Morphine sensitization and state-dependent learning in mice
In the present study, the effects of morphine sensitization on morphine-induced impairment of memory formation and the state-dependent retrieval of a passive avoidance task learned under morphine influence have been investigated in mice. Pre-training administration of morphine (0.5, 2.5 and 5 mg/kg) dose dependently suppressed the learning of one-trial passive avoidance task. Pre-test administr...

متن کاملSocial contagion with degree-dependent thresholds
We investigate opinion spreading by a threshold model in a situation in which the influence of people is heterogeneously distributed. We assume that there is a coupling between the influence of an individual (measured by the out-degree) and the threshold for accepting a new opinion or habit. We find that if the coupling is strongly positive, the final state of the system will be a mix of differ...
متن کاملStep - by - Step Evolution with State - Dependent Mutations ∗
This paper considers the application of Ellison’s (2000) “RadiusModified Coradius” Theorem to models of evolution with state-dependent mutations. A reformulated theorem is presented, with a crucial role played by the most probable evolutionary paths between states. The form of such paths is liable to change outside of the uniform mutations case, with concomitant effects on both long-run selecti...
متن کاملContagion and the state in Europe, 1830–1930
"indigenous human capital". Beyond this, Eckart's work brings out a number of overarching themes that deserve special attention. One is the influence of racism and racial hygiene on much of German health care in the colonies. It found its tangible expression in the strict segregation of European and indigenous patients in colonial hospitals, and in the support by doctors for efforts to separate...
