Correlated amplitudes of potentials evoked in homologous muscles by magnetic stimulation reveal positive covariation of corticospinal output

open access: yesExperimental 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 ...

Changes in the cortical GABAergic inhibitory system with ageing and ageing‐related neurodegenerative diseases

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend With ageing and age‐related neurodegenerative diseases, the amount of GABA and GABAergic inhibition as well as the modulation (indicated by sine wave) of GABAergic inhibition is reduced, whereas excitation is increased. In many parts of the brain, this leads to a mismatch of facilitatory (green neurons) and inhibitory (red ...

Neuromuscular mechanisms for the fast decline in rate of force development with muscle disuse – a narrative review

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Muscle unloading induces declines in muscle function, particularly in maximal and explosive strength. The decline in explosive strength (quantified as rate of force development, RFD) is greater than the decline in maximal strength (quantified as maximal force, Fmax).

Human brain imaging with high‐density electroencephalography: Techniques and applications

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Recent technological advances have elevated high‐density electroencephalography (hdEEG) to the status of a reliable neuroimaging tool. This technique measures scalp potentials with high temporal resolution, which permits the non‐invasive detection and analysis of neural oscillations.

The ageing brain: Cortical overactivation – How does it evolve?

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Age‐related progression of brain activity over time. This review article proposes a developmental process in the ageing brain, from compensation to negative overcompensation to chronic maladaptive overcompensation, which leads to dedifferentiation and desegregation.
