Brain activity during observation and imagery of gait was investigated. Sixteen subjects were scanned with a 3-Tesla MRI scanner while viewing six types of video clips: observation of gait movement (GO) from the third-person perspective, observation of stepping movement, observation of standing posture, "virtual walking" (VW) that was observation of visual(More)
One of the most powerful ways of succeeding in complex social interactions is to read the minds of companions and stay a step ahead of them. In order to assess neural responses to reciprocal mind reading in socially strained human relationships, we used a 3-T scanner to perform an event-related functional magnetic resonance imaging study in 16 healthy(More)
The development of human social cognition has allowed interactions with other species and the formation of a cooperative multi-species society. This feature posited keen attention on the following question: is heterospecific social cognition represented in the same brain areas as conspecific social cognition? Here we investigated brain activity accompanying(More)
Psychological factors are known to play an extremely important role in the maintenance and development of chronic pain conditions. However, it is unclear how such factors relate to the central neural processing of nociceptive transmission in healthy individuals. To investigate this issue, the activation of the brain was studied in 30 healthy volunteers(More)
People always concern about what they have and what they might lose even it is just imaginary property. According to Prospect Theory, the losses might be weighted by subjects higher than gain, which would cause the disparity between the willingness to accept (WTA) and willingness to pay (WTP) compensation in economic valuation. Using functional MRI, we(More)
Oscillatory brain activity is known to play an essential role in information processing in working memory. Recent studies have indicated that alpha activity (8-13 Hz) in the parieto-occipital area is strongly modulated in working memory tasks. However, the function of alpha activity in working memory is open to several interpretations, such that alpha(More)
A retrospective study was performed on 30 cases with choroidal metastases referred to the Cancer Institute Hospital between July 1975 and June 1986. Of these 30 cases, 32 eyes of 26 patients were treated with irradiation of 4.3 MV X-rays or 12 MeV electron beam therapy in the range of 20-60 Gy to restore vision and prevent blindness. The tumor response to(More)
From 1980 to 1985, 126 patients with a brain metastases from various malignant tumors were treated by hypervoltage irradiation with conventional fractionation at the Department of Radiotherapy at the Cancer Institute Hospital. The patients without an extracranial metastases or without neurological symptoms had a longer survival than did the other patients.(More)
