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 ...

Frontiers in Neuroscience, 2019 Previous neuroimaging studies have shown that sounds can be discriminated due to living-related or man-made-related characteristics and involve different brain regions. However, these studies have mainly provided source space analyses, which offer simple

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 ...

Frontiers in Human Neuroscience, 2018 Letter-speech sound (LSS) integration is crucial for initial stages of reading acquisition. However, the relationship between cortical organization for supporting LSS integration, including unimodal and multimodal processes, and reading skills in early ...

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 ...

Optically pumped magnetoencephalography in epilepsy
Annals of Clinical and Translational Neurology, 2019 We demonstrate the first use of Optically Pumped Magnetoencephalography (OP‐MEG) in an epilepsy patient with unrestricted head movement. Current clinical MEG uses a traditional SQUID system, where sensors are cryogenically cooled and housed in a helmet ...

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 ...

Psychiatric Research and Clinical Practice, EarlyView.Objective Suicide has been linked to distinct impairments in emotional face processing. This magnetoencephalography (MEG) study used a multimodal design to address how cortisol dysregulation, often reported in individuals with suicidal thoughts and behaviors, affects emotional face processing.

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.
