Amyloid-beta peptide is elevated in the brains of patients with Alzheimer disease and is believed to be causative in the disease process. Amyloid-beta reduces glutamatergic transmission and inhibits synaptic plasticity, although the underlying mechanisms are unknown. We found that application of amyloid-beta promoted endocytosis of NMDA receptors in(More)
Mutations in the leucine-rich repeat kinase (LRRK2) gene cause late-onset autosomal dominant Parkinson's disease (PD) with pleiomorphic pathology. Previously, we and others found that expression of mutant LRRK2 causes neuronal degeneration in cell culture. Here we used the GAL4/UAS system to generate transgenic Drosophila expressing either wild-type human(More)
Neonatal Borna disease virus (BDV) infection of the rat brain serves as a valuable model for studying the pathogenesis of neurodevelopmental abnormalities following early brain injury. Previous experiments have demonstrated significant alterations in regional tissue content of serotonin (5-HT) in neonatally BDV-infected Lewis rats. The present study sought(More)
The benefits of money as a medium of exchange are obvious, but the historical origin of money is less clear. An existing economic model of monetary search is reproduced as an agent-based simulation and an evolutionary algorithm is used to model social learning. This approach captures the way in which different equilibria can arise, including solutions in(More)
