Spectrally Tuned Floating‐Gate Synapse Based on Blue‐ and Red‐Absorbing Organic Molecules for Wavelength‐Selective Neural Networks and Fashion Image Classifications

open access: yesAdvanced Functional Materials, EarlyView.
The characteristics of a vertical floating gate heterostructure transistor device that exhibits neuromorphic potentiation under visible light illumination are investigated. Due to spectrally‐tuned absorbance properties of each thin film layer and introduction of tunneling dielectric, the device enables wavelength‐selective tuning of synaptic plasticity

Recommendations for diabetic macular edema management by retina specialists and large language model-based artificial intelligence platforms

open access: yesInternational Journal of Retina and Vitreous
Purpose To study the role of artificial intelligence (AI) in developing diabetic macular edema (DME) management recommendations by creating and comparing responses to clinicians in hypothetical AI-generated case scenarios. The study also examined whether

General features of the retinal connectome determine the computation of motion anticipation [PDF]

open access: yes, 2015
Motion anticipation allows the visual system to compensate for the slow speed of phototransduction so that a moving object can be accurately located.

Trap‐Assisted Transport and Neuromorphic Plasticity in Lead‐Free 2D Perovskites PEA2SnI4

open access: yesAdvanced Functional Materials, EarlyView.
An artificial retina built from lead‐free layered perovskite (PEA)2SnI4 converts light input into a persistent photocurrent and sums successive flashes over time. Micro/nanocrystals integrated on electrodes act as synapse‐like pixels that perform temporal integration directly in hardware. This in‐sensor preprocessing merges detection and computation on

The retinal function imager and clinical applications

open access: yesEye and Vision, 2018
Background The Retinal Function Imager (RFI) provides in vivo and noninvasive imaging of both the retinal structure and function. Review The RFI can create capillary perfusion maps, measure blood flow velocity, and determine metabolic function including ...

GABA_{B} Receptors Regulate Chick Retinal Calcium Waves [PDF]

open access: yes, 2001
Correlated spiking activity and associated Ca²⁺ waves in the developing retina are important in determining the connectivity of the visual system. Here, we show that GABA, via GABA_{B} receptors, regulates the temporal characteristics of Ca²⁺ waves ...

A minimal statistical-mechanical model for multihyperuniform patterns in avian retina

open access: yes, 2020
Birds are known for their extremely acute sense of vision. The very peculiar structural distribution of five different types of cones in the retina underlies this exquisite ability to sample light.

Carbon Contacts to Proteins Enable Robust, Biocompatible Electronic Junctions with Near‐Activation‐less Conduction Down to 10 K

open access: yesAdvanced Functional Materials, EarlyView.
A robust solid‐state protein junction with a semi‐transparent eC/Au electrode allows photoexcitation of the bacterio‐rhodopsin, bR layer, to isomerize the bR retinal. The resulting photo‐response shows the protein is functional in the solid‐state junction.
