There is growing interest in studying the role of connectivity patterns in brain functions. In recent years, functional brain networks were found to exhibit small-world properties during different brain states. In previous studies, time-independent networks were recovered from long time periods of brain activity. In this paper, we propose an approach, the(More)
Estrogens are powerful modulators of neuronal physiology and in humans may affect a broad range of functions, including reproductive, emotional, and cognitive behaviors. We studied the contribution of estrogen receptors (ERs) in modulation of emotional processes and analyzed the effects of deleting ERalpha or ERbeta in mice. Behavior consistent with(More)
Functional effects of prenatal cocaine exposure may be mediated in part by changes in catecholaminergic development. The present study examined whether cocaine administration influenced fetal brain activity of tyrosine hydroxylase (TH), the rate-limiting enzyme in catecholamine biosynthesis. Subcutaneous (s.c.) injection of pregnant rats with 40 mg/kg of(More)
OBJECTIVES To determine the risk factors and incidence of cerebral infarction associated with POEMS (polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes) syndrome. METHODS The Mayo Clinic dysproteinemia database was queried to identify patients with coded diagnosis of POEMS syndrome. Patients with cerebral infarction,(More)
