Rats with neurotoxic lesions of the perirhinal cortex (n = 9) were compared with sham controls (n = 14) on a working memory task in the radial arm maze. Rats were trained under varying levels of proactive interference and with different retention intervals. Finally, performance was assessed when the maze was switched to a novel room. None of these manipulations differentially impaired rats with...

The hippocampal formation is known for its importance in conscious, declarative memory. Here, we report neuroimaging evidence in humans for an additional role of the hippocampal formation in nonconscious memory. We maskedly presented combinations of faces and written professions such that subjects were not aware of them. Nevertheless, the masked presentations activated many of the brain regions...

We investigated how the hippocampus and its adjacent mediotemporal structures contribute to contextual and noncontextual declarative memory retrieval by manipulating the amount of contextual information across two levels of the same contextual dimension in a source memory task. A first analysis identified medial temporal lobe (MTL) substructures mediating either contextual or noncontextual retr...

however, a new restriction, banning a specific late-term abortion procedure, was the focal point in numerous states. And for the first time in seven years, no measures were enacted to safeguard abortion clinics and providers from harassment and acts of violence. The drop in state-level activity in this area is likely attributable to a decease in the number of reported incidents against abortion...

The mechanism for the basal targeting of the Miranda (Mira) complex during the asymmetric division of Drosophila neuroblasts (NBs) is yet to be fully understood. We have identified conserved Phosphotyrosyl phosphatase activator (PTPA) as a novel mediator for the basal localization of the Mira complex in larval brain NBs. In mutant Ptpa NBs, Mira remains cytoplasmic during early mitosis and its ...

Do economic considerations shape attitudes toward immigration? In this article, we consider the relationship between economic interests and immigration preferences by examining how developments in individuals’ sectors of employment affect these views. Using survey data across European countries from 2002 to 2009 and employing new measures of industry-level exposure to immigration, we find that ...

Volume 31, Number 1, January/February 1999 termination using methotrexate started to appear in both the medical and popular literature.3 Interest in this method grew rapidly within the community of abortion providers. In spring 1996, the National Abortion Federation (NAF) devoted its annual postgraduate symposium to medical abortion, including both mifepristone and methotrexate, and the Planned...

35.1 Preliminaries This chapter discusses how linguistic expressions may change their meaning over time. Actually the scope is a bit more limited than that, in the sense that here we will only see examples of how words  e.g. silly, very  change their meaning. The term 'linguistic expressions' includes words, but also larger grammatical constructions. Grammatical constructions  e.g. what in p...
