The diagnosis of a secondary headache is made if the underlying disease is thought to cause headache or if a close temporal relationship is present together with the occurrence of the headache. At first glance, this may allow clearly secondary headaches to be distinguished from primary headaches. However, by reviewing the available literature concerning several selected secondary headaches, we will discuss the hypothesis that some secondary headaches can also be understood as a variation of primary headaches in the sense that the underlying cause (e.g. infusion of glyceryl trinitrate [ICHD-II 8.1.1], epilepsy [7.6.2], brain tumours [7.4], craniotomy [5.7], etc.) triggers the same neurophysiologic mechanisms that are responsible for the pain in primary headache attacks.","address":"","school":"","issn":"1129-2377","doi":"10.1007\/s10194-012-0443-8","isi":"","pubmed":"22466226","key":"Schankin2012","howpublished":"","urllink":"","refid":23,"weight":23}

The by far most influential fMRI technique is based on a local T2*-sensitive hemodynamic response to neuronal activation, also known as the blood oxygenation level dependent or BOLD effect. Consequently, the term 'fMRI' is often used synonymously with BOLD imaging. Because interpretations of fMRI brain activation maps often appear intuitive and compelling, the reader might be tempted not to critically question the fundamental processes and assumptions. We review some essential processes and assumptions of BOLD fMRI and discuss related confounds and pitfalls in fMRI - from the underlying physiological effect, to data acquisition, data analysis and the interpretation of the results including clinical fMRI. A background framework is provided for the systematic and critical interpretation of fMRI results.","address":"","school":"","issn":"1432-1084","doi":"10.1007\/s00330-009-1456-9","isi":"","pubmed":"19504107","key":"Haller2009","howpublished":"","urllink":"","refid":25}

Classical computing, which previously faced such issues, currently relies on silicon chips hosting billions of fin field-effect transistors. These devices are small enough for quantum applications: at low temperatures, an electron or hole trapped under the gate can serve as a spin qubit. Such an approach potentially allows the quantum hardware and its classical control electronics to be integrated on the same chip. However, this requires qubit operation at temperatures above 1\u2009K, where the cooling overcomes heat dissipation. Here we show that silicon fin field-effect transistors can host spin qubits operating above 4\u2009K. We achieve fast electrical control of hole spins with driving frequencies up to 150\u2009MHz, single-qubit gate fidelities at the fault-tolerance threshold and a Rabi-oscillation quality factor greater than 87. Our devices feature both industry compatibility and quality, and are fabricated in a flexible and agile way that should accelerate further development.","note":"","tags":"","weight":676,"removeattachment":"on"}
