Fearful symmetry

Fearful symmetry: subversion of asymmetric division in cancer development and progression.

Asymmetric division is an evolutionarily conserved process that generates daughter cells with different fates through the unequal partitioning of fate determinants. While asymmetric division is critically important in generating diversity during development, its dysregulation can also promote oncogenesis. In particular, signals that shift the normal balance of symmetric and asymmetric division ...

Fearless-Evolution on Boolean Landscapes: Boolean Phase Portraits Reveal a New Navigation Strategy Based on Fearful Symmetry

We present two important developments for understanding nk Boolean landscapes: First, a discrete analogue to the continuous phase portrait for analyzing Boolean landscapes and, second, an evolutionary alternative to mutation and recombination. Applications include evolution in biological systems, social networks, electrical flow on power grids, business organizations. The Curie Principle states...

Human amygdala responses to fearful eyes.

Fearful facial expressions evoke increased neural responses in human amygdala. We used event-related fMRI to investigate whether eye or mouth components of a fearful face are critical in evoking this increased amygdala activity. In addition to prototypical fearful (FF) and neutral (NN) faces, subjects viewed two types of chimerical face: fearful eyes combined with a neutral mouth (FN), and neut...
