    • High-sensitivity rod photoreceptor input to the blue-yellow color opponent pathway in macaque retina. 

      Chichilnisky, EJ; Field, Greg; Gauthier, JL; Greschner, M; Litke, Alan M; Marshak, DW; Rangel, C; ... (9 authors) (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 ...
    • Optimal processing of photoreceptor signals is required to maximize behavioural sensitivity. 

      Field, Greg; Okawa, Haruhisa; Miyagishima, K Joshua; Arman, A Cyrus; Hurley, James B; Sampath, Alapakkam P (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 ...
    • "Silent" NMDA Synapses Enhance Motion Sensitivity in a Mature Retinal Circuit. 

      Field, Greg; Sethuramanujam, Santhosh; Yao, Xiaoyang; deRosenroll, Geoff; Briggman, Kevin L; Awatramani, Gautam B (Neuron, 2017-12)
      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 ...
