The organization of divergent axonal projections from the midbrain raphe nuclei in the rat
The intranuclear organization of divergently projecting neurons of the midbrain raphe in the rat was studied by using double retrograde axonal tracing. Paired injections of the tracers N‐[acetyl‐3H]… Expand
Clinical heterogeneity of alpha-synuclein gene duplication in Parkinson's disease.
OBJECTIVE Recently, genomic multiplications of alpha-synuclein gene (SNCA) have been reported to cause hereditary early-onset parkinsonism. The objective of this study was to assess the frequency of… Expand

SNCA duplication is a recognized cause of familial Parkinson's disease (PD). We aimed to explore the genetic and clinical variability in the disease manifestation. Molecular characterization was… Expand

Analyses of the MAPT, PGRN, and C9orf72 mutations in Japanese patients with FTLD, PSP, and CBS.
BACKGROUND Mutations in the microtubule associated protein tau (MAPT) and progranulin (PGRN) have been identified in several neurodegenerative disorders, such as frontotemporal lobar degeneration… Expand
Excitotoxic lesions of the pedunculopontine tegmental nucleus produce contralateral hemiparkinsonism in the monkey
Dopaminergic nigrostriatal neurons, degeneration of which causes Parkinson's disease, are known to receive excitatory input almost exclusively from the pedunculopontine tegmental nucleus (PPN). We… Expand

The mechanism of abnormal iron accumulation in the substantia nigra (SN) pars compacta of patients with Parkinson's disease (PD) is unknown. To explore this question, we made a hemiparkinsonism model… Expand
Dopa-unresponsive pure akinesia or freezing. A condition within a wide spectrum of PSP?
Hemiparkinsonism in monkeys after unilateral caudate nucleus infusion of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP): behavior and histology
Systematically administered 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) is biotransformed into 1-methyl-4-phenylpyridinium ion (MPP+), which enters dopaminergic neurons via the dopamine… Expand
Morphology and intracellular responses of an identified dorsal raphe projection neuron
Stimulation of ventral medial tegmentum elicits an antidromic action potential and an inhibitory postsynaptic potential in dorsal raphe projection neurons. The inhibitory postsynaptic potential is… Expand
