Mapping nonlinear receptive field structure in primate retina at single cone resolution.
The function of a neural circuit is shaped by the computations performed by its interneurons, which in many cases are not easily accessible to experimental investigation. Here, we elucidate the transformation of visual signals ...
Probing Computation in the Primate Visual System at Single-Cone Resolution.
(Annual review of neuroscience, 2019-03-11)
Daylight vision begins when light activates cone photoreceptors in the retina, creating spatial patterns of neural activity. These cone signals are then combined and processed in downstream neural circuits, ultimately producing ...
Temporal resolution of single photon responses in primate rod photoreceptors and limits imposed by cellular noise.
(Journal of neurophysiology, 2018-11-28)
Sensory receptor noise corrupts sensory signals, contributing to imperfect perception and dictating central processing strategies. For example, noise in rod phototransduction limits our ability to detect light and minimizing ...
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
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 ...
Identification of a Retinal Circuit for Recurrent Suppression Using Indirect Electrical Imaging.
(Current biology : CB, 2016-08)
Understanding the function of modulatory interneuron networks is a major challenge, because such networks typically operate over long spatial scales and involve many neurons of different types. Here, we use an indirect electrical ...
