Optic nerve axons do not regenerate after lesions in postnatal mammals, except if peripheral nerve transplants are offered as a substrate. In the present study, regeneration was assessed after intracranial freeze-crush lesions of the optic nerve, which completely interrupted all axons. In rats lesioned at the age of 8-9 days and surviving for additional 5-6(More)
Lesions of the optic nerve in young animals lead to rapid retrograde degeneration of the axon stumps and to death of retinal ganglion cells. We injected different neurotrophic factors into the eye at the time of an intracranial freeze-crush lesion of the optic nerve in 8 day old rats. Optic nerve axons were visualized by anterograde tracing with wheat germ(More)
This study examined mood disturbance among women with metastatic breast cancer in relationship to partnership status, relationship quality, and partner's coping and mood disturbance. These associations were examined within a total sample of 125 metastatic breast cancer patients and a subsample of 48 of these patients and their partners. Partnered and single(More)
Previous research studies in the context of presence point out the importance of personality factors. Surprisingly, the relation between immersion and the Big Five personality factors has not yet been examined. Hence, we assessed these traits in an online survey (N = 220) and relate them to immersive tendency, a disposition that determines whether someone(More)
Like in the real world, the first impression a person leaves in a computer-mediated environment depends on his or her online appearance. The present study manipulates an avatar's pupil size, eyeblink frequency, and the viewing angle to investigate whether nonverbal visual characteristics are responsible for the impression made. We assessed how participants(More)
Research in cognitive neuroscience and spatial presence suggests that human mental self-localization is tied to one place at a given point in time. In this study, we examined whether it is possible to feel localized at two distinct places at the same time. Participants (N=30) were exposed to a virtual rollercoaster and they continuously judged to what(More)
