This paper describes the outline of an object-oriented design technique denoted role modeling, emphasizing the ability to compose parts of a design. The purpose of role model-ing is to achieve separation of concerns, allowing the designer to consider different aspects, or the same aspect at different levels of detail, more or less independent of other(More)
The response of medial thalamic neurons to noxious peripheral stimulation were studied with intracellular recording methods in the cat. Electrical stimulation of the contralateral forepaw produced an EPSP-IPSP sequence followed by rebound excitation in these medial thalamic neurons. Action potentials appeared with the initial EPSP or with the rebound(More)
We have recently reported that luteinizing hormone (LH) is present in the hypothalamus of rats. It has chromatographic and biologic characteristics similar to pituitary LH. In this report we focus on extrahypothalamic LH that is widely distributed in the rodent central nervous system. This material has a chromatographic profile similar to that of pituitary(More)
Ultracentrifugation and sucrose gradient separation techniques have been applied to study of the subcellular distribution of hypothalamic luteinizing hormone (LH). Subcellular particle-bound LH accounted for 42% of the total LH while cytoplasm contained 58% of the total immunoassayable LH in these extracts. 70% of particle-bound LH was present in the P2(More)
The advent of shared care coupled with the proliferation of heterogeneous distributed systems containing patient data have resulted in an urgent need to provide seamless integration of distributed electronic patient records. This paper presents the approach to this problem, which is being developed as part of a major EU (European Union) Health Telematics(More)
Spontaneous activity, responses to noxious stimulation and response to electrical stimulation of the dorsal raphe were recorded extracellularly from single units in the parafascicularis (PF) nucleus in the rat. Three types of spontaneous activity were found: 'slow' firing units (1-10 spikes/sec), 'bursting' units (bursts of 2-5 spikes/10-20 msec, bursts(More)
The dorsal raphe nucleus (DR) was examined for its possible modulatory effects on sensory input to the caudate nucleus (CN) and lateral septum (Spt) in freely behaving rats. Three types of DR stimulation were tested for their effects on sensory evoked responses: (1) a single pulse of electrical stimulation of the DR prior to each sensory stimulus, (2) a(More)
The decisions made in a ~stem 's so~'are architecture have a major impact on the qua/ity of the resu/ting ~stem. The goa/ of softwore architecture ana/ysis is to assess whether these decisions /ead to the required qua/ity. Dur research concentrates on sofiware architecture ana/ysis of administrative ~stems. In this paper, we focus on the qua/ity attribute(More)
Three types of spontaneously active neurons were found in the parafascicularis (PF) nucleus of the thalamus of the rat: slow firing units (0.5-10 spikes/s), bursting units (2-5 spikes/burst in 10-20 ms, one burst every 1-2 s) and fast firing units (15-40 spikes/s). A similar population of neurons was found in the PF of rats treated with(More)
