A Laboratory Method to Measure Contagious Yawning in Rats

Our protocol is significant because it provides an easy way to investigate which senses may be involved in contagious yawning in rats. The use of a non-invasive procedure and the availability of the application software, which speeds the calculation for measuring contagious yawning, are the main advantages of this technique. Individuals who have never performed this technique shouldn't face major difficulties in the implementation, provided they methodically follow each step and seek professional advice when constructing the observation case.

Visual demonstration of this method aids in understanding the spatial arrangement of the observation cages during the experiment. Helping to avoid errors in designation of the treatments. Demonstrating that procedure will be Evelyn Beristain-Castillo, a postdoc from my lab.
