28 Dec 1999 | Subject: | Data Analysis, Statistics and Probability; Medical Physics | physics.data-an physics.med-ph q-bio | Abstract: | We present a new wavelet based method for the denoising of {it event related potentials} ERPs), employing techniques recently developed for the paradigm of deterministic chaotic systems. The denoising scheme has been constructed to be appropriate for short and transient time sequences using circular state space embedding. Its effectiveness was successfully tested on simulated signals as well as on ERPs recorded from within a human brain. The method enables the study of individual ERPs against strong ongoing brain electrical activity. | Source: | arXiv, physics/0001069 | Services: | Forum | Review | PDF | Favorites |
