This paper presents a theoretical reframing of journalism as fundamentally mobile practice and outlines research agenda for studying the politics mobility in that is centered on everyday work journalists. Our draws geographer Tim Cresswell’s six components mobility, which are motive force, speed, rhythm, route, experience, friction (Cresswell, T. 2010. “Towards Politics Mobility.” Environment P...

The main aim of this study was to test whether the use of rhythmic information to induce temporal expectations can overcome the deficit in controlled temporal preparation shown by patients with frontal damage (i.e. temporal orienting and foreperiod effects). Two tasks were administered to a group of 15 patients with a frontal brain lesion and a group of 15 matched control subjects: a Symbolic C...

A fast, coherent EEG rhythm, called a gamma or a '40 Hz' rhythm, has been implicated both in higher brain functions, such as the 'binding' of features that are detected by sensory cortices into perceived objects, and in lower level processes, such as the phase coding of neuronal activity. Computer simulations of several parts of the brain suggest that gamma rhythms can be generated by pools of ...

Human scalp electroencephalographic rhythms, indicative of cortical population synchrony, have long been posited to reflect cognitive processing. Although numerous studies employing simultaneous thalamic and cortical electrode recording in nonhuman animals have explored the role of the thalamus in the modulation of cortical rhythms, direct evidence for thalamocortical modulation in human has no...

are often seen and make interpretation more difficult. Some are not understood on the basis of physiology and clinical implication. For others, no pathological substrate or epileptic condition explains these patterns. Background activity refers to the EEG rhythm corresponding to the patient’s age and state of consciousness. The alpha rhythm is in the range of 8 to 12 Hertz (Hz), has a sinusoida...

Whole-genome sequencing of bacteria and advances in bioinformatics have revolutionized the vaccinology field, leading to the identification of potential vaccine candidates without the need for cultivating the pathogen. This approach, termed "reverse vaccinology", reduces the time and cost required for the identification of candidate vaccines and provides new solutions for those diseases for whi...

Neuronal oscillations in the gamma band (30-80 Hz) have been suggested to play a central role in feature binding or establishing channels for neural communication. For these functions, the gamma rhythm frequency must be consistent across neural assemblies encoding the features of a stimulus. Here we test the dependence of gamma frequency on stimulus contrast in V1 cortex of awake behaving macaq...

Slow spike and wave discharges (0.5-4 Hz) are a feature of many epilepsies. They are linked to pathology of the thalamocortical axis and a thalamic mechanism has been elegantly described. Here we present evidence for a separate generator in local circuits of associational areas of neocortex manifest from a background, sleep-associated delta rhythm in rat. Loss of tonic neuromodulatory excitatio...
