Abstract

Evoked response potentials provide insight into spatio-temporal dynamics of brain electrical activity. The activity is much easier to perceive using an animated 3D visualization. In addition to already established visual and auditory evoked responses, we are using Trivector NeuroScan (TVR) for quantitative analysis of neurological activity as well as a scalar assessment of neurological cognitive deficits without the conscious participation of the subject. In this paper we present the development environment TempoEP for visualization of evoked EEG scalp potentials and animation of the signal sources of evoked response potentials on transparent 3D head model.
