During the prenatal period, the development of individual is influenced by the environmental factors. In the present study, the influence of prenatal noise and music on the spatial memory and neurogenesis in the hippocampus of developing rats was investigated. The exposure to the noise during pregnancy caused growth retardation, decreased neurogenesis in(More)
It has been suggested that exercise may ameliorate neurologic impairment by impeding neuronal loss following various brain insults. In the present study, the effect of long-term treadmill exercise on short-term memory and apoptotic neuronal cell death in the hippocampus following transient global ischemia in gerbils was investigated. A step-down inhibitory(More)
The impact of age on the effect of treadmill exercise on cell proliferation in the dentate gyrus of rats was investigated via 5-bromo-2'-deoxyuridine immunohistochemistry. Animals of different ages were used: 4-week-old, 8-week-old, and 62-week-old. Based upon the present study, the most prominent cell proliferation in the dentate gyrus was observed in the(More)
In the present study, the effects of maternal swimming during pregnancy on the short-term memory ability, hippocampal neurogenesis, and brain-derived neurotrophic factor (BDNF) mRNA expression of rat pups were investigated. After confirming their pregnancy, the pregnant rats were divided into two groups: the control group and the swimming group. From the(More)
Maternal ethanol consumption during pregnancy has a detrimental effect on the central nervous system (CNS) development of fetus. 5-Hydroxytryptamine (5-HT) is an important neurotransmitter and/or neuromodulator in the mammalian CNS. Tryptophan hydroxylase (TPH) is the rate limiting enzyme of 5-HT synthesis. Ethanol is known to induce neuropsychiatric(More)
The amounts of puffer toxin (tetrodotoxin, TTX) extracted from the fresh and the traditional Japanese salted and fermented "Nukazuke" and "Kasuzuke" ovaries of Takifugu stictonotus (T. stictonotus) were quantitatively analyzed in the voltage-dependent sodium current (I(Na)) recorded from mechanically dissociated single rat hippocampal CA1 neurons. The(More)
Acupuncture has been used for the enhancement of functional recovery from various disorders including stroke. In the present study, the effects of acupuncture on the c-Fos expression and apoptosis in the hippocampal CA1 region of gerbils following transient global ischemia were investigated via immunohistochemistry for c-Fos and caspase-3 and terminal(More)
We evaluated the effects of propofol on synaptic transmission using a mechanically dissociated preparation of rat hippocampal CA3 neurons to allow assays of single bouton responses evoked from retained functional native nerve endings. We studied synaptic and extrasynaptic GABAA and glutamate receptor responses in a preparation in which experimental(More)
Cerebral ischemia resulting from transient or permanent occlusion of cerebral arteries leads to neuronal cell death and eventually causes neurological impairments. In the present study, the effects of treadmill exercise on apoptosis and cell proliferation in the hippocampal dentate gyrus following transient global ischemia in gerbils were investigated using(More)
Intracerebral hemorrhage is one of the most devastating types of stroke. This disease is known to cause severe neurological damage and also has a very high mortality rate. In this study, the effect of treadmill exercise on intrastriatal hemorrhage-induced neuronal cell death was investigated. Intrastriatal hemorrhage was caused by injection of collagenase(More)
