Does anyone know how to work with Motor Evoked Potentials (MEPs)?

Fri, 17 Nov 2017 17:02:28 GMTDear all,

I am working for the first time with Transcranial Magnetic Stimulation and Motor Evoked Potentials (MEPs). I am recording MEPs' amplitude as the peak-to-peak value. But does anyone know hot to normalize raw MEPs? Somewhere I read z-score, somewhere that is needed a logarithm (but how can I choose the right base?). I can really understand anything about it.

P.S. I must say that I am really new to statistics.

The model studies how a shock on one variable affects a second variable. I understand that if the first month's response is +3 %, it means that the initial value of the response variable increases by 3 percent following a shock. However, I'm uncertain on how to interpret the second month. If the value for the second month is +2%, is the accumulated effect 1,03*1,02 = approx. 5 % increase from the initial value? Or does this mean that the initial response falls from 3 % to 2 % in the second month, leaving the overall effect at 2%?

Thanks.

Thu, 16 Nov 2017 20:02:57 GMTHello everyone

I need some help confirming what kind of stats tests to run on some data I've collected.

I'm looking at three different vegetation communities within a reserve. I have carried out a 10 metre transect in each veg community, noting every species along the way. Furthermore, I 'sheeted' and thus collected insects in each reserve as well and identified their morpho type.

I am to determine if there is a significant different in insect morpho types between the three communities.

What stats tests should I use?

James
