A Defective Crosstalk Between Neurons and Müller Glial Cells in the rd1 Retina Impairs the Regenerative Potential of Glial Stem Cells [PDF]

, 2019
Müller glial cells (MGC) are stem cells in the retina. Although their regenerative capacity is very low in mammals, the use of MGC as stem cells to regenerate photoreceptors (PHRs) during retina degenerations, such as in retinitis pigmentosa, is being ...

The number of unidentified amacrine cells in the mammalian retina [PDF]

Proceedings of the National Academy of Sciences, 1996
The three largest known populations of amacrine cells in the rabbit retina were stained with fluorescent probes in whole mounts and counted at a series of retinal eccentricities. The retinas were counterstained using a fluorescent DNA-binding molecule and the total number of nuclei in the inner nuclear layer were counted in confocal sections.

Endogenous oestrogens as neuroprotective modulators in the human retina: Evidence from transcriptomic profiling and aromatase inhibition

Journal of Neuroendocrinology, Volume 38, Issue 4, April 2026.
Single‐cell transcriptomics reveals that the human retina expresses a broad repertoire of steroid hormone biosynthesis and estrogen signalling genes. Functional validation in retinal explants shows that local estrogen synthesis is neuroprotective, preventing photoreceptor death and limiting microglial activation. Abstract Steroid hormones, particularly

Plasmon‐Doped Organic Heterojunction Optoelectronic Synapses for Near‐Infrared Visual Memory and Neuromorphic Computing

Aggregate, Volume 7, Issue 3, March 2026.
A near‐infrared organic photonic synapse with gold nanorods enhances light absorption and synaptic plasticity. When integrated into CNN and CSNN models, the device achieved accuracies of 98.57% and 92.01% on MNIST digit and dynamic gesture recognition tasks, respectively, demonstrating strong potential for intelligent vision and low‐power neuromorphic ...

The Effects of Neurosteroids, such as Pregnenolone Sulfate and its receptor, TrpM3 in the Retina. [PDF]

, 2019
Pregnenolone sulfate (PregS) is the precursor to all steroid hormones and is produced in neurons in an activity dependent manner. Studies have shown that PregS production is upregulated during certain critical periods of development, such as in the first

Imprecision in Vision: Lessons From Neural Circuits in the Fly

BioEssays, Volume 48, Issue 3, March 2026.
Visual systems are considered regular, retinotopic structures. Here, we summarize findings, including evidence from recent connectomes, that demonstrate cellular and synaptic heterogeneity in the Drosophila visual system —from regional specialization and stochastic photoreceptor patterns to heterogeneous synaptic connectivity.

Optoelectronic synapses based on two‐dimensional transition metal dichalcogenides for neuromorphic applications

InfoScience, Volume 3, Issue 1, March 2026.
This review first introduces the fundamental concepts of artificial synapses and synaptic plasticity, then discusses the device structures and operation mechanisms of optoelectronic synapses based on two‐dimensional transition metal dichalcogenides, highlights their applications in neuromorphic vision systems and computing, and concludes with key ...

AII amacrine cells in the primate fovea contribute to photopic vision

Scientific Reports, 2018
The AII amacrine cell is known as a key interneuron in the scotopic (night-vision) pathway in the retina. Under scotopic conditions, rod signals are transmitted via rod bipolar cells to AII amacrine cells, which split the rod signal into the OFF (via ...

A Unified Quantitative Model of Vision and Audition [PDF]

, 2014
We have put forwards a unified quantitative framework of vision and audition, based on existing data and theories. According to this model, the retina is a feedforward network self-adaptive to inputs in a specific period.
