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 …

Notable Paper: Functional Activation of Glutamate Ionotropic Receptors in the Human Peripheral Retina

This paper by Clairton F. de Souza, Michael Kalloniatis, Philip J. Polkinghorne, Charles N.J. McGhee, Monica L. Acosta examines glutamate receptors and their functional activation in the human retina. Glutamate is the major excitatory neurotransmitter in the vertebrate retina and those excitatory neurons in the retina rely on a host of receptors to detect glutamate and …
