Kebab Illusion

A Variation of Kebab Illusion Here, I show you new illusion, Kebab Illusion. This illusion is a GIF animation which is composed of three frames. Time-line of Kebab Illusion You will percieve the illusory motion in the line. At the same time, the pre-cue presented at the Frame 1 may shift in the direction of the motion. A Variation of Kebab Illusion Real and Percieved Plesase refer to the following paper and Prof Kitaoka's Web Page for detail.

[Paper] Evolutionary differentiation of androgen receptor is responsible for sexual characteristic development in a teleost fish

Teleost fishes exhibit complex sexual characteristics in response to androgens, such as fin enlargement and courtship display. However, the molecular mechanisms underlying their evolutionary acquisition remain largely unknown. To address this question, we analyse medaka (Oryzias latipes) mutants deficient in teleost-specific androgen receptor ohnologs (ara and arb). We discovered that neither ar ohnolog was required for spermatogenesis, whilst they appear to be functionally redundant for the courtship display in males. However, both were required for reproductive success: ara for tooth enlargement and the reproductive behaviour eliciting female receptivity, arb for male-specific fin morphogenesis and sexual motivation. We further showed that differences between the two ar ohnologs in their transcription, cellular localisation of their encoded proteins, and their downstream genetic programmes could be responsible for the phenotypic diversity between the ara and arb mutants. These findin
