Any sensory stimuli below an individual's threshold for conscious perception, in contrast to subliminal stimuli.
<h3>
What is subliminal stimulation?</h3>
- An action potential can be produced by a stimulus of sufficient intensity. However, a stimulus whose strength is less than the threshold won't be able to.
- Subliminal refers to the stimulus that is received below threshold.
- To elicit a reaction, there must be a change in the action potential. For example, to trigger a skeletal muscle to contract, the stimulus must be liminal—that is, strong and long enough to result in depolarization and an action potential.
- Skeletal muscle fibres in a motor unit will contract when an action potential is obtained as a result of a series of cascading events.

Let's have in mind that US President Thomas Jefferson had ordered the purchase of the Louisiana Territory owned by the French. So in 1803, after the purchase, Thomas Jefferson ordered the Lewis & Clark expedition to explore the western territories. The Expedition lasted 3 years. After that time President Jefferson was briefed about the findings and that is when he authorized the westward expansion.
