Hey JedKampe, There are numerous drugs and conditions that can cause a false positive for cocaine not to mention human error. Substances that can cause a false positive drug test result: Amoxicillin is an antibiotic in the penicillin group of drugs. It fights bacteria in your body. Ampicillin is another antibiotic similar to amoxicillin.
When the nerve is damaged,the action potential remains between the electrodes and doesn't reach the second electrode (i.e potential difference remains positive and doesn't go into negative phase) , the biphasic action potential changes into monophasic action potential i.e with single phase. Source(s):E: biphasic action potential change into the monophasic action? Why does the biphasic action potential change into the monophasic action potential after nerve injury between the two recording electrodes?
In this laboratory, you will be recording an extracellular, biphasic, compound action potential. Clarifying those three terms in the context of the experiment will help you to understand and interpret your results.he nerve is made of thousands of axons whose size, myelination and position with respect to the stimulating and recording electrodes all affect the size of their contribution to the compound action potential. Both the classic intracellular action potential and the compound action potential are biphasic.
