effects of the intrinsic and acquired properties of CNMs on protein corona formation, the consequent biological and toxicological outcomes, and the strategies to reshape corona formation ...

Association between Visual Evoked Potential and Disease Severity, Disease Duration and Visual Hallucination in Patients with Idiopathic Parkinsonism

Novelty in Biomedicine, 2014
Background: Parkinson's disease (PD) is a neurodegenerative disorder impairing motor, verbal and other abilities. Visual evoked potential (VEP) assessment is a useful method for analysis of visual system and its function.

Ratiometric Mycotoxin Detection in Living Plants With Dual‐Emissive Nanosensors

Advanced Materials, EarlyView.
A minimally invasive microneedle patch integrates carbon dot‐embedded metal–organic frameworks as nanosensors to detect a key fungal toxin in living plants. The nanosensor produces a ratiometric fluorescence signal that enables early, non‐destructive diagnosis of fungal infection before visible symptoms, offering a new biomaterials‐based strategy for ...
