Retinal output changes qualitatively with every change in ambient illuminance.
Alexandra Tikidji-Hamburyan,Katja Reinhard,Hartwig Seitter,Anahit Hovhannisyan,Christopher A. Procyk,Annette E. Allen,Martin Schenk,Robert J. Lucas,Thomas Münch +8 more
TL;DR: The results suggest that the retinal code is not fixed but varies with every change of ambient luminance, which raises questions about signal processing within the retina and has implications for visual processing in higher brain areas.
Chemogenetic Activation of Melanopsin Retinal Ganglion Cells Induces Signatures of Arousal and/or Anxiety in Mice
TL;DR: Data demonstrate that mRGCs drive a light-dependent switch in behavioral motivation toward a more alert, risk-averse state, and highlight the ability of this small fraction of retinal ganglion cells to realign activity in brain regions defining widespread aspects of physiology and behavior.

Visual input to the mouse lateral posterior and posterior thalamic nuclei: photoreceptive origins and retinotopic order
TL;DR: It is shown that a subset of retinal projections to these regions derive from melanopsin‐expressing retinal ganglion cells and that, within the lateral posterior thalamus, visual responses are retinotopically ordered.

Melanopsin-Derived Visual Responses under Light Adapted Conditions in the Mouse dLGN
Katherine E. Davis,Cyril G. Eleftheriou,Annette E. Allen,Christopher A. Procyk,Robert J. Lucas +4 more
TL;DR: This article found that 25-30% of visual responsive neurons in the contralateral dLGN responded to these melanopsin-isolating steps with small increases in firing rate.
Spatial receptive fields in the retina and dorsal lateral geniculate nucleus of mice lacking rods and cones.
Christopher A. Procyk,Cyril G. Eleftheriou,Riccardo Storchi,Annette E. Allen,Nina Milosavljevic,Timothy M. Brown,Robert J. Lucas +6 more
TL;DR: The data reveal that ipRGCs can convey spatial information in advanced retinal degeneration and identify their poor temporal fidelity as the major limitation in their ability to provide information about spatial patterns under natural viewing conditions.
