Cortical current density estimation for the classification of motor imagery
Classification of motor imagery by means of cortical current density estimation and Von Neumann entropy.
J Neural Eng. 2007 Jun;4(2):17-25
Authors: Kamousi B, Amini AN, He B
The goal of the present study is to employ the source imaging methods such as cortical current density estimation for the classification of left- and right-hand motor imagery tasks, which may be used for brain-computer interface (BCI) applications. The scalp recorded EEG was first preprocessed by surface Laplacian filtering, time-frequency filtering, noise normalization and independent component analysis. Then the cortical imaging technique was used to solve the EEG inverse problem. Cortical current density distributions of left and right trials were classified from each other by exploiting the concept of Von Neumann entropy. The proposed method was tested on three human subjects (180 trials each) and a maximum accuracy of 91.5% and an average accuracy of 88% were obtained. The present results confirm the hypothesis that source analysis methods may improve accuracy for classification of motor imagery tasks. The present promising results using source analysis for classification of motor imagery enhances our ability of performing source analysis from single trial EEG data recorded on the scalp, and may have applications to improved BCI systems.

Summer school on Presence
The First PEACH Summer School: 4-6th July 2007, Santorini Greece
"Towards Human Machine Confluence - Presence Technologies and Foundations"
Are you a PRESENCE researcher or PhD student? Are you looking to find out more about the latest presence research, methodologies and technologies? If so then the first PEACH Summer School is for you.
Registration deadline: 20th April 2007
PEACH is a FP6 Coordination Action on Presence. Its objective is to stimulate structure and support the Presence research community, with special attention to the challenges associated with the interdisciplinary character of the field, and to produce visions and roadmaps to support the construction of the Presence ERA. The Summer School is the ideal place to join the leaders in the field for a series of lectures and presentations. There are also working groups, which will focus on the latest technologies, applications and measurement techniques along with a poster session where you can present your work to other attendees and experts.
