In this example we'll use a bell. 1  The Conditioned Stimulus (CS) -- This is the neutral stimulus after it has acquired the ability, through conditioning, to elicit a response. 2  The Conditioned Response (CR) -- This is the response conditioned to the CS. The interval between the start of the CS and the start of the US called the CS-US interval, or alternatively, the interstimulus interval or ISI. 2  In salivary conditioning, the CS-US interval the works best is on the order of 5 to 10 seconds. 3  Repeat this pairing across a number of trials.
Nitrogen is a chemical element with symbol N and atomic number 7. It is the lightest pnictogen and at room temperature, it is a transparent, odorless diatomic gas. Nitrogen is a common element in the universe, estimated at about seventh in total abundance in the Milky Way and the Solar System.On Earth, the element forms about 78% of Earth's atmosphere and as such is the most abundant uncombined element.itrogen is a common element in the universe, estimated at about seventh in total abundance in the Milky Way and the Solar System.
