This paper by Christopher W. Yee, Abduqodir H. Toychiev and Botir T. Sagdullaev examines the role that neural oscillations play in normal and pathological states. In a neurodegenerative model of retinitis pigmentosa, the authors examined the activity of neural networks in the rd1 mouse model and compared that activity to the wild type. The authors …

Giant Squid Eyes
A recent paper by Dan-Eric Nilsson, Eric J. Warrant, Sönke Johnsen, Roger Hanlon and Nadav Shashar reports on the eyes of some of the most mysterious of creatures, Architeuthis and Mesonychoteuthis, the giant and colossal deep sea squid respectively. We here at Webvision love all things retina and would deeply love to get our hands …
Great Review: Defective Trafficking of Rhodopsin and Its Role In Retinal Degenerations
This is a great review paper on the role of rhodopsin trafficking and its influence on retinal degenerative disease by TJ Hollingsworth and Alecia Gross. Rhodopsin delocalization in rod photoreceptors has been recognized for some time as one of the first indications of retinal photoreceptor cell stress in retinal degenerative diseases, so I was intrigued …

Iris Tumor Goniometer
Iris tumors are fairly common and have been featured here on Webvision before. Most “tumors” are actually cysts or benign nevi, but malignant melanomas also can occur. Fortunately, most of them are restricted in size and they do not proliferate, but are monitored through slit lamp examination like these images. Ultrasound monitoring also is used …
Jumping Spiders Use Image Defocusing For Depth Perception
A study out in today’s Science Magazine by Takashi Nagata, Mitsumasa Koyanagi, Hisao Tsukamoto, Shinjiro Saeki, Kunio Isono, Yoshinori Shichida, Fumio Tokunaga, Michiyo Kinoshita, Kentaro Arikawa and Akihisa Terakita proposes that jumping spiders at least, use image defocusing to provide depth perception. Jumping spiders (Salticidae) are the largest family of spiders and have perhaps the best visual …
