Extreme Compartmentalization in a Drosophila Amacrine Cell [PDF]

Current Biology, 2019
A neuron is conventionally regarded as a single processing unit. It receives input from one or several presynaptic cells, transforms these signals, and transmits one output signal to its postsynaptic partners. Exceptions exist: amacrine cells in the mammalian retina [1-3] or interneurons in the locust mesothoracic ganglion [4] are thought to represent ...

Monoaminergic modulation of photoreception in ascidian:evidence for a proto-hypothalamo-retinal territory [PDF]

, 2012
Background : The retina of craniates/vertebrates has been proposed to derive from a photoreceptor prosencephalic territory in ancestral chordates, but the evolutionary origin of the different cell types making the retina is disputed.

Ceramide is a Mediator of Apoptosis in Retina Photoreceptors [PDF]

, 2006
PURPOSE. The precise mechanisms involved in photoreceptor apoptosis are still unclear. We here investigated the role of ceramide, a sphingolipid precursor that induces apoptosis upon cellular stress, in activating this death in photoreceptors.

Human iPSC differentiation to retinal organoids in response to IGF1 and BMP4 activation is line- and method-dependent [PDF]

, 2020
Induced pluripotent stem cell (iPSC)‐derived retinal organoids provide a platform to study human retinogenesis, disease modeling, and compound screening.

Classification of Mouse Retinal Bipolar Cells: Type-Specific Connectivity with Special Reference to Rod-Driven AII Amacrine Pathways

Frontiers in Neuroanatomy, 2017
We confirmed the classification of 15 morphological types of mouse bipolar cells by serial section transmission electron microscopy and characterized each type by identifying chemical synapses and gap junctions at axon terminals.

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 ...

Special nuclear layer contacts between starburst amacrine cells in the mouse retina

Frontiers in Ophthalmology, 2023
Starburst amacrine cells are a prominent neuron type in the mammalian retina that has been well-studied for its role in direction-selective information processing.

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

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

Losses of immunoreactive parvalbumin amacrine and immunoreactive alphaprotein kinase C bipolar cells caused by methylmercury chloride intoxication in the retina of the tropical fish Hoplias malabaricus

Brazilian Journal of Medical and Biological Research, 2006
To quantify the effects of methylmercury (MeHg) on amacrine and on ON-bipolar cells in the retina, experiments were performed in MeHg-exposed groups of adult trahiras (Hoplias malabaricus) at two dose levels (2 and 6 µg/g, ip).
