An Epigenetic Fate Converter Based on Nuclei‐Targeting Lipid Nanoparticles Drives Neuronal Programming of Stem Cells for Spinal Cord Repair

open access: yesAdvanced Functional Materials, EarlyView.
Schematic illustration of LNP‐MPG nuclei‐targeting delivery of HMW‐FGF2 promoting histone acetylation to regulate the fate of DPSCs and treat spinal cord injury. LNPs components include pHMW‐FGF2 plasmid, DSPC, Dlin‐MC3‐DMA, cholesterol, and PEG2000, and are modified with MPG to form HMW‐FGF2@LNP‐MPG (HLM). HLM nuclei‐targets DPSCs to deliver HMW‐FGF2,

Cue validity and object-based attention [PDF]

open access: yes, 2004
In a previous study, Egly, Driver, and Rafal (1994) observed both space- and object-based components of visual selective attention. However, the mechanisms underlying these two components and the relationship between them are not well understood.

In Situ Magnetic Ordering and Microfabrication of Liquid Crystal Networks with Discretized Alignment

open access: yesAdvanced Functional Materials, EarlyView.
Miniaturizing liquid crystal network actuators typically demands costly laser writing or digital light processing. A low‐cost photolithography platform couples rotating photomasks with a Halbach magnetic array to discretize in‐plane molecular alignment down to 50 µm, producing programmable, light‐responsive grippers, checkerboards, and origami‐inspired

Meta-Analysis of Visual Evoked Potential and Parkinson’s Disease

open access: yesParkinson's Disease, 2018
Background. Previous studies suggested that visual evoked potential (VEP) was impaired in patients with Parkinson’s disease (PD), but the results were inconsistent. Methods.

Analog Classification of Human Hand Gestures Exploiting Dendritic Integration With an Organic Artificial Soma

open access: yesAdvanced Functional Materials, EarlyView.
An organic neuromorphic architecture for the classification of human motor behavior is presented and validated. It performs somatic integration by linearly combining the activity from three muscles. An investigation of synaptic weights is presented and discussed in relationship with the classification performance.

The folding fingerprint of visual cortex reveals the timing of human V1 and V2 [PDF]

open access: yes, 2007
Primate neocortex contains over 30 visual areas. Recent techniques such as functional magnetic resonance imaging (fMRI) have successfully identified many of these areas in the human brain, but have been of limited value for revealing the temporal ...

Visual Evoked Potential Findings of Sjogren's Syndrome [PDF]

open access: yes, 2020
Background: Sjogren’s syndrome is one of the most common autoimmune diseases. These diseases can affect the entire body. Visual system involvement, i.e., dry eye is most common among these Patients.

Additively Manufactured Geometry‐Reconfigurable Soft Neural Probes With Monolithic Multifunctionality

open access: yesAdvanced Functional Materials, EarlyView.
A geometry‐reconfigured additive manufacturing strategy converts planar printed soft materials into soft compact neural probes with integrated hydrogel electrodes and microfluidic channels. The resulting NeuroMAP platform enables scalable multichannel recording, localized chemical delivery, stable in vivo electrophysiological recording, and reduced ...

Young infants' binocular interaction : evoked potential measures [PDF]

open access: yes, 1978
The primary purpose of the dissertation was to determine the presence or absence of binocular interaction in young infants. The anaglyphic (color separation) method of splitting the visual field was employed to present a stimulus continuously to the ...
