Question

Quizplus · Accepted Answer

Studies on classical conditioning of the immune system have demonstrated that a neutral stimulus can become a conditioned stimulus (CS) that weakens immune system activity, such as in cases of stress-related immune suppression. However, a neutral stimulus can also become a CS that strengthens immune system activity, as seen in conditioned immunomodulation. Additionally, presentation of a CS can increase the activity of natural killer cells, a type of immune cell involved in detecting and destroying infected or cancerous cells. Therefore, all of the options (A, B, and C) are correct.
