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?

Delta sleep-inducing peptide (DSIP) is a naturally occurring substance, which was originally isolated from rabbit brain in 1977 [ ].This curious substance is a nonapeptide that is normally synthesized in the hypothalamus and targets multiple sites including some within the brainstem [ ].SIP is normally present in minute amounts in the blood. Brain and plasma DSIP concentrations exhibit a marked diurnal variation [ ] and there has been shown to be a correlation between DSIP plasma concentrations and circadian rhythm in human beings.
