Neurogenesis in the dentate gyrus of the rat hippocampus enhanced by tickling stimulation with positive emotion.
Hippocampal neurogenesis is influenced by many factors. In this study, we examined the effect of tactile stimulation (tickling), which induced positive emotion, on neurogenesis in the dentate gyrus (DG) of the hippocampus. Four week-old rats were tickled for 5 min/day on 5 consecutive days and received 5-bromo-2'-deoxyuridine (BrdU) administration for 4 days from the second tickling day. Then t...
متن کاملAdult neurogenesis in the mammalian hippocampus: why the dentate gyrus?
In the adult mammalian brain, newly generated neurons are continuously incorporated into two networks: interneurons born in the subventricular zone migrate to the olfactory bulb, whereas the dentate gyrus (DG) of the hippocampus integrates locally born principal neurons. That the rest of the mammalian brain loses significant neurogenic capacity after the perinatal period suggests that unique as...
متن کامل[Neurogenesis in the dentate gyrus of the hippocampus in a rat model of intracerebral hemorrhage].
OBJECTIVE To investigate whether intracerebral hemorrhage (ICH) can promote neurogenesis in the dentate gyrus (DG) of rat hippocampus. METHODS Western blot analysis, immunohistochemical staining, and immunofluorescent double labeling combined with confocal microscope were used to detect neurogenesis in the DG of the hippocampus in rats after ICH. RESULTS The expression of DCX protein in the...
متن کاملNeurogenesis in the adult rat dentate gyrus is enhanced by vitamin E deficiency.
Neurogenesis occurs throughout adult life in rat dentate gyrus. Factors and mechanisms of adult neurogenesis regulation are not well known. Vitamin E deficiency has been found to deliver a neurogenetic potential in rat dorsal root ganglia. To determine whether the role of tocopherols in adult neurogenesis may be generalized to the central nervous system, changes in adult rat dentate gyrus neuro...
متن کاملNovel Control by the CA3 Region of the Hippocampus on Neurogenesis in the Dentate Gyrus of the Adult Rat
The dentate gyrus is a site of continued neurogenesis in the adult brain. The CA3 region of the hippocampus is the major projection area from the dentate gyrus. CA3 sends reciprocal projections back to the dentate gyrus. Does this imply that CA3 exerts some control over neurogenesis? We studied the effects of lesions of CA3 on neurogenesis in the dentate gyrus, and on the ability of fluoxetine ...
