1. Black Lives, White Quotation Marks : Textual Constructions of Selfhood in South African Multivoiced Life Writing
Abstract : This thesis focuses on South African multivoiced and collaborative life writing. The analysed primary texts are The Long Journey of Poppie Nongena (1980) by Elsa Joubert, The Calling of Katie Makanya: A Memoir of South Africa (1995) by Margaret McCord, Finding Mr Madini (1999) by Jonathan Morgan and the Great African Spiderwriters, David’s Story (2000) by Zoë Wicomb, and There Was This Goat: Investigating the Truth Commission Testimony of Notrose Nobomvu Konile (2009), co-written by Antjie Krog, Nosisi Mpolweni and Kopano Ratele.

2. Defense-related inhibition of sympathetic nerve activity: Insights from neuroimaging and monozygotic twins on related cortical processes and clinical potential
Abstract : This thesis investigates a physiological phenomenon observed in the peripheral sympathetic nervous system in response to various stressors and tries to bring it closer to clinical research. Sudden surprising stimulation can evoke a transient inhibition of sympathetic nerve activity to blood vessels in the human body which is also predictive of the blood pressure response. READ MORE

3. Investigations of human cortical processing of gentle touch. A study with time-resolved electro-magnetic signal analysis
Abstract : The present work summarizes investigations of the temporal correlates of brain activity elicited by gentle, moving touch on the hairy skin in healthy participants and in epilepsy patients. Light touch to the hairy skin activates two distinct afferent classes: fast conducting, Aβ afferents and slowly conducting C-tactile (CT) afferents. READ MORE

4. On Neuromagnetic Assessment of the Contingent Negative Variation
Abstract : The contingent negative variation, CNV, is a cognitive process related to anticipation and motor preparation. In the present work the CNV was studied by the use of magnetoencephalography, MEG. READ MORE

5. High-temperature superconducting magnetometers for on-scalp MEG
Abstract : In the growing field of on-scalp magnetoencephalography (MEG), brain activity is studied by non-invasively mapping the magnetic fields generated by neuronal currents with sensors that are flexibly placed in close proximity to the subject's head. This thesis focuses on high-temperature superconducting magnetometers made from YBa2Cu3Ox-7 (YBCO), which enables a reduction in the sensor-to-room temperature standoff distance from roughly 2 cm (for conventional MEG systems) down to 1 mm.
