Aim of study (acc. to author)

To study the effect of acute exposure to ultra wideband (UWB) electromagnetic fields on the Primate Equilibrium Platform (PEP) task, where the monkey's task is to manipulate a joystick control to compensate for the random perturbations in the pitch plane that are generated by a computer at unpredictable intervals.
