Prolonged Inner Retinal Photoreception Depends on the Visual Retinoid Cycle

Autor: Naheed W. Khan, Weston Pack, Kwoon Y. Wong, Xiwu Zhao

Publikováno v: The Journal of Neuroscience. 36:4209-4217

In addition to rods and cones, mammals have inner retinal photoreceptors called intrinsically photosensitive retinal ganglion cells (ipRGCs), which use the photopigment melanopsin and mediate nonimage-forming visual responses, such as pupil reflexes

Melatonin Suppression by Light in Humans Is More Sensitive Than Previously Reported

Autor: Andrew P. Chervenak, Olivia J. Walch, Kwoon Y. Wong, Benjamin Y. Li, Garen Vartanian, Petri Ala-Laurila, Weston Pack

Publikováno v: Journal of Biological Rhythms. 30:351-354

The retina drives various non-image-forming photoresponses, including circadian photoentrainment and pupil constriction. Previous investigators showed that in humans, photic suppression of the clock-controlled hormone melatonin is most sensitive to 4

Bias-free double judgment accuracy during spatial attention cueing: Performance enhancement from voluntary and involuntary attention

Autor: Stanley A. Klein, Thom Carney, Weston Pack

Publikováno v: Vision Research. 105:204-212

Recent research has demonstrated that involuntary attention improves target identification accuracy for letters using non-predictive peripheral cues, helping to resolve some of the controversy over performance enhancement from involuntary attention.

Involuntary attention enhances identification accuracy for unmasked low contrast letters using non-predictive peripheral cues

Autor: Thom Carney, Stanley A. Klein, Weston Pack

Publikováno v: Vision Research. 89:79-89

There is controversy regarding whether or not involuntary attention improves response accuracy at a cued location when the cue is non-predictive and if these cueing effects are dependent on backward masking. Various perceptual and decisional mechanis

Melatonin modulates M4-type ganglion-cell photoreceptors

Autor: Kwoon Y. Wong, Weston Pack, DiJon Hill

Publikováno v: Neuroscience. 303

In the retina, melatonin is secreted at night by rod/cone photoreceptors and serves as a dark-adaptive signal. Melatonin receptors have been found in many retinal neurons including melanopsin-containing intrinsically photosensitive retinal ganglion c

The rat retina has five types of ganglion-cell photoreceptors

Autor: Benjamin Y. Li, Andrew P. Chervenak, Aaron N. Reifler, Xiwu Zhao, Zachary D. Demertzis, Weston Pack, Brian A. Benenati, Fady S. Abufarha, Rebecca D. Wachter, Michael E. Dolikian, Kwoon Y. Wong, Benjamin S. Meyers, Andrew M. Lynch, Eden A. Dulka

Intrinsically photosensitive retinal ganglion cells (ipRGCs) are inner retinal photoreceptors that mediate non-image-forming visual functions, e.g. pupillary constriction, regulation of pineal melatonin release, and circadian photoentrainment. Five t

Bias corrected double judgment accuracy during spatial attention cueing: unmasked stimuli with non-predictive and semi-predictive cues

Autor: Thom Carney, Weston Pack, Stanley A. Klein

Publikováno v: Vision research. 105

The present experiments indicate that in a 7-AFC double judgment accuracy task with unmasked stimuli, cue location response bias can be quantified and removed, revealing unbiased improvements in response accuracy for valid cues compared to invalid cu
