11. High-Tc SQUIDs for biomedical applications: immunoassays, MEG, and ULF-MRI
Abstract : This thesis describes high transition temperature superconducting quantum interference devices (high-Tc SQUIDs) for magnetic immunoassays (MIAs), magnetoencephalography (MEG) and ultra-low field magnetic resonance imaging (ULF-MRI).High-Tc dc SQUID sensors were fabricated in single layers of YBa2Cu3O7−δ deposited by pulsed laser deposition and patterned using photolithography on 10×10 mm2 SrTiO3 bicrystal substrates.

12. Fabrication and noise properties of high-Tc SQUIDs with multilayer superconducting flux transformers
Abstract : The thesis describes the development of highTc superconducting quantum interference devices (SQUIDs) with multilayer thin film flux transformers. High-Tc SQUID magnetometers are promising in various biomedical applications, including magnetoencephalography (MEG) and ultra-low field magnetic resonance imaging (ulf-MRI). READ MORE

13. Objective diagnostics of tinnitus
Abstract : Background Tinnitus is the phantom perception of sound reported by around 14% of the population. For over 120 million people worldwide tinnitus is perceived as a major problem. Still, tinnitus is a heterogenous condition with no stratified sub-types or biomarkers for objective assessment. READ MORE

14. Cortical plasticity in response to median nerve trauma
Abstract : Median nerve injuries in adults, repaired with nerve suture, lead to incomplete functional recovery despite improved surgical technique. This results in a reduction in quality of life, poorer working ability and a considerable expense for society. Misrouting of axons at the suture site connects regenerating axons to the wrong distal end organs. READ MORE

15. Tracking selective attention in a musical cocktail
Abstract : The cocktail party effect refers to mankind’s ability to focus attention on a single sound within noisy or complex auditory environments, in order to extract the most behaviourally-relevant information present. To investigate this cognitive phenomenon in a precise manner, we used frequency-tagging to separate neural auditory steady-state responses (ASSRs), which are specific to the driving frequency of each auditory source, from a neural mix elicited by multiple simultaneous stimuli.
