Neural Development, 2017 Background Amacrine interneurons that modulate synaptic plasticity between bipolar and ganglion cells constitute the most diverse cell type in the retina. Most are inhibitory neurons using either GABA or glycine as neurotransmitters.

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

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 ...

Local processing in neurites of VGluT3- expressing amacrine cells differentially organizes visual information [PDF]
, 2017 Neurons receive synaptic inputs on extensive neurite arbors. How information is organized across arbors and how local processing in neurites contributes to circuit function is mostly unknown.

Ganglion cell and displaced amacrine cell density distribution in the retina of the howler monkey (Alouatta caraya). [PDF]
PLoS ONE, 2014 Unlike all other New World (platyrrine) monkeys, both male and female howler monkeys (Alouatta sp.) are obligatory trichromats. In all other platyrrines, only females can be trichromats, while males are always dichromats, as determined by multiple ...

Regional Variation of Gap Junctional Connections in the Mammalian Inner Retina
Cells, 2021 The retinas of many species show regional specialisations that are evident in the differences in the processing of visual input from different parts of the visual field.

The Projective Field of a Retinal Amacrine Cell [PDF]
Journal of Neuroscience, 2011 In sensory systems, neurons are generally characterized by their receptive field, namely the sensitivity to activity patterns at the input of the circuit. To assess the role of the neuron in the system, one must also know its projective field, namely the spatiotemporal effects the neuron exerts on all of the outputs of the circuit.

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

Functional Compartmentalization within Starburst Amacrine Cell Dendrites in the Retina
Cell Reports, 2018 Summary: Dendrites in many neurons actively compute information. In retinal starburst amacrine cells, transformations from synaptic input to output occur within individual dendrites and mediate direction selectivity, but directional signal fidelity at ...

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
