The assessment of causal relationships between exposure and disease usually requires epidemiological studies. Randomized trials on humans are rarely achievable but can sometimes be accomplished in a secondary follow-up of the long-term side effects, e. g., of drugs. The association between smoking and lung cancer is a classical example of important information discovered by epidemiological studies

Over the past few decades, there has been an increase in the number of children receiving home mechanical ventilation (HMV), and in many ways, families have taken responsibility for the required advanced homecare, which has placed considerable time demands on the family unit. Little is known about the life situation of the siblings of HMV-assisted children; their own voices and an insider perspect

Aim: To analyse and synthesise the research that has investigated the experience of home in relation to home mechanical ventilation (HMV). Method: Systematic integrative review. Four electronic databases (CINAHL, PubMed, Scopus and ISI Web of Knowledge) were searched between January 2010 and April 2017 as well as reference lists of included studies. Quantitative and qualitative studies meeting the

By giving a brief overview of the metaconcepts in nursing, with a focus on environment, we sketch a theoretical framework for an emancipatory perspective in nursing care practice. To meet the requirements of equality in care and treatment, we have in our theoretical framework added a critical lifeworld perspective to the antioppressive practice, to meet requirements of equity in health care encoun

Parkinsons sjukdom är den näst vanligaste neurodegenerativa sjukdomen. Lewykroppar med alfa-synuklein som huvudbeståndsdel och förlust av dopaminerga nervceller i substantia nigra är neuropatologiska kännetecken. Diagnosen baseras på förekomst av bradykinesi och rigiditet eller vilotremor. Sjukdomen är också förknippadmed många icke-motoriska symtom. Behandlingen baserar sig främst på farmakologisParkinson's disease is the second most common neurodegenerative disease. Lewy bodies with alpha-synuclein as the major component and loss of dopaminergic nerve cells in substantia nigra are neuropathological features. The diagnosis of Parkinson's disease is based on the occurrence of bradykinesia, rigidity and resting tremor. The disease is also associated with several non-motor symptoms. The ther

To what extent does the visual system process color and form separately? Proponents of the segregation view claim that distinct regions of the cortex are dedicated to each of these two dimensions separately. However, evidence is accumulating that color and form processing may, at least to some extent, be intertwined in the brain. In this perspective, we review psychophysical and neurophysiological

The impairment of multisensory integration in schizophrenia is often explained by deficits of attentional selection. Emotion perception, however, does not always depend on attention because affective stimuli can capture attention automatically. In our study, we specify the role of attention in the multisensory perception of emotional stimuli in schizophrenia. We evaluated attention by interference

In scrutinizing a scene, the eyes alternate between fixations and saccades. During a fixation, two component processes can be distinguished: visual encoding and selection of the next fixation target. We aimed to distinguish the neural correlates of these processes in the electrical brain activity prior to a saccade onset. Participants viewed color photographs of natural scenes, in preparation for

Analyzing single trial brain activity remains a challenging problem in the neurosciences. We gain purchase on this problem by focusing on globally synchronous fields in within-trial evoked brain activity, rather than on localized peaks in the trial-averaged evoked response (ER). We analyzed data from three measurement modalities, each with different spatial resolutions: magnetoencephalogram (MEG),

Adaptation is widely used as a tool for studying selectivity to visual features. In these studies it is usually assumed that the loci of feature selective neural responses and adaptation coincide. We used an adaptation paradigm to investigate the relationship between response and adaptation selectivity in event-related potentials (ERPs). ERPs were evoked by the presentation of colored Glass patter

Perceptual interpretation of the same multisensory stimuli may rely upon influence of attention on multisensory integration. We tested this hypothesis by recording the brain activity using magnetoencephalography in a passing-bouncing illusion with sound. Early activation of the attention-related brain areas and subsequent involvement of the multisensory areas were associated with the bouncing perc

We considered the hypothesis that spontaneous dissociation between the direction of attention and eye movement causes encoding failure in change detection. We tested this hypothesis by analyzing eye fixation-related potentials (EFRP) at the encoding stage of a change blindness task; when participants freely inspect a scene containing an unmarked target region, in which a change will occur in a sub

We investigated the relationship between visual experience and temporal intervals of synchronized brain activity. Using high-density scalp electroencephalography, we examined how synchronized activity depends on visual stimulus information and on individual observer sensitivity. In a perceptual grouping task, we varied the ambiguity of visual stimuli and estimated observer sensitivity to this vari

We investigated the brain responses to the transitions from the static to moving audiovisual stimuli using magnetoencephalography. The spatially congruent auditory and visual stimuli moved in the same direction whereas the incongruent stimuli moved in the opposite directions. Using dipole modeling we found that the static-to-moving transitions evoked a neural response in the primary auditory corte

Selection of visual short-term memory content takes place during perceptual and postperceptual processing. We studied postperceptual selection in a change detection task, in which spatially distributed cues preceding the memory array marked potential change targets. In the 550-730ms interval after the memory array onset but not in the following retention interval, event-related potentials showed l

Visual integration between target and irrelevant features leads to effects of irrelevant feature congruency (Stroop) or variation (Garner) on target classification performance. Presenting closed geometrical shapes as stimuli, we obtained Stroop and Garner effects of one part of their contour on another, in response times and error rates. The correlates of these effects in brain activity were obser
