The medial subdivision of the monkey nucleus accumbens (NAC) is rich in dopamine (DA) and peptides. In the present investigation the mode of DA transmission in the medial subdivision was studied morphologically by light- and electron-microscopic immunocytochemistry using a monoclonal antibody raised against dopamine. The medial subdivision showed extremely(More)
In order to further investigate the neurochemical anatomy of the primate nucleus accumbens (NAC), the distributions of the neuropeptides leucine-enkephalin (Leu-ENK), neurotensin (NT), and substance P (SP) and of haloperidol-induced c-fos expression were investigated in the macaque monkey using immunohistochemical methods. To define the boundaries of the(More)
Purpose. We investigated the effect of nitroglycerin(NTG) on fractal features of short-term heart rate variability (HRV) and blood pressure variability (BPV) using coarse-graining spectral analysis (CGSA). Method. Nine healthy young volunteers participated in this study. Five-minute recordings of electrocardiogram and blood pressure estimated by(More)
In this paper, we examine the parametrization of all proper stabilizing controllers for multiple-input/multiple-output minimum phase systems. Glaria and Goodwin first gave the parametrization of all stabilizing controllers for the single-input/single-output minimum phase systems. Their parametrization has practical difficulties. One is the free parameter of(More)
We give an explicit parameterization of all causal stabilizing repetitive controllers for single-input/single-output continuous time non-minimum phase systems of a certain class. When the plant meets certain conditions, using the parallel compensation technique, we obtain the parameterization of all repetitive controllers. Finally, a numerical example shows(More)
In this paper, we examine the parametrization of all stabilizing multiperiod repetitive controllers with the specified frequency characteristics. The parametrization of all stabilizing multi-period repetitive controllers, those are used to improve the disturbance attenuation characteristics of the repetitive controller, for non-minimum phase systems was(More)
The pharmacological characteristics of two benzamides, YM-43611, a potent and selective dopamine D3 and D4 antagonist, and YM-09151-2 (nemonapride), were compared with two reference antipsychotic agents, haloperidol and clozapine, in terms of modification of c-fos and related gene expression in the rat forebrain. After subcutaneous injection of YM-43611 (1(More)
Post-mortem brain tissue was obtained from 28 patients with brain disorders, of which 15 had clinically diagnosed schizophrenia, 6 Alzheimer type dementia, 5 dementia with tangles and 2 cases of Down's syndrome. The controls were 22 cases from autopsies without brain disorders or with no known episodes of brain disorder. The tissues were stained for the(More)
In this paper, we examine the parametrization of all stabilizing repetitive controllers for multiple-input/multiple-output continuous time time-delay systems. Yamada, Satoh and Arakawa considered the parametrization of all stabilizing repetitive controllers for single-input/single-output time-delay systems. However, the parametrization by Yamada, Satoh and(More)
