1. Nerve Conduction
In this lab you will learn about how a reflex controlled by sensory and motor neurons is affected by different conditions. You will explore the effects of coffee, an energy drink, alcohol, local anesthesia and sleep deprivation on the neurons controlling the pin prick reflex. Using simulated timers, you will record the time (in milliseconds) it takes for the nerve impulse to travel along the sensory and motor neurons during a pin prick test. Repeating the pin prick stimulus will allow you to conduct multiple trials for each condition. Once data is collected, you can describe the effects of each condition on nerve conduction time.
