Research Article: Dynamical Adaptation in Photoreceptors

Date Published: November 14, 2013 Publisher: Public Library of Science Author(s): Damon A. Clark, Raphael Benichou, Markus Meister, Rava Azeredo da Silveira, Lyle J. Graham Abstract: Adaptation is at the heart of sensation and nowhere is it more salient than in early visual processing. Light adaptation in photoreceptors is doubly dynamical: it depends upon the … Continue reading

Research Article: Multimodal Imaging of Photoreceptor Structure in Choroideremia

Date Published: December 9, 2016 Publisher: Public Library of Science Author(s): Lynn W. Sun, Ryan D. Johnson, Vesper Williams, Phyllis Summerfelt, Alfredo Dubra, David V. Weinberg, Kimberly E. Stepien, Gerald A. Fishman, Joseph Carroll, Rong Wen. Abstract: Choroideremia is a progressive X-linked recessive dystrophy, characterized by degeneration of the retinal pigment epithelium (RPE), choroid, … Continue reading

Research Article: Fly Photoreceptors Encode Phase Congruency

Date Published: June 23, 2016 Publisher: Public Library of Science Author(s): Uwe Friederich, Stephen A. Billings, Roger C. Hardie, Mikko Juusola, Daniel Coca, Samuel G. Solomon. Abstract: More than five decades ago it was postulated that sensory neurons detect and selectively enhance behaviourally relevant features of natural signals. Although we now know that sensory … Continue reading

Research Article: Action Spectra of Zebrafish Cone Photoreceptors

Date Published: July 5, 2013 Publisher: Public Library of Science Author(s): Duco Endeman, Lauw J. Klaassen, Maarten Kamermans, Stephan CF. Neuhauss. Abstract: Zebrafish is becoming an increasingly popular model in the field of visual neuroscience. Although the absorption spectra of its cone photopigments have been described, the cone action spectra were still unknown. In … Continue reading

Research Article: Role of Spectraplakin in Drosophila Photoreceptor Morphogenesis

Date Published: October 12, 2011 Publisher: Public Library of Science Author(s): Uyen Ngoc Mui, Christina M. Lubczyk, Sang-Chul Nam, Amit Singh. Abstract: Crumbs (Crb), a cell polarity gene, has been shown to provide a positional cue for the apical membrane domain and adherens junction during Drosophila photoreceptor morphogenesis. It has recently been found that stable … Continue reading

Research Article: Visual Coding in Locust Photoreceptors

Date Published: May 14, 2008 Publisher: Public Library of Science Author(s): Olivier Faivre, Mikko Juusola, Martin Giurfa. Abstract: Information capture by photoreceptors ultimately limits the quality of visual processing in the brain. Using conventional sharp microelectrodes, we studied how locust photoreceptors encode random (white-noise, WN) and naturalistic (1/f stimuli, NS) light patterns in vivo and … Continue reading

Research Article: A novel mechanism of cone photoreceptor adaptation

Date Published: April 12, 2017 Publisher: Public Library of Science Author(s): Marcus H. C. Howlett, Robert G. Smith, Maarten Kamermans, Jonathan Demb Abstract: An animal’s ability to survive depends on its sensory systems being able to adapt to a wide range of environmental conditions, by maximizing the information extracted and reducing the noise transmitted. The … Continue reading

Research Article: How to Protect Fly Photoreceptors

Date Published: December 28, 2006 Publisher: Public Library of Science Author(s): Rachel Jones Abstract: None Partial Text: When a nerve is injured, axons beyond the site of injury die through a process called Wallerian degeneration. This degeneration is delayed in mice that have a mutation called Wallerian degeneration slow (Wlds); these mice have three copies … Continue reading

Research Article: gdf6a Is Required for Cone Photoreceptor Subtype Differentiation and for the Actions of tbx2b in Determining Rod Versus Cone Photoreceptor Fate

Date Published: March 28, 2014 Publisher: Public Library of Science Author(s): Michèle G. DuVal, A. Phillip Oel, W. Ted Allison, Harold A. Burgess. Abstract: Functional vision restoration is within reach via stem cell therapy, but one of the largest obstacles is the derivation of colour-sensitive cone photoreceptors that are required for high-acuity daytime vision. … Continue reading

Research Article: Endothelin-2-Mediated Protection of Mutant Photoreceptors in Inherited Photoreceptor Degeneration

Date Published: February 28, 2013 Publisher: Public Library of Science Author(s): Alexa N. Bramall, Michael J. Szego, Laura R. Pacione, Inik Chang, Eduardo Diez, Pedro D’Orleans-Juste, Duncan J. Stewart, William W. Hauswirth, Masashi Yanagisawa, Roderick R. McInnes, Gianluca Tosini. Abstract: Expression of the Endothelin-2 (Edn2) mRNA is greatly increased in the photoreceptors (PRs) of mouse … Continue reading
