1 Future-Spot spread model assumes that future oil spot price is determined by a combination of current spot price and current futures price, and a properly constructed spread between these two current prices can predict the future oil spot price. 2  Mathematically, the model could be presented as:
corticospinal tract The nervous system tract that conducts impulses from the brain to the spinal cord. It contains mostly motor axons and is made up of two separate tracts in the spinal cord: the lateral corticospinal tract and the anterior corticospinal tract.
