Test Overview. An electromyogram (EMG) measures the electrical activity of muscles when they're at rest and when they're being used. Nerve conduction studies measure how well and how fast the nerves can send electrical signals. Nerves control the muscles in the body with electrical signals called impulses.
From Wikipedia... <br /><br /> The mycelia of truffles form symbiotic relationships with the roots of several tree species including beech, oak, birch, hornbeam, hazel and pine[5][6].
A truffle is the fruiting body of a subterranean Ascomycete fungus, predominantly one of the many species of the genus Tuber. Truffles are ectomycorrhizal fungi and are therefore usually found in close association with tree roots. Spore dispersal is accomplished through fungivores, animals that eat fungi.
