SHORT COMMUNICATION Light sensitivity in a vertebrate mechanoreceptor?
نویسندگان
چکیده
Using immunohistochemistry and western blot analysis, we demonstrate that melanopsin is localised in cells around the central pore of lateral line neuromasts in the African clawed frog, Xenopus laevis. Since melanopsin is a known photoreceptor pigment with diverse functions in vertebrates, we suggest that the lateral line of Xenopus laevis, which is primarily a mechanoreceptor, might also be light sensitive. Potential functions of such photosensitivity are discussed, including its role in mediating locomotor responses following dermal illumination.

متن کاملFinite-Difference Time-Domain Simulation of Light Propagation in 2D Periodic and Quasi-Periodic Photonic Structures
Ultra-short pulse is a promising technology for achieving ultra-high data rate transmission which is required to follow the increased demand of data transport over an optical communication system. Therefore, the propagation of such type of pulses and the effects that it may suffer during its transmission through an optical waveguide has received a great deal of attention in the recent years. We...
متن کاملShort communication: Effect of light and nitrogen concentration on the growth and lipid content of marine diatom, Chaetoceros calcitrans
The effects of light intensity (µ mol m-2 s-1) and different levels of Nitrogen was made on the biomass and lipid of microalgae Chaetoceros calcitrans under laboratory conditions in the north of Iran in 2016. The pure strand of C. calcitrans with F/2 media (8 sets of 3 flasks) were placed in front of the light source at values of 80, 160, and 240 µ mol m-2 s-1. The cell count was collected in ...
متن کاملInvestigating the Possibilities of Reading Literary Texts in Light of a Sociolinguistic Perspective: Applications on the Case of Alice Walker’s Selected Short Stories
The present research tries to show how race, class, and gender and intersectionality in general, have their decisive impact on the black- American women; and how Alice Walker as a womanist, in her selected short stories, tries to show that black women in the U.S. suffer two-fold acts of oppression and discrimination, i.e. male violence affects all women in social life, irrespective of age or so...
متن کاملFrequency doubling by active in vivo motility of mechanosensory neurons in the mosquito ear
Across vertebrate and invertebrate species, nonlinear active mechanisms are employed to increase the sensitivity and acuity of hearing. In mosquitoes, the antennal hearing organs are known to use active force feedback to enhance auditory acuity to female generated sounds. This sophisticated form of signal processing involves active nonlinear events that are proposed to rely on the motile proper...
