Despite recent advances, psychogenic movement disorder (PMD) remains a poorly understood phenomenon. Emotional functioning and responsiveness to stress are believed to play a role in the development of psychogenic symptoms, but empirical studies examining emotional responsiveness in PMD and other conversion disorders are lacking. We investigated modulation(More)
The amygdala is closely linked to basal ganglia circuitry and plays a key role in danger detection and fear-potentiated startle. Based on recent findings of amygdalar abnormalities in Parkinson's disease, we hypothesized that non-demented patients with this illness would show blunted reactivity during aversive/unpleasant events, as indexed by diminished(More)
In humans, the neural circuitry underlying facial expressions differs, depending on whether facial expressions are spontaneously (i.e., limbic, subcortical) or voluntarily initiated (i.e., frontal cortex). Previous investigators have suggested that the "masked face" of Parkinson's disease involves spontaneous, but not intentional, facial expressions. In(More)
Background. The Microsoft Kinect presents a simple, inexpensive, and portable method of examining the independent components of the Timed Up and Go (TUG) without any intrusion on the patient. Objective. This study examined the reliability of these measures, and whether they improved prediction of performance on common clinical tests. Methods. Thirty(More)
Given the rapidly ageing population, interest is growing in robots to enable older people to remain living at home. We conducted a systematic review and critical evaluation of the scientific literature, from 1990 to the present, on the use of robots in aged care. The key research questions were as follows: (1) what is the range of robotic devices available(More)
Living Profiles is a health media platform in development that aggregates multiple data flows to help teens with special healthcare needs (SHCN), particularly with regard to self-management and independence. A teen-oriented personal health record (PHR) incorporates typical teen behaviors and attitudes about health and wellness, encompasses how teens(More)
Living Profiles is a personal health record (PHR) designed for and by teens with chronic diseases transitioning from the world of pediatric care to the adult system of medical care. It incorporates typical teen behaviors and attitudes about health and wellness while promoting independence, empowerment, and self-care. Our multi-disciplinary team of(More)
The key to improved prognosis for melanoma is early detection and diagnosis, achieved by skin surveillance and secondary prevention (screening). However, adherence to screening guidelines is low, with population-based estimates of approximately 26% for physician-based skin cancer screening and 20-25% for skin self-examination. The recent proliferation of(More)
Deep brain stimulation (DBS) now plays an important role in the treatment of Parkinson's disease, tremor, and dystonia. DBS may also have a role in the treatment of other disorders such as obsessive-compulsive disorder, Tourette's syndrome, and depression. The neuropsychologist plays a crucial role in patient selection, follow-up, and management of(More)
The inferior colliculus has been well studied for its role of transmitting information from the brainstem to the thalamocortical system. However, it is also the source of a major pathway to the cerebellum, via the pontine gray (PG). We compared auditory responses from single neurons in the medial geniculate body (MGB) and PG of the awake big brown bat. MGB(More)
