Nociceptive SSEPs induced using multisine frequency modulated pulse trains: An exploratory study in inducing multi-frequency SSEPs

Steady state evoked potentials (SSEPs) using multiple frequency inputs are a well-known method to study the underlying dynamics in the visual, auditory and somatosensory system. Multi-frequency SSEPs provide insight into system dynamics such as delay, non-linearities, and frequency response function. Despite extensive research, little is known...

Approximating Road Geometry with Multisine Signals for Driver Identification

The understanding of human responses to visual information in car driving tasks requires the use of system identification tools that put constraints on the design of data collection experiments. Most importantly, multisine perturbation signals are required, including a multisine road geometry, to separately identify the different driver...

An in situ spectro-electrochemical monitoring of aqueous effects on polymer/metal oxide interfaces

A spectro-electrochemical setup of Fourier transform infrared spectroscopy (FTIR) in the Kretschmann geometry and odd random phase multisine electrochemical impedance spectroscopy (ORP EIS) is applied to in situ monitor the effect of an aqueous electrolyte on the polymer/metal oxide interface. The interfacial interactions of an ultrathin...

The effect of perturbation properties on system identification of human balance control during stance

Introduction: System identification of the neuromuscular controller that regulates human balance, gives insight in the causes and effects of human balance disorders. The combination of varying perturbation properties in literature and lack of rationale behind chosen perturbation properties, reveals possible violations of assumptions made to...

Skirt Decomposition Method for the Identification of Linear Time-Varying Human Joint Admittance

Human joint admittance changes with numerous factors constituting the operational point. For large changes of the operational point, joint admittance can be identified using Linear Time-Varying methods on torque and angular<br/>position signals measured on human joints. Out of the available methods, the Skirt Decomposition method was selected...

Nonlinearity in the Light Processing of the Human Visual System

Visual evoked potentials, i.e responses to visual stimulation as recorded using electroencephalography have indicated the existence of nonlinear behavior of the visual pathway. Nonlinearities and time delay in the visual system play an important role in understanding the complex nature of the visual system. This study investigated the nonlinear...

Corticomuscular communication study by using current source density analysis

Corticomuscular communication during wrist motor tasks was investigated in this study. EEG signals from the sensorimotor cortex and EMG data from the reflexive carpi radialis and extensor carpi radialis muscles were recorded from five healthy subjects while performing visual-motor force tasks, with and without perturbation on the wrist....
