- Functional connectivity in the retina at the resolution of photoreceptorsGreg D Field
Systems Neurobiology Laboratories, Salk Institute for Biological Studies, La Jolla, California 92037, USA
Nature 467:673-7. 2010..These measurements reveal computations in a neural circuit at the elementary resolution of individual neurons...
- Retinal processing near absolute threshold: from behavior to mechanismGreg D Field
Department of Physiology and Biophysics, University of Washington, Seattle, Washington 98195, USA
Annu Rev Physiol 67:491-514. 2005..We summarize what is known about how these constraints are met and identify some of the outstanding open issues...
- High-sensitivity rod photoreceptor input to the blue-yellow color opponent pathway in macaque retinaGreg D Field
Salk Institute for Biological Studies, La Jolla, California, USA
Nat Neurosci 12:1159-64. 2009..Third, rod input to SBCs may be the substrate for behavioral biases toward perception of blue at mesopic light levels...
- Spatial properties and functional organization of small bistratified ganglion cells in primate retinaGreg D Field
Salk Institute for Biological Studies, La Jolla, California 92037, USA
J Neurosci 27:13261-72. 2007..Thus, despite their distinctive morphology and chromatic properties, SBCs exhibit two features of other retinal ganglion cell types: center-surround antagonism and regular mosaic sampling of visual space...
- Correlated firing among major ganglion cell types in primate retinaMartin Greschner
Systems Neurobiology Laboratory, Salk Institute for Biological Studies, La Jolla, CA, USA
J Physiol 589:75-86. 2011..Collectively, these results provide an overview of correlated firing across cell types in the primate retina, and constraints on the underlying mechanisms...
- The structure of multi-neuron firing patterns in primate retinaJonathon Shlens
Department of Systems Neurobiology, The Salk Institute, La Jolla, California 92037, USA
J Neurosci 26:8254-66. 2006..This approach provides a way to define limits on the complexity of network interactions and thus may be relevant for probing the function of many neural circuits...
- The structure of large-scale synchronized firing in primate retinaJonathon Shlens
The Salk Institute, La Jolla, California 92037, USA
J Neurosci 29:5022-31. 2009..In sum, large-scale synchronized firing in the entire population of ON-parasol cells appears to reflect simple neighbor interactions, rather than a unique visual signal or a highly redundant coding scheme...
- Receptive fields in primate retina are coordinated to sample visual space more uniformlyJeffrey L Gauthier
Salk Institute for Biological Studies, La Jolla, California, United States of America
PLoS Biol 7:e1000063. 2009..These results show that the primate retina encodes light with an exquisitely coordinated array of RF shapes, illustrating a higher degree of functional precision in the neural circuitry than previously appreciated...

- Mechanisms regulating variability of the single photon responses of mammalian rod photoreceptorsGreg D Field
Department of Physiology and Biophysics, University of Washington, 98195, Seattle, WA, USA
Neuron 35:733-47. 2002..The measured responses, however, could be explained by multistep shutoff of rhodopsin or a combination of multistep shutoff and saturation...
- Optimal processing of photoreceptor signals is required to maximize behavioural sensitivityHaruhisa Okawa
Department of Physiology and Biophysics, University of Southern California, USC Keck School of Medicine, 1501 San Pablo St, ZNI 435, Los Angeles, CA 90089, USA
J Physiol 588:1947-60. 2010..Thus, it is critical for retinal processing to be optimally tuned near absolute threshold; otherwise the visual system fails to utilize fully the signals present in the rods...
