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.
From Wikipedia, the free encyclopedia. The spinoreticular tract is an ascending pathway in the white matter of the spinal cord, positioned closely to the lateral spinothalamic tract.The tract is from spinal cordâto reticular formation â to thalamus.he spinoreticular tract utilizes four levels of neurons, unlike most ascending tracts which have first-through third-order neurons. The tract begins with first-order neurons, which immediately synapse with second-order neurons in the posterior horn of the spinal column.
