In behaving cats trained to press a bar for small aliquots of milk reward, single neuronal firing patterns were monitored from the nucleus reticularis (NR) thalami during bar bressing (BP), subsequent quiet wakefulness with EEG spindles (S- QW ), grooming behavior (GR) and slow-wave sleep (SWS). The temporal patterns in the neuronal spike trains were(More)
BACKGROUND Team care can improve management of chronic conditions, but implementing a team approach in an academic primary care clinic presents unique challenges. OBJECTIVES To implement and evaluate the Teamlet Model, which uses health coaches working with primary care physicians to improve care for patients with diabetes and/or hypertension in an(More)
BACKGROUND Many patients with chronic disease do not reach goals for management of their conditions. Self-management support provided by medical assistant health coaches within the clinical setting may help to improve clinical outcomes, but most studies to date lack statistical power or methodological rigor. Barriers to large scale implementation of the(More)
The first phase of this study involves injecting a different fluorescent retrograde axonal tracer into the subthalamic nucleus, the substantia nigra, and the mesopontine tegmentum. Multiple labeled cells are found within the caudal third of the globus pallidus. The entopeduncular nucleus and adjacent basal forebrain structures such as the substantia(More)
Existing skin mechanical testing devices focus on measuring skin elasticity and are not tailored to assess the dynamic behavior of skin. The mathematical techniques used to analyze data collected using these devices are often not optimal. A new dynamic mechanical device that measures the linear dynamics of skin was developed and tested. The mechanical(More)
CONTEXT The 15-minute office visit to primary care clinicians cannot meet the health care needs of patients. Innovation is needed to address this limitation, but practice redesign is challenging in clinical settings. OBJECTIVE Here we describe the implementation of a practice innovation, the teamlet model, in a San Francisco safety-net clinic. The teamlet(More)
BACKGROUND Although self-management support improves diabetes outcomes, it is not consistently provided in health care settings strained for time and resources. One proposed solution to personnel and funding shortages is to utilize peer coaches, patients trained to provide diabetes education and support to other patients. Coaches share similar experiences(More)
In behaving cats, temporal patterns of neuronal firing were studied during slow wave sleep (SWS), motionless quiet wakefulness (QW) coupled with specific direction of the animal's attention, and during bar pressing performance (BP) for milk reward. The analysis was based on relative relations between sequential spike intervals. The strength of the method is(More)
