With this lab, however, we are skipping ahead to the topic of sensory systems, which we will not get to in lecture until the end of the course. �� The utility and versatility of the cockroach for instruction and demonstration of nervous activity makes this an attractive model for use in undergraduate neuroscience laboratory courses. Extracellular Recoding Traces of a Cockroach Tibia Somatosensory System Introduction The purpose of this experiment is to study the action potentials in the cockroach somatosensory system using extracellular recording. The brain and spinal cord receives signal from organs of peripheral nervous system and dictates course of action in responses to stimulus. In this lab, the frog will have been anesthetized, sacrificed, and double pithed (both its brain and spinal cord will have been destroyed). A secondary purpose is to provide students with the opportunity to carefully observe and work with an insect they normally find offensive. To Dissect the Sciatic Nerve PLAY.

Literature. tibial spines. Observe the phenomenon of sensory adaptation, in which the response to a prolonged stimulus decreases over time. The work, reported May 31 in Science , is a step toward creating artificial skin for prosthetic limbs, to restore sensation to amputees and, perhaps, one day give robots some type of reflex capability. These neurons take in information and translate it to an electrical signal that gets sent to the central nervous system, much like the spikes you hear when doing the cockroach leg experiments. This rudimentary artificial nerve circuit integrates three previously described components.
