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


ABSTRACT: 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.We have developed a fully automated, pneumatically driven, portable, and reconfigurable experimental apparatus for arm-reaching tasks suitable for these small primates.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.Our apparatus allows automated control, freeing the experimenter from manual experiments.The presented apparatus provides a valuable tool for conducting neurophysiological research on New World monkeys.
