The aim of the present study was to investigate the role of dopamine D(3) receptors in the rewarding effect and hyperlocomotion induced by a prototypical mu-opioid receptor agonist morphine using dopamine D(3) receptor knock-out mice. The mu-opioid receptor in the brain determined by the [tylosil-3,5-(3)H(N)]-[D-Ala(2),N-MePhe(4),Gly-ol(5)]enkephalin(More)
In this paper, we present out-of-plane micro-scale diameter light guiding silicon dioxide tube arrays for use in optical stimulation of neurons. An optical propagation through the dioxide tube was calculated by using finite-difference time-domain (FDTD) simulation. Based on the calculated result, we designed and fabricated 3-µm-inner diameter(More)
Here we report vertical metal/silicon dioxide (SiO<sub>2</sub>) multiwalled microtube arrays as electrical and optical neuroprobes for &#x201C;optogenetic&#x201D;. Three-dimensional metal/SiO<sub>2</sub>-microtube arrays can be fabricated by vapor-liquid-solid (VLS) growth of silicon-wire, followed by the SiO<sub>2</sub>/metal depositions and the(More)
The Japan Society for Analytical Chemistry has developed some new plastic certified reference materials (CRMs) for the analysis of mercury in polyester disks using XRF analysis. These CRMs (named as JSAC 0621-0625) were prepared by casting polyesters including a toluene solution of organometallic compounds as a standard. Concentrations of the five levels of(More)
