Abnormal salience signaling in schizophrenia: The role of integrative beta oscillations
(2016)Aberrant salience attribution and cerebral dysconnectivity both have strong evidential support as core dysfunctions in schizophrenia. Aberrant salience arising from an excess of dopamine activity has been implicated in ... -
Abnormal visuomotor processing in schizophrenia
(2016)Subtle disturbances of visual and motor function are known features of schizophrenia and can greatly impact quality of life; however, few studies investigate these abnormalities using simple visuomotor stimuli. In healthy ... -
Altered temporal stability in dynamic neural networks underlies connectivity changes in neurodevelopment
(2018)Network connectivity is an integral feature of human brain function, and characterising its maturational trajectory is a critical step towards understanding healthy and atypical neurodevelopment. Here, we used magnetoenc ... -
Changes in electrophysiological markers of cognitive control after administration of galantamine
(2018)The healthy brain is able to maintain a stable balance between bottom-up sensory processing and top-down cognitive control. The neurotransmitter acetylcholine plays a substantial role in this. Disruption of this balance ... -
Complexity measures in magnetoencephalography: Measuring "disorder" in schizophrenia
(2015)This paper details a methodology which, when applied to magnetoencephalography (MEG) data, is capable of measuring the spatio-temporal dynamics of 'disorder' in the human brain. Our method, which is based upon signal ... -
Development of human electrophysiological brain networks
(2018)Functional activity in the human brain is intrinsically organized into independently active, connected brain regions. These networks include sensorimotor systems, as well as higher-order cognitive networks such as the ... -
Motor-related oscillatory activity in schizophrenia according to phase of illness and clinical symptom severity
(2020)Magnetoencephalography (MEG) measures magnetic fields generated by synchronised neural current flow and provides direct inference on brain electrophysiology and connectivity, with high spatial and temporal resolution. The ...
