    • A polyaxonal amacrine cell population in the primate retina. 

      Greschner, Martin; Field, Greg D; Li, Peter H; Schiff, Max L; Gauthier, Jeffrey L; Ahn, Daniel; Sher, Alexander; ... (9 authors) (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, ...

    • Anatomical identification of extracellularly recorded cells in large-scale multielectrode recordings. 

      Li, Peter H; Gauthier, Jeffrey L; Schiff, Max; Sher, Alexander; Ahn, Daniel; Field, Greg D; Greschner, Martin; ... (10 authors) (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 ...

    • Identification of a Retinal Circuit for Recurrent Suppression Using Indirect Electrical Imaging. 

      Greschner, Martin; Heitman, Alexander K; Field, Greg D; Li, Peter H; Ahn, Daniel; Sher, Alexander; Litke, Alan M; ... (8 authors) (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 ...

    • Pathway-specific asymmetries between ON and OFF visual signals 

      Ravi, Sneha; Ahn, Daniel; Greschner, Martin; Chichilnisky, EJ; Field, Greg
      <jats:title>Abstract</jats:title><jats:p>Visual processing is largely organized into ON and OFF pathways that signal stimulus increments and decrements, respectively. These pathways exhibit natural pairings based on morphological ...

    • Pathway-Specific Asymmetries between ON and OFF Visual Signals. 

      Ravi, Sneha; Ahn, Daniel; Greschner, Martin; Chichilnisky, EJ; Field, Greg D (The Journal of neuroscience : the official journal of the Society for Neuroscience, 2018-11)
      Visual processing is largely organized into ON and OFF pathways that signal stimulus increments and decrements, respectively. These pathways exhibit natural pairings based on morphological and physiological similarities, ...

    • Retinal representation of the elementary visual signal. 

      Li, Peter H; Field, Greg D; Greschner, Martin; Ahn, Daniel; Gunning, Deborah E; Mathieson, Keith; Sher, Alexander; ... (9 authors) (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 ...
