Directionally selective calcium signals in dendrites of starburst amacrine cells
Dendritic calcium signals, but not somatic membrane voltage, are directionally selective for stimuli that move centrifugally from the cell soma, demonstrating that direction selectivity is computed locally in dendritic branches at a stage before ganglion cells.
The functional diversity of retinal ganglion cells in the mouse
It is shown that the mouse retina harbours substantially more than 30 functional output channels, which include all known and several new ganglion cell types, as verified by genetic and anatomical criteria.
Retinal bipolar cells: elementary building blocks of vision
Retinal bipolar cells are the first 'projection neurons' of the vertebrate visual system and represent elementary 'building blocks' from which the microcircuits of the inner retina derive a feature-oriented description of the visual world.
Immunocytochemical identification of cone bipolar cells in the rat retina
In addition to the rod bipolar cell, nine different putative cone bipolar cell types were distinguished according to the position of their somata in the inner nuclear layer and the branching pattern and stratification level of their axon terminals in theinner plexiform layer.
A Dendrite-Autonomous Mechanism for Direction Selectivity in Retinal Starburst Amacrine Cells
It is concluded that dendritic DS in SACs can be computed by the dendrites themselves, relying on voltage-gated channels and a dendrite voltage gradient, which provides the spatial asymmetry necessary for direction discrimination.
Functional Stability of Retinal Ganglion Cells after Degeneration-Induced Changes in Synaptic Input
It is found that strong rhythmic synaptic input drives ongoing oscillatory spike activity in both ON and OFF RGCs at a fundamental “beating” frequency of ∼10 Hz, which maintains their characteristic dendritic stratification, intrinsic firing properties, and balance of synaptic excitation and inhibition during degeneration-induced retinal activity.
The Primordial, Blue-Cone Color System of the Mouse Retina
The blue-cone bipolar cells of the mouse retina and their cone selectivity are closely similar to primate blue- cone bipolars, and it is suggested that they both represent the phylogenetically ancient color system of the mammalian retina.
Seeing Things in Motion: Models, Circuits, and Mechanisms
Light-evoked responses of bipolar cells in a mammalian retina.
Functional properties of the axon terminal system-notably synaptic feedback from amacrine cells-play an important role in defining the response properties of mammalian bipolar cells.
Functional Fluorescent Ca2+ Indicator Proteins in Transgenic Mice under TET Control
It is found that stimuli known to increase intracellular calcium concentration (somatically triggered action potentials and synaptic and sensory stimulation) can cause substantial and rapid changes in FCIP fluorescence of inverse pericam and camgaroo-2.
