A polyaxonal amacrine cell population in the primate retina.
(The Journal of neuroscience : the official journal of the Society for Neuroscience, 2014-03)
Amacrine cells are the most diverse and least understood cell class in the retina. Polyaxonal amacrine cells (PACs) are a unique subset identified by multiple long axonal processes. To explore their functional properties, ...
Efficient coding of spatial information in the primate retina.
(The Journal of neuroscience : the official journal of the Society for Neuroscience, 2012-11)
Sensory neurons have been hypothesized to efficiently encode signals from the natural environment subject to resource constraints. The predictions of this efficient coding hypothesis regarding the spatial filtering properties ...
Retinal Representation of the Elementary Visual Signal
Optimal processing of photoreceptor signals is required to maximize behavioural sensitivity.
(The Journal of physiology, 2010-06)
The sensitivity of receptor cells places a fundamental limit upon the sensitivity of sensory systems. For example, the signal-to-noise ratio of sensory receptors has been suggested to limit absolute thresholds in the visual ...
Gap Junctions Contribute to Differential Light Adaptation across Direction-Selective Retinal Ganglion Cells.
Direction-selective ganglion cells (DSGCs) deliver signals from the retina to multiple brain areas to indicate the presence and direction of motion. Delivering reliable signals in response to motion is critical across light ...
"Silent" NMDA Synapses Enhance Motion Sensitivity in a Mature Retinal Circuit.
Retinal direction-selective ganglion cells (DSGCs) have the remarkable ability to encode motion over a wide range of contrasts, relying on well-coordinated excitation and inhibition (E/I). E/I is orchestrated by a diverse ...
Retinal representation of the elementary visual signal.
The propagation of visual signals from individual cone photoreceptors through parallel neural circuits was examined in the primate retina. Targeted stimulation of individual cones was combined with simultaneous recording ...
Monte Carlo methods for localization of cones given multielectrode retinal ganglion cell recordings.
(Network (Bristol, England), 2013-01)
It has recently become possible to identify cone photoreceptors in primate retina from multi-electrode recordings of ganglion cell spiking driven by visual stimuli of sufficiently high spatial resolution. In this paper we ...
Correlated firing among major ganglion cell types in primate retina.
(The Journal of physiology, 2011-01)
Retinal ganglion cells exhibit substantial correlated firing: a tendency to fire nearly synchronously at rates different from those expected by chance. These correlations suggest that network interactions significantly shape ...
Nogo receptor 1 is expressed by nearly all retinal ganglion cells.
(PloS one, 2018-01)
A variety of conditions ranging from glaucoma to blunt force trauma lead to optic nerve atrophy. Identifying signaling pathways for stimulating axon growth in the optic nerve may lead to treatments for these pathologies. ...
