Amacrine Cells in Scotopic Vision

Ophthalmic Research, 1984
Signals from rod bipolar cells of cat retina are processed by a variety of rod amacrine cells before finally arriving at ganglion cells. Three of these rod amacrine cells (AII, A13, and A17 ) have been studied at the physiological and anatomical levels; the results suggest that each carries out a unique visual function: AII cells appear to quicken the ...

Seizure-related gene 6 (Sez-6) in amacrine cells of the rodent retina and the consequence of gene deletion. [PDF]

PLoS ONE, 2009
BackgroundSeizure-related gene 6 (Sez-6) is expressed in neurons of the mouse brain, retina and spinal cord. In the cortex, Sez-6 plays a role in specifying dendritic branching patterns and excitatory synapse numbers during development.Methodology ...

Pten regulates endocytic trafficking of cell adhesion and Wnt signaling molecules to pattern the retina

Cell Reports
Summary: The retina is exquisitely patterned, with neuronal somata positioned at regular intervals to completely sample the visual field. Here, we show that phosphatase and tensin homolog (Pten) controls starburst amacrine cell spacing by modulating ...

Connexin30.2: in vitro interaction with connexin36 in HeLa cells and expression in AII amacrine cells and intrinsically photosensitive ganglion cells in the mouse retina

Frontiers in Molecular Neuroscience, 2016
Electrical coupling via gap junctions is an abundant phenomenon in the mammalian retina and occurs in all major cell types. Gap junction channels are assembled from different connexin subunits, and the connexin composition of the channel confers specific

Retinal Processing: Insights from Mathematical Modelling

Journal of Imaging, 2022
The retina is the entrance of the visual system. Although based on common biophysical principles, the dynamics of retinal neurons are quite different from their cortical counterparts, raising interesting problems for modellers.

Second-order neural core for bioinspired focal-plane dynamic image processing in CMOS [PDF]

, 2004
Based on studies of the mammalian retina, a bioinspired model for mixed-signal array processing has been implemented on silicon. This model mimics the way in which images are processed at the front-end of natural visual pathways, by means of programmable

Response Properties of a Newly Identified Tristratified Narrow Field Amacrine Cell in the Mouse Retina. [PDF]

PLoS ONE, 2015
Amacrine cells were targeted for whole cell recording using two-photon fluorescence microscopy in a transgenic mouse line in which the promoter for dopamine receptor 2 drove expression of green fluorescent protein in a narrow field tristratified amacrine

Engineered Living Systems With Self‐Organizing Neural Networks: From Anatomy to Behavior and Gene Expression

Advanced Science, EarlyView.
Ectodermal tissue excised from Xenopus embryos self‐organizes into a three‐dimensional mucociliary organoid. Here, we generate a neural variant, termed neurobot, by implanting neural precursor cells. Neurobots develop mature neurons, adopt distinct morphologies, exhibit more complex motility, and respond differentially to neuroactive compounds. Imaging

Glycinergic transmission in the mammalian retina

Frontiers in Molecular Neuroscience, 2009
Glycine and γ-aminobutyric acid (GABA) are the major inhibitory neurotransmitters in the retina. Approximately half of the amacrine cells release glycine at their synapses with bipolar, other amacrine, and ganglion cells. Glycinergic amacrine cells

Organization of the dorsal lateral geniculate nucleus in the mouse [PDF]

, 2017
The dorsal lateral geniculate nucleus (dLGN) of the thalamus is the principal conduit for visual information from retina to visual cortex. Viewed initially as a simple relay, recent studies in the mouse reveal far greater complexity in the way input from
