Recent epidemiological studies indicate that obesity increases the incidence of depression. We examined the implication of leptin for obesity-associated depression. Leptin induced antidepressive behavior in normal mice in a forced swimming test (FST), and leptin-overexpressing transgenic mice with hyperleptinemia exhibited more antidepressive behavior in(More)
Orexins and melanin-concentrating hormone (MCH) as orexigenic neuropeptides are present in the lateral hypothalamus, and their receptors are distributed in the cerebral cortex and hippocampus. In the present study, the regulatory effects of orexin-A, orexin-B and MCH on neurotrophin-3 (NT-3) and brain-derived neurotrophic factor (BDNF) expressions were(More)
Orexin is one of the orexigenic neuropeptides in the hypothalamus. Orexin neurons in the lateral hypothalamus (LH) project into the cerebral cortex and hippocampus in which the receptors are distributed in high concentrations. Therefore, to elucidate the actions of orexin in the cerebral cortex, we examined its effects on the mRNA expressions of(More)
This study will investigate how non-native speakers of Japanese acquire Japanese accentuation from the viewpoint of the location of the accent nucleus. Hypothetical models for the process of generation and for developmental sequence of interlanguage Japanese accentuation, which is interim accentual system created by learners, will be proposed. The subjects(More)
