The proposed paper will present first results of a research project investigating how nursing homes in Switzerland deal with migrant elders who are in intensive need of care. Focusing on the end-of-life in institutional care settings, the intention is to explore the dimensions of ‘doing death’ in Swiss nursing homes when the elderly involved are of migrant background. The focus is laid on the co-construction of end of life in interactions between residents of migrant background and professional carers involved (often of migrant background themselves), and will thereby focus on processes of ‘doing diversity’ while ‘doing death’. To do so, we chose an ethnographic approach focusing on the participant observation of everyday practices of ‘doing death’ and ‘death work’ and on interviewing staff, residents and their relatives. Caring for ageing migrants at the end of their lives is studied in different types of assisted living at the end of life: The field of research was entered by studying a group specific department for residents of so-called ‘Mediterranean’ background. It was contrasted by a department stressing the individuality of each resident but including a considerable number of residents with migrant background. We are interested in how (and if at all) specific forms of ‘doing community’ within different types of departments may also lead to specific ways of ‘doing death’, which aim at a stronger embeddedness of dying trajectories in social relations of reciprocity and exchange. Furthermore, migrant ‘doing death’ is expected to be particularly negotiable since the potential diversities of symbolic reference systems and daily practices are widened. If the respective resident is limited in his/her capacities to play an active part in negotiating about ‘good care’ and ‘good dying’ – either due to language competences, which would be migrant specific, or due to degenerative diseases, which is not migrant specific – the field of negotiations will be left up to the professionals within the organization (and to the relatives, which are, however, not constantly present). Strategies of stereotyping the ‘other’ as well as driving nurses, caring aides and other professionals of migrant background into roles of ‘cultural experts’ or ‘transcultural translators’ are expected to be common in such situations. However, the task of negotiating what would be a ‘good dying’ and what measures are appropriate is always at stake in contemporary heterogeneous societies. Therefore we would argue that studying dying processes involving migrant residents is looking at paradigmatic manifestations of doing death in recent contexts of reflexive modernity.

This review discusses the neurophysiology and neuroanatomy of the cortical control of reflexive and volitional saccades in humans. The main focus is on classical lesion studies and studies using the interference method of transcranial magnetic stimulation (TMS). To understand the behavioural function of a region, it is essential to assess oculomotor deficits after a focal lesion using a variety of oculomotor paradigms, and to study the oculomotor consequences of the lesion in the chronic phase. Saccades are controlled by different cortical regions, which could be partially specialised in the triggering of a specific type of saccade. The division of saccades into reflexive visually guided saccades and intentional or volitional saccades corresponds to distinct regions of the neuronal network, which are involved in the control of such saccades. TMS allows to specifically interfere with the functioning of a region within an intact oculomotor network. TMS provides advantages in terms of temporal resolution, allowing to interfere with brain functioning in the order of milliseconds, thereby allowing to define the time course of saccade planning and execution. In the first part of the paper, we present an overview of the cortical structures important for saccade control, and discuss the pro's and con's of the different methodological approaches to study the cortical oculomotor network. In the second part, the functional network involved in reflexive and volitional saccades is presented. Finally, studies concerning recovery mechanisms after a lesion of the oculomotor cortex are discussed.
