Light activation of the dopaminergic system occurs after eye-opening in the mouse retina
Frontiers in Ophthalmology, 2023 The neuromodulator dopamine plays a significant role in light adaptation, eye growth, and modulation of neuronal circuitry in the retina. Dopaminergic amacrine cells in the adult retina release dopamine in response to light stimulation, however, the ...

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

Sphingolipids as emerging mediators in retina degeneration [PDF]
, 2019 The sphingolipids ceramide (Cer), sphingosine-1-phosphate (S1P), sphingosine (Sph), and ceramide-1-phosphate (C1P) are key signaling molecules that regulate major cellular functions.

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 ...

The fountain amacrine cells of the rabbit retina
Visual Neuroscience, 1999 We have characterized a distinctive type of bistratified amacrine cell in the rabbit retina at both the single cell and population levels. These cells correspond to the “fountain” amacrine cells recently identified by MacNeil and Masland (1998). The fountain cells can be distinguished in superfused retinal wholemounts labeled with nuclear dyes ...

Conservation of Neuron‐Astrocyte Correlated Activity in Developing Sensory Pathways
Glia, Volume 74, Issue 5, May 2026.Astrocytes and neurons in the superior colliculus exhibit spatiotemporal correlated activity before eye opening. Each neuronal wave is followed by a calcium wave in astrocytes. Spillover of glutamate activates mGluR5 and mGluR3 in astrocytes. ABSTRACT Neurons in developing sensory organs exhibit prolonged burst firing before the onset of sensory ...

Growing Critical: Self-Organized Criticality in a Developing Neural System [PDF]
, 2018 Experiments in various neural systems found avalanches: bursts of activity with characteristics typical for critical dynamics. A possible explanation for their occurrence is an underlying network that self-organizes into a critical state.

Genes to Cells, Volume 31, Issue 3, May 2026.The effects of intraocular administration of neutralizing antibodies against VEGFA, ANG‐2, or bispecific to these two factors on pathological findings were examined in the oxygen‐induced retinopathy (OIR) mouse model. The antibody to VEGFA or ANG‐2 attenuated oxygen‐induced neovascularization and inflammation, and the bispecific antibody more ...

Crossover inhibition in the retina: circuitry that compensates for nonlinear rectifying synaptic transmission [PDF]
, 2009 In the mammalian retina, complementary ON and OFF visual streams are formed at the bipolar cell dendrites, then carried to amacrine and ganglion cells via nonlinear excitatory synapses from bipolar cells. Bipolar, amacrine and ganglion cells also receive

Increased phosphorylation of Cx36 gap junctions in the AII amacrine cells of RD retina
Frontiers in Cellular Neuroscience, 2015 Retinal degeneration (RD) encompasses a family of diseases that lead to photoreceptor death and visual impairment. Visual decline due to photoreceptor cell loss is further compromised by emerging spontaneous hyperactivity in inner retinal cells.
