EMG Lab

Logger pro is freeeeaaaky!  And I think it hates me because it won't let me do what I want.  And I can't take screenshots on the mac because it sucks too.  Unfortunately this blog shall not have the pictures of Seth's diagrams from eating food but I'll describe them!
In this lab we hooked Seth up to a computer, attaching electrodes to the top and bottom of his jaw muscle.  We did this so we could measure the activity of his muscle while he ate.  Different foods displayed more activity, narrower wavelengths and higher altitudes, than others.  Things like the marshmallow and poptart required more activity out of his jaw muscle than things like gatorade and bananas.   Every time Seth chewed on something it sent recordable impulses to the electrodes and we were able to see the measurements on our graph.  When the lines were higher and closer together it meant that Seth was taking more work to eat the item.  When he drank the gatorade the line was practically flat, just little bumps going along it.  I've been told that we'll learn more about what this means next semester.  I look forward to the enlightening!!
