One of the most fundamental and universal properties of human language is a phenomenon called displacement. In the present study, we used multichannel event-related potentials (ERPs) to identify the nature of this phenomenon with Japanese, a subject-object-verb (SOV) language of relatively free word order. The ERPs of sentences of canonical word order (CC)(More)
Accumulating evidence suggests that the serotonin 5-HT(1A) receptor may play a role in the pathophysiology of schizophrenia. The present study was undertaken to examine the effects of perospirone, an atypical antipsychotic drug with 5-HT(1A) receptor agonism, on cognitive deficits in mice after repeated administration of the NMDA receptor antagonist(More)
Because there are sex differences in feeding-related behavior and orexin neurons are involved in feeding, we looked for a possible sex difference in the response of orexin neurons in the lateral hypothalamic area to fasting, using the phosphorylated cyclic AMP response element-binding protein (pCREB) as a marker of neural activity. Intact male and female(More)
BACKGROUND The N-methyl-d-aspartate (NMDA) receptor antagonist phencyclidine (PCP)-induced cognitive deficits have been used as an animal model for schizophrenia. This study was undertaken to determine whether the antibiotic drug minocycline could improve PCP-induced cognitive deficits in mice. METHODS Saline (10 ml/kg/day, s.c., once daily on day 1-5,(More)
The basidiomycetous yeast Pseudozyma antarctica T-34 is an excellent producer of mannosylerythritol lipids (MELs), members of the multifunctional extracellular glycolipids, from various feedstocks. Here, the genome sequence of P. antarctica T-34 was determined and annotated. Analysis of the sequence might provide insights into the properties of this yeast(More)
Pseudozyma antarctica is a non-pathogenic phyllosphere yeast known as an excellent producer of mannosylerythritol lipids (MELs), multi-functional extracellular glycolipids, from vegetable oils. To clarify the genetic characteristics of P. antarctica, we analyzed the 18 Mb genome of P. antarctica T-34. On the basis of KOG analysis, the number of genes (219(More)
The present study was undertaken to examine the effects of mithramycin, an inhibitor of transcription factor Specificity protein (Sp)-1, on the behavioral changes and dopaminergic neurotoxicity in the mouse striatum after administration of methamphetamine (METH). Pretreatment with mithramycin (75, 150 or 300 microg/kg) did not alter acute hyperlocomotion in(More)
Although preclinical studies suggest that methylone (2-methylamino-1-[3,4-methylenedioxyphenyl]propan-1-one) and 5-MeO-MIPT (5-methoxy-N-methyl,N-isopropyl tryptamine) may have psychostimulant properties, the scientific reports about the clinical effects of these agents are scant. We describe a 27-year-old male patient with substance intoxication after a(More)
We examined the effects of tropisetron, a 5-hydroxytryptamine (5-HT(3)) receptor antagonist and alpha7 nicotinic receptor agonist, on cognitive deficits in mice after repeated administration of the NMDA receptor antagonist phencyclidine (PCP). PCP (10 mg/kg/day for 10 days)-induced cognitive deficits were significantly improved by subsequent subchronic (2(More)
The relationship between 2 words is judged by the meanings of words. Here, we examined how the semantic relatedness of words is structured in each individual brain. During measurements of event-related potentials (ERPs), participants performed semantic-relatedness judgments of word pairs. For each participant, we divided word pairs into 2 groups--related(More)
