First background noise is removed from the signals. The remaining signals are a superposition of spike trains which are subsequently assigned to different families. For this two techniques are used: classic PCA and code vectors. Both techniques confirm that amplitude is the distinguishing feature of spikes. Finally the presence of various types of periodicity in spike trains are examined using correlation and the interval shift histogram. The results allow the development of a visual aid for surgeons. date: 2008 type: Study Group Report type: NonPeerReviewed format: application/pdf language: en identifier: http://miis.maths.ox.ac.uk/miis/266/1/philips_amc.pdf format: application/pdf language: en identifier: http://miis.maths.ox.ac.uk/miis/266/2/philips_ams-report.pdf identifier: Archer, Claude and Hochstenbach, Michiel and Hoede, Kees and Meinsma, Gjerrit and Meijer, Hil and Ali Salah, Albert and Stolk, Chris and Swist, Tomasz and Zyprych, Joanna (2008) Neural spike sorting with spatio-temporal features.
