Activity patterns of neural population are constrained by underlying biological mechanisms. These patterns are characterized not only by individual activity rates and pairwise correlations but also by statistical dependencies among groups of neurons larger than two, known as higher-order interactions (HOIs). While HOIs are ubiquitous in neural activity, primary characteristics of HOIs remain un...

The discovery of the therapeutic properties of certain steroids has recently given rise to interesting chemical and pharmacological problems. The remarkable antiphlogistic activities of halogenated derivatives of hydrocortisone, and the disappearance of secondary effects obtained by the A1-diene derivatives of cortisone, have suggested the synthesis of a steroid which joins the two chemical cha...

Early, lesion-based models of language processing suggested that semantic and phonological processes are associated with distinct temporal and parietal regions respectively, with frontal areas more indirectly involved. Contemporary spatial brain mapping techniques have not supported such clear-cut segregation, with strong evidence of activation in left temporal areas by both processes and dispu...
