New students … same old rats

Just a short post to introduce you to some of the “newer” students in the Bonnan Lab: Kelsey Gamble and Caleb Bayewu.

Today we were working with some Sprague-Dawley rats to track how much their forelimb is abducted at the elbow (pulled away from the side of the body) during locomotion.  We use an apparatus called the OptiTrack V120 which consists of 3 integrated infrared cameras that send out rapid pulses of IR light.  The rats wear a vest with two markers on the back which gives us the position of their body’s mid-line, and another small marker is affixed to their elbow (with the equivalent of eyelash glue) … with tender loving care, of course.

Peter the rat was more interested in exploring the lab than being measured for science.

You know you’re a scientist when after months of trial and error and fiddling with the equipment, we literally jumped for joy today when we successfully recorded all five walking trials!  Why are we doing this?  Stay tuned …
