Burning lithium metal produces lithium oxide. Lithium oxide forms along with small amounts of lithium peroxide when lithium metal is burned in the air and combines with oxygen at temperatures above 100 °C: [3] 4Li + O 2 → 2 Li 2 O. Pure Li 2 O can be produced by the thermal decomposition of lithium peroxide, Li 2 O 2, at 450 °C [3] [2] 2 Li ...
Lithium carbonate is an important industrial chemical. Its main use is as a precursor to compounds used in lithium-ion batteries. Glasses derived from lithium carbonate are useful in ovenware. Lithium carbonate is a common ingredient in both low-fire and high-fire ceramic glaze. It forms low-melting fluxes with silica and other materials.
Lithium also stimulates neurogenesis within the hippocampus, making it thicker. [48] Yet another cause of Alzheimer's disease is the dysregulation of calcium ions within the brain. [49] Too much or too little calcium within the brain can lead to cell death. [49]
The soft drink 7Up was originally named "Bib-Label Lithiated Lemon-Lime Soda" when it was formulated in 1929 because it contained lithium citrate. The beverage was a patent medicine marketed as a cure for hangover. Lithium citrate was removed from 7Up in 1948 [5] after the Food and Drug Administration banned its use in soda. [6]
Long-term potentiation (LTP) is a persistent increase in synaptic strength following high-frequency stimulation of a chemical synapse.Studies of LTP are often carried out in slices of the hippocampus, an important organ for learning and memory.
Astrocytes surrounding capillaries in the brain to form the blood brain barrier. This barrier creates a tight hydrophobic layer around the capillaries in the brain, inhibiting the transport of large or hydrophilic compounds. In addition to the BBB, the choroid plexus provides a layer of protection against toxin absorption in the brain.
In Source Code, Gates opens up about “generating so much turmoil” as a boy — a self-described "smart aleck" with a penchant for being "particularly mean.". He recalls one episode that ...
Sleep deprivation and light therapy both target the same brain neurotransmitter system and brain areas as antidepressant drugs, and are now used clinically to treat depression. [28] Light therapy, sleep deprivation and sleep time displacement (sleep phase advance therapy) are being used in combination quickly to interrupt a deep depression in ...
