CSU HES 319 Lab - Neuromuscular Aspects

Prototype pilot testing underway for an inexpensive, simple and accessible device for increasing the precision and repeatability of tendon taps for the stretch reflex lab. Precise adjustability of the tap intensity. 

We like it when students are prepared! Yes, Dr. T just might sneak up on you at the gym.

Can you override external electrical signals with your own voluntary command? These students pilot tested their professor and enjoyed his difficulty perhaps a little too much. It’s all good fun.

Over 22 years of observing these responses in vast numbers of students, and this is the most excitable spinal cord tonic vibration reflex we have ever seen. Thank you Azalea for being a willing participant!
Just to be clear, this is the smallest amplitude, very high frequency, vibration that you can imagine, which is causing the stretch reflex circuit to become extremely active, extremely rapidly. Still a mystery as to why some students have very large responses, and others don’t.

Remarkably sensitive tonic vibration reflex in this particular student. We see a great range of responses.

A pretty remarkable week in the teaching lab The question is, was Dr. Tracy more excited than Azalea‘s spinal cord, or the other way around?
Tonic vibration reflex lab sometimes produces some unique and fun learning opportunities. The responses you see here are probably 1/500 people.
