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?
Stimulator Settings Stimulus Duration: 0.2 ms Stimulus Voltage: 0.05 V Delay: 1 ms Rate: 1 Hz Mode: Repeat A sample display might look something like what you see to the right below. The Compound Action Potential is the second biphasic waveform, the Stimulus Artifact (explained below) appears first.It is important not to confuse the two! Note the Input Channels A and B ranges. By setting the A to D range, you change the A to D(hardware) gain, in order to more accurately view the CAP signal. sample display might look something like what you see to the right below. The Compound Action Potential is the second biphasic waveform, the Stimulus Artifact (explained below) appears first.
