Anatomical identification of extracellularly recorded cells in large-scale multielectrode recordings.
(J Neurosci, 2015-03-18)
This study combines for the first time two major approaches to understanding the function
and structure of neural circuits: large-scale multielectrode recordings, and confocal
imaging of labeled neurons. To achieve this ...
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, ...
High-sensitivity rod photoreceptor input to the blue-yellow color opponent pathway in macaque retina.
(Nat Neurosci, 2009-09)
Small bistratified cells (SBCs) in the primate retina carry a major blue-yellow opponent
signal to the brain. We found that SBCs also carry signals from rod photoreceptors,
with the same sign as S cone input. SBCs exhibited ...
Retinal representation of the elementary visual signal.
(Neuron, 2014-01)
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 ...
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 ...
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 ...
Functional connectivity in the retina at the resolution of photoreceptors.
(Nature, 2010-10)
To understand a neural circuit requires knowledge of its connectivity. Here we report
measurements of functional connectivity between the input and ouput layers of the
macaque retina at single-cell resolution and the implications ...
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 ...
