Estimation of Neural Dynamics in Brain-Machine Systems

Abstract

The closed-loop interaction of neural tissue with simulated or actual physical devices provides means for assessing critical features of neural dynamics. I will report the results of experiments in which in vitro preparation from the lamprey�s brainstem is in a closed-loop interaction with simulated dynamical devices of different orders. I obtained stable measures of the dynamical dimension of the neural preparations by subtracting the known dimension of the device from the estimated dimension of the compound brain-machine system. The results show the presence of significant dynamical components in a simple interaction with the neural tissue.
