Kuniomi Ishimori and Henri Piéron were the first researchers to introduce the concept and experimental evidence for a chemical factor that would presumably accumulate in the brain during waking and eventually induce sleep. This substance was named hypnotoxin. Currently, the variety of substances which have been shown to alter sleep includes peptides,(More)
Sleep is a fundamental state necessary for maintenance of physical and neurological homeostasis throughout life. Several studies regarding the functions of sleep have been focused on effects of sleep deprivation on synaptic plasticity at a molecular and electrophysiological level, and only a few studies have studied sleep function from a structural(More)
Neuroglobin (Ngb), a protein located in the mammal's brain, is involved in oxygen transport and free radical scavenging inside the neurons. Ngb colocalizes with choline acetyltransferase in the laterodorsal tegmental nucleus and in the pontine tegmental nucleus, both involved in the sleep-wake cycle regulation. Some studies have shown that free radicals(More)
Growth hormone (GH) plays an important role in cognitive processes such as memory consolidation, and it has been suggested that could be involved in processes of brain plasticity. These changes may occur by promoting gene expression in the brain. In this study we showed that GH administration (5ng/kg) for 7 days improves spatial learning and promotes(More)
