This paper presents an overview of the fundamentals and state of the-art in noninvasive physiological monitoring instrumentation with a focus on electrode and optrode interfaces to the body, and micropower-integrated circuit design for unobtrusive wearable applications. Since the electrode/optrode-body interface is a performance limiting factor in(More)
In this paper we use a closed-loop force feedback system to investigate the effect of altering proprioceptive feedback on EEG and resting tremor in Parkinson's Disease. A velocity dependent counterforce simulating viscous friction was provided by haptic robots with simultaneous recording of kinematics, EMG and EEG while a patient was on and off dopaminergic(More)
A potential for detecting high gamma band (HGB) activity from scalp EEG is explored by employing a high input-impedance electroencephalograph for the measurement. An anti-saccade task was designed to elicit motor-related HGB activity. As a result, we confirmed increased power of HGB (100-105 Hz) preceding the anti-saccade initiation in all three subjects.

Visual evoked potentials (VEP) are used to confirm the function of prosthetic devices designed to stimulate retinas with damaged photoreceptors in vivo. In this work, we focus on methods and experimental consideration for recording visual evoked potential in rabbit models and assesses the use for retinal prosthesis research. We compare both invasive and(More)
