Torres, David J.; Romero, Andres; Colgan, Wes, III; Ricoy, Ulises M. – Advances in Physiology Education, 2021
Undergraduates use a spike sorting routine developed in Octave to analyze the spiking activity generated from mechanical stimulation of spines of cockroach legs with the inexpensive SpikerBox amplifier and the free software Audacity. Students learn the procedures involved in handling the cockroaches and recording extracellular action potentials…

Truong, Thai Phat; Bailey, Sophia J.; Golliher, Alexandra E.; Monroy, Erika Y.; Shrestha, Uttar K.; Maio, William A. – Journal of Chemical Education, 2018
The ability of certain organometallic reagents to react via 1,2- or 1,4-addition to an a,ß-unsaturated ketone is a fundamental example of regioselectivity at the second-year undergraduate organic level. The following two experiments were designed to demonstrate this preference by exploiting carvone as an inexpensive chiral, nonracemic substrate.…
