Gascoyne L, Brookes M, Rathnaiah M, Ul Haq Katshu M, Koelewijn L, Williams G, et al.
Neuroimage Clin . 2020 Dec; 29:102524. PMID: 33340975
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 movement-related beta decrease...

NMR Biomed . 2020 Nov; 34(2):e4440. PMID: 33140530
The present work aims to show the applicability of an analytical model for the optimisation of the STEAM sequence timing parameters for lactate detection at ultra high-field. The effects of...

Carradus A, Mougin O, Hunt B, Tewarie P, Geades N, Morris P, et al.
Neurobiol Aging . 2020 Oct; 96:246-254. PMID: 33049517
We have used the magnetisation transfer (MT) MRI measure as a primary measure of myelination in both the gray matter (GM) of the 78 cortical automated anatomical labeling (AAL) regions...

J Magn Reson . 2020 Feb; 312:106686. PMID: 32006793
Spin-exchange optical pumping (SEOP) can enhance the NMR sensitivity of noble gases by up to five orders of magnitude at Tesla-strength magnetic fields. SEOP-generated hyperpolarised (HP) Xe is a promising...

Fernandes C, Lanz B, Chen C, Morris P
NMR Biomed . 2020 Jan; 33(4):e4223. PMID: 31995265
Estimation of metabolic changes during neuronal activation represents a challenge for in vivo MRS, especially for metabolites with low concentration and signal overlap, such as lactate. In this work, we...

Seedat Z, Quinn A, Vidaurre D, Liuzzi L, Gascoyne L, Hunt B, et al.
Neuroimage . 2020 Jan; 209:116537. PMID: 31935517
Neural oscillations dominate electrophysiological measures of macroscopic brain activity and fluctuations in these rhythms offer an insightful window on cortical excitation, inhibition, and connectivity. However, in recent years the 'classical'...

Briley P, Liddle E, Groom M, Smith H, Morris P, Colclough G, et al.
J Neurophysiol . 2018 Oct; 120(6):3122-3130. PMID: 30354795
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 default...

Schizophr Bull . 2018 Sep; 45(4):883-891. PMID: 30239878
Introduction: Schizophrenia and schizotypal personality disorder (SPD) lie on a single spectrum of mental illness and converging evidence suggests similarities in the etiology of the 2 conditions. However, schizotypy is...

Gascoyne L, Mullinger K, Robson S, Kumar J, ONeill G, Palaniyappan L, et al.
Neuroimage Clin . 2018 Aug; 20:228-235. PMID: 30090697
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...

Neuroimage . 2018 Jul; 181:831-844. PMID: 29960087
The spatial topology of the human motor cortex has been well studied, particularly using functional Magnetic Resonance Imaging (fMRI) which allows spatial separation of haemodynamic responses arising from stimulation of...
