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 ...
