Locate the pair of switches.
In this experiment, as in the previous ones, five pairs of MEPs were simultaneously recorded from the two hand muscles ("Basal").
The experimental procedure was as follows: pairs of MEPs were recorded from FDI and ADM muscles as a control ("Basal").
Pairs of MEPs from the two muscles were recorded in each experimental condition, each TMS pulse being spaced 10 15 seconds from the previous one.
Five pairs of MEPs (out of the 7 8 acquired for each condition) were finally stored for further analysis in each experimental condition.
In each of these four conditions, pairs of MEPs were recorded from both muscles.
Pairs of MEPs were recorded from FDI and ADM muscles (condition "Basal-1"), without giving particular instructions to subjects.
Pairs of MEPs were recorded duirng each of these four conditions ("Salame", "Mortadella", Bombolone, "Soap"), whose order was randomized.
After all conditions were run, five additional pairs of MEPs were recorded ("Basal-2") in order to verify that corticospinal excitability remained stable also in the absence of visual or olfactory stimulation.
Then, pairs of MEPs were recorded for each of seven -randomly administered- sniffing conditions, including five standardised synthetic odorants (Sniffin sticks olfactory test) [47], routinely used for diagnosis in hyposmic and anosmic patients, plus two natural odorants ("Coffee" in beans and "Mortadella", a typical Italian pork-derived product to make sandwiches, or "balony").
The paper alleged the pair and Romanian MEP Adrian Severin accepted offers of cash in exchange for influencing laws.
