An automatic experimental apparatus to study arm reaching in New World monkeys.

Journal Article (Journal Article)

BACKGROUND: Several species of the New World monkeys have been used as experimental models in biomedical and neurophysiological research. However, a method for controlled arm reaching tasks has not been developed for these species. NEW METHOD: We have developed a fully automated, pneumatically driven, portable, and reconfigurable experimental apparatus for arm-reaching tasks suitable for these small primates. RESULTS: We have utilized the apparatus to train two owl monkeys in a visually-cued arm-reaching task. Analysis of neural recordings demonstrates directional tuning of the M1 neurons. COMPARISON WITH EXISTING METHOD(S): Our apparatus allows automated control, freeing the experimenter from manual experiments. CONCLUSION: The presented apparatus provides a valuable tool for conducting neurophysiological research on New World monkeys.
