People who have remitted from depression are at increased risk for relapse if they rate their relatives as being critical of them on a simple self-report measure of Perceived Criticism (PC). To explore neural mechanisms associated with this we used functional magnetic resonance imaging (fMRI) to examine how people with different levels of PC responded to(More)
Surveys have revealed that highly mobile people nowadays are most interested in having the services they use at home or at the office available to them while on the road, too. The widespread use of paging and mobile phones proves this-or the well established reception of AM and FM radio broadcasting in motorcars. In towns or hilly areas, the terrestrial(More)
Neuroscientists have become increasingly interested in exploring dynamic relationships among brain regions. Such a relationship, when directed from one region toward another, is denoted by "effective connectivity." An fMRI experimental paradigm which is well-suited for examination of effective connectivity is the slow event-related design. This design(More)
Modern pupillometry has expanded the study and utility of pupil responses in many new domains, including psychiatry, particularly for understanding aspects of cognitive and emotional information processing. Here, we review the applications of pupillometry in psychiatry for understanding patients' information processing styles, predicting treatment, and(More)
There are many planning applications that require an agent to coordinate its activities with processes that change continuously over time. Several proposals have been made for combining a temporal logic of time with the differential and integral calculus to provide a hybrid calculus suitable for planning applications. We take one proposal and explore some(More)
OBJECTIVE In clinically anxious individuals, selective attention to negative cues in the environment may perpetuate a vicious cycle of emotional dysfunction. However, very little is known regarding the role of negative attentional bias in anxious older adults. There is evidence that in older adults without clinical anxiety, the opposite bias (toward(More)
We have experimented with the extent to which we can use a commercial Bluetooth 14 channel EEG system (Emotiv TM) for EEG and ERP analyses. We compared 8 people on an Emotiv and Biosemi Active II system. We have also scanned about 200 other people using the Emotiv and have a corpus of nearly 700 people from around the world which we've been analyzing. Based(More)
