Activity and plasticity in the CA1, the dentate gyrus, and the amygdala following controllable vs. uncontrollable water stress.

Abstract: The level of controllability has been shown to modulate the effects of stress on physiology and behavior. In the present study, we investigated the effects of controllable vs. uncontrollable stressors on plasticity in hippocampal CA1, the dentate gyrus (DG), and basal amygdala nucleus (B) in the rat, using the electrophysiological procedure of long-term potentiation (LTP). A naive group was left undisturbed until the electrophysiological recording commenced. Rats of the two controllable stress groups were trained in the Morris water maze to locate an invisible underwater platform (the first group), or visible platform (the second group), thus escaping from the water, before the recording. The uncontrollable stress group underwent the same procedure (exposure time to water was adjusted to the averaged exposure time of the first controllable group) without the escape platform. We first assessed the effects of stress and controllability on LTP in CA1. Both controllable stressors and the uncontrollable stress impaired CA1 LTP, with a more robust effect induced by the uncontrollable stress. We further assessed the effects of the same procedures on LTP in DG and B. The uncontrollable stress enhanced LTP in DG and increased baseline responses (suggesting uncontrollable stress-induced plasticity) in the amygdala. All the stressors decreased amygdalar LTP. An assessment of plasma levels of corticosterone (CORT), following the behavioral procedures, revealed an enhancement in CORT release following the uncontrollable, but not controllable stress, indicating the uncontrollable condition as the most stressful. These findings provide insight into the differential effects of stress and stress controllability on different hippocampal subregions and the amygdala.

International Migration, Domestic Work, and Care Work Undocumented Latina Migrants in Israel

Abstract: This article discusses three major dilemmas embedded in women's labor migration by focusing on undocumented Latina migrants in Israel. The first is that to break the cycle of blocked mobility in their homelands, migrant women must take jobs that they would have never taken in their countries of origin, despite uncertainty about possible economic outcomes. The second dilemma is that the search for economic betterment leads Latina migrants to risk living and working illegally in the host country, forcing them to remain on the margins of society. The third dilemma relates to the role of mothers who, to secure a better future for their children, are forced to leave them behind, thus subverting the traditional definition of motherhood. The absence of an egalitarian notion and the practice of citizenship for non-Jews leave undocumented labor migrants in Israel without prospects for incorporation into the society.
