Frequency responses of human magnetophosphene perception thresholds during dark adaptation point to rod modulation

Experimental Physiology, EarlyView.
Abstract Magnetophosphenes are flickering lights perceived when an extremely low frequency magnetic field generates a sufficiently strong electric field in the head. Understanding how phosphenes are produced is crucial, as they form the basis for international safety standards and guidelines for both workers and the general population.

Isometric handgrip contraction increases tibialis anterior intrinsic motoneuron excitability in a dose‐dependent manner

Experimental Physiology, EarlyView.
Abstract The contribution of persistent inward currents (PICs) to motoneuron firing in the lower limb typically increases after a remote handgrip contraction, believed to result from diffuse serotonergic input increases in spinal cord. We investigated whether handgrip contraction intensity, duration and/or impulse would affect PIC estimates in tibialis

Use of transcutaneous spinal cord stimulation to explore inhibitory and facilitatory circuits in muscles of the human lower limb

Experimental Physiology, EarlyView.
Abstract The aim of this study was to explore the primary afferent depolarization mechanism, to determine whether the soleus transspinal evoked potential (TEP), elicited through transcutaneous spinal cord stimulation over the L1–L2 level, is modulated by presynaptic inhibition and heteronymous facilitation, similar to the Hoffmann (H) reflex, elicited ...

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

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 ...
