# s-gene: epigenetic 'cis' and 'trans' memories

<< How epigenetic memory is stored and inherited is an on-going debate (..). In so-called  ‘cis  memory’, epigenetic information is proposed to be physically stored in local chromatin states that are associated, for example, with DNA methylation or histone modifications. By contrast, in  ‘trans  memory’, epigenetic information is stored in the concentration of a diffusible factor such as a transcriptional repressor. >>

# s-brain: reiterating perspectives: the Silhouette Illusion

<< If the foot touching the ground is perceived to be the left foot, the dancer appears to be spinning clockwise (if seen from above); >>

<< if it is taken to be the right foot, then she appears to be spinning counterclockwise >>

<< the way people perceive the Silhouette Illusion , a popular illusion that went viral and has received substantial online attention, has little to do with the viewers' personality, or whether they are left- or right-brained, despite the fact that the illusion is often used to test these attributes in popular e-quizzes >>

<< Niko Troje says that a reported preference for seeing the silhouette spinning clockwise rather than counter-clockwise is dependent upon the angle at which the viewer is seeing the image >>

<< Our visual system, if it has a choice, seems to prefer the view from above >>
