A statistical approach to the inverse problem in magnetoencephalography
, 2014 Magnetoencephalography (MEG) is an imaging technique used to measure the magnetic field outside the human head produced by the electrical activity inside the brain.

Non-Conscious Brain Processes Revealed by Magnetoencephalography (MEG) [PDF]
, 2011 Information processing in the human brain can happen fully conscious or in total absence of consciousness. Despite being far away from understanding consciousness in terms of being a subjective phenomenon based on neural activity we can at least imagine what it means to be consciously aware of a sensory perception or knowledge or ourselves. At the very

Uncovering the impact of the cardiovascular system on cerebrovascular health using MRI
Experimental Physiology, EarlyView.Abstract Human cerebrovasculature is finely tuned to enable local changes in blood flow to meet the brain's demands, whilst protecting the brain from systemic changes in blood pressure, both acutely during a heartbeat and chronically over time. This review summarises cerebrovascular structure and function, their role in disease and neurodegeneration ...

A magnetoencefalografia. Aplicações Clínicas.
Acta Médica Portuguesa, 2004 Magnetoencephalography (MEG) is a technique that enables the measurement of the magnetic fields produced by the brain. It is a noninvasive method that allows, similarly to electroencephalography (EEG), to follow the evolution of electrophysiological ...

Experimental Physiology, EarlyView.Abstract Cerebral blood flow (CBF) is essential for sustaining neuronal metabolism and cognitive performance; however, the precise relationship between perfusion and cognition remains unclear. Although ageing and disease are associated with progressive declines in CBF and cognitive impairment, the acute effects of altered CBF under environmental ...

Experimental Physiology, EarlyView.Abstract figure There is positive covariation in the amplitudes of motor evoked potentials (MEPs) generated by (near simultaneous) stimulation of the two motor cortices. That is, larger responses to stimulation of the left motor cortex tend to be accompanied by larger responses to stimulation of the right motor cortex, and smaller responses to ...

Distinctive neurophysiological correlates of sound onset and offset perception in humans
The Journal of Physiology, EarlyView.Abstract figure legend Electroencephalography (EEG) recordings were obtained from participants listening to successive pairs of 1‐2 s noises in a silent background (Study 1) or successive pairs 1‐2 s silent gaps in a noise background (Study 2). Participants heard the same stimuli in the context of either a duration discrimination task (identifying ...
