![]() Seizures with similar pathways tended to occur closer together in time, and a simple model suggested that seizure pathways change on circadian and/or slower timescales in the majority of patients. In all patients, we found variability in seizure paths through the space of possible network dynamics. We quantitatively compared within-patient seizure network evolutions using intracranial electroencephalographic (iEEG) recordings of over 500 seizures from 31 patients with focal epilepsy (mean 16.5 seizures per patient). ![]() ![]() Although epilepsy is a dynamic disorder characterized by pathological fluctuations in brain state, surprisingly little is known about whether and how seizures vary in the same patient. Balancing, propinquity based on coresidence, and homophily regarding nonracial categories (e.g., students from “elite” backgrounds or those from particular states) all influence the tie formation process more than does racial homophily.Personalized medicine requires that treatments adapt to not only the patient but also changing factors within each individual. Then, they put the importance of racial homophily further into perspective by comparing its effects to those of other mechanisms of tie formation. ![]() They first show that racial homogeneity results not only from racial homophily proper but also from homophily among coethnics of the same racial background and from balancing mechanisms such as the tendency to reciprocate friendships or to befriend the friends of friends, which both amplify the homogeneity effects of homophily. The authors unpack racial homogeneity using a theoretical framework that distinguishes between various tie formation mechanisms and their effects on the racial composition of networks, exponential random graph modeling that can disentangle these mechanisms empirically, and a rich new data set based on the Facebook pages of a cohort of college students. social networks is their high degree of racial homogeneity, which is often attributed to racial homophily-the preference for associating with individuals of the same racial background. ![]()
