TLDR
In this article, the authors used two-photon glutamate imaging to measure synaptic release and reveal that direction selectivity along all four directions arises earlier than expected at bipolar cell outputs.About:

Origins of direction selectivity in the primate retina
TL;DR: In this article , the authors combined functional recordings of light-evoked responses and connectomic reconstruction to identify diverse direction-selective cell types in the macaque monkey retina with distinctive physiological properties and synaptic motifs.

Center-surround interactions underlie bipolar cell motion sensitivity in the mouse retina
Sarah Strauss,Maria M. Korympidou,Yanli Ran,Katrin Franke,Timm Schubert,Tom Baden,Philipp Berens,Thomas Euler,Anna Vlasits +8 more
TL;DR: In this article , the authors studied the representation of motion in mouse retinal bipolar cells and found that some bipolar cells are radially direction selective, preferring the origin of small object motion trajectories.
Journal ArticleDOI
Distinct inhibitory pathways control velocity and directional tuning in the mouse retina
TL;DR: In this article , the authors investigated two circuits responsible for encoding different aspects of image motion: ON and ON-OFF direction-selective ganglion cells (DSGCs) and showed that distinct inhibitory pathways independently control tuning for motion velocity and motion direction in these two cell types.
Journal ArticleDOI
Classical center-surround receptive fields facilitate novel object detection in retinal bipolar cells
TL;DR: In this paper , the authors found that bipolar glutamate release emphasizes objects that emerge in the receptive field (RF) during continuous motion, and that the alteration in signal dynamics induced by novel objects was more pronounced than edge enhancement.
Journal ArticleDOI
Diurnal changes in the efficiency of information transmission at a sensory synapse
TL;DR: In this paper , the authors investigated how neuromodulation alters the amount of information transmitted through the circuit and demonstrated that contrast sensitivity peaks in the afternoon accompanied by a four-fold increase in the average Shannon information transmitted from an active zone.

Populations of wide-field amacrine cells in the mouse retina.
TL;DR: Wide‐field amacrine cells in the mouse are surveyed, using a large series of retinas from a transgenic strain that expresses the green fluorescent protein (GFP) in isolated retinal cells, and it seems likely that their physiological functions represent variations on a single organizational plan.
Journal ArticleDOI
Horizontal cell feedback without cone type-selective inhibition mediates ‘red-green’ color opponency in midget ganglion cells of the primate retina
TL;DR: Red–green opponency appears to arise via outer retinal horizontal cell feedback that is not cone type selective without recourse to any inner retinal L versus M cone inhibitory pathways, as well as enrichment of retinal pH-buffering capacity.

Synaptic Properties of SOM- and CCK-Expressing Cells in Dentate Gyrus Interneuron Networks
Shakuntala Savanthrapadian,Thomas Meyer,Claudio Elgueta,Sam A. Booker,Imre Vida,Marlene Bartos +5 more
TL;DR: Dendritic inhibition seems to play an important role in determining the activity pattern of GABAergic interneuron populations and thereby the flow of information through the DG circuitry.
Journal ArticleDOI
Analogous Convergence of Sustained and Transient Inputs in Parallel On and Off Pathways for Retinal Motion Computation
TL;DR: In this paper, the authors reconstructed On SACs and On bipolar cells (BCs) from serial electron microscopic images of a mouse retina and found evidence that sustained and transient On BC types are wired to On sAC dendrites at different distances from the SAC soma, mirroring their previous wiring diagram for the Off BC-SAC circuit.

Structure and function of a neocortical synapse.
TL;DR: In this article, a linear relationship between synapse size and strength was found, providing the missing link in assigning physiological weights to synapses reconstructed from electron microscopy, and revealed that neocortical synapses may have greater computational capacity than thought.
