Detection And Removal Of Eyeblink Artifacts From Eeg Using Wavelet Analysis And Independent Component Analysis, Jimy Pesin
Theses
Electrical signals generated by brain activity that are measured by the electroencephalogram can be distorted by electrical activity originating from eyeblinks and eye movements. This thesis proposes a new technique to identify and remove eyeblink artifacts from EEG data. An algorithm using a combination of wavelet analysis and independent component analysis (ICA) is implemented to detect the temporal location of the eyeblink artifact and eliminate it without compromising the integrity of the primary EEG data. The discrete wavelet transform is performed on 10 second epochs of data to detect the occurrence of ocular artifact. ICA is used to separate out …

The Primary Objective of this research is to implement an automatic method for selecting the most optimal EEG channels for task classification purposes. The secondary objective of this research is to choose the most optimal EEG rhythm from which the optimal EEG channels would be selected automatically. The automatic selection of the optimal channels is enabled by implementing the Common Spatial Patterns algorithm (CSP). Common spatial analysis is performed on the data recorded. By choosing the channels with high spatial pattern values the optimal channels are chosen. The optimal frequency bands are chosen by splitting the data from a single …

Clinical Features, Eeg Findings And Outcome In Patients With Bilateral Periventricular Nodular Heterotopia And Epilepsy, Aysun Ünal, Serap Saygi
Turkish Journal of Medical Sciences
Aim: To review the clinical, electrophysiological and neuroimaging data of eight adult patients (4F/4M) with epilepsy and bilateral periventricular nodular heterotopia (PNH) after a long duration of follow-up. Materials and Methods: The clinical charts were reviewed for demographic and clinical features, seizure types and frequency, treatment and prognosis of all eight patients who were under follow-up by one of the authors (SS). The recordings of video-EEG monitoring with scalp electrodes in five patients and routine EEGs in all patients were reviewed. Results: The clinical semiology was in accord with seizures originating from temporal lobe region in four patients, while an …
Neuroimaging And The "Complexity" Of Capital Punishment, O. Carter Snead
Neuroimaging And The "Complexity" Of Capital Punishment, O. Carter Snead
Journal Articles
The growing use of brain imaging technology to explore the causes of morally, socially, and legally relevant behavior is the subject of much discussion and controversy in both scholarly and popular circles. From the efforts of cognitive neuroscientists in the courtroom and the public square, the contours of a project to transform capital sentencing both in principle and in practice have emerged. In the short term, these scientists seek to play a role in the process of capital sentencing by serving as mitigation experts for defendants, invoking neuroimaging research on the roots of criminal violence to support their arguments. Over …
