Neuroscience Ocular Kinematics Measured by In Vitro Stimulation of the Cranial Nerves in the Turtle Maria Cano Garcia1, Steven C. Nesbit1, Chi C. Le2, James R. Dearworth Jr.1 1Department of Biology and Neuroscience Program, Lafayette College, 2Department of Information Technology, Computer Science, and Digital Media, Juniata College This protocol describes how to use an in vitro isolated turtle head preparation to measure the kinematics of their eye movements. After removal of the brain from the cranium, cranial nerves can be stimulated with currents to quantify rotations of the eye and changes in pupil sizes. Environment A Simple Approach to Manipulate Dissolved Oxygen for Animal Behavior Observations Christopher J. Grant1, Christopher J. McLimans1 1Department of Biology, Juniata College This article describes a simple and reproducible protocol to manipulate dissolved oxygen conditions in a laboratory setting for animal behavior studies. This protocol may be used in both teaching and research laboratory settings to evaluate organismal response of macroinvertebrates, fishes, or amphibians to changes in dissolved oxygen concentration.
