In pigmented rabbits anesthetized with N2O (70%) and halothane (2-4%), Purkinje cells were extracellularly recorded in the flocculus. A large central visual field (60 degrees x 60 degrees) was used to optokinetically stimulate either the ipsi- or contralateral eye, and the direction and velocity selectivities of complex spike responses were examined. For(More)
In pigmented rabbits anesthetized with N2O (70%) and halothane (2-4%), Purkinje cells were extracellularly recorded in the nodulus. Large field (60 degrees x 60 degrees) optokinetic stimulation (OKS) with constant velocity was delivered to either the ipsi- or contralateral eye, and the direction and velocity selectivities of complex spike responses were(More)
The previous electrophysiological study reported that some of the Purkinje cells in the vestibulocerebellum were innervated by branching climbing fibers. To identify the cells of origin of these branching climbing fibers, a pair of retrograde fluorescent tracers, propidium iodide in combination with 4', 6-diamidino-2-phenylindole or diamidino yellow, were(More)
Olivocerebellar branching projections to the flocculus, nodulus and uvula were studied electrophysiologically in pigmented rabbits anesthetized with pentobarbital and halothane. Neurons in the dorsal cap of the inferior olive were antidromically activated by stimulation of the contralateral flocculus, nodulus and uvula. The antidromic responses in the(More)
From 1988 to 1992, 1188 children (576 boys and 612 girls) three to 11 years old were studied using the Stasio-analyzer to clarify developmental change of upright postural sway. Developmental change in the contact surface area of the sole, the coefficient of variation for the contact surface area, total sway area, total sway path and position of the centre(More)
We cloned a cDNA for the rat mu-opioid receptor from a rat thalamus cDNA library. The deduced amino-acid sequence of rat mu-opioid receptor consists of 398 residues with the features shared by the members of the G-protein coupled receptor family, and is 59% and 60% identical with those of rat kappa-opioid and mouse delta-opioid receptors, respectively.(More)
Under anesthesia with N2O (70%) and halothane (2-4%), Purkinje cell activities were extracellularly recorded in the flocculus and nodulus of immobilized pigmented rabbits. Large field (60 degrees x 60 degrees) optokinetic stimulation (OKS) was delivered to the central visual field of one eye with a constant velocity (0.1-4.0 degrees/s) at 0 degrees, 45(More)
Coexistence of the mRNA for each subtype of opioid receptor (OPR) with the mRNA for preprotachykinin A (PPTA), a precursor protein of substance P (SP), in the rat dorsal root ganglia was examined by double in situ hybridization technique. About 90% and 30% of PPTA mRNA-positive neurons expressed mu- and kappa-OPR mRNAs at high level, respectively. However,(More)
Neurons in the ventromedial tegmental area that project to the rostral part of the dorsal cap of the ipsilateral inferior olive were labeled by the technique of retrograde transport of horseradish peroxidase (HRP). Following iontophoresis of HRP into the rostral part of the dorsal cap a cluster of labeled cells are found ipsilaterally in the area(More)
