How does modulation of the activity of an afferent neuron lead to increase in MEP's?

I was confused reading this: Another example has been described with the primary motor cortex, where the afferent axonal synaptic input (Figure 1) can be facilitated by anodal tDCS (Rahman et ...

Recording motor-evoked potentials (MEPs) in response to transcranial direct current stimulation (tDCS)?

The amplitudes of motor-evoked potentials (MEPs) are often recorded as a measure of (change in) cortical excitability, after administering some form of non-invasive brain stimulation (NIBS). In a ...

Why does cathodal tDCS (negative) produce sensation, while anodal tDCS (positive) does not?

If neurons fire due to an intracellular influx of positive ions, why are the negative electrodes in tDCS felt more strongly than the others? For example, see "Reducing Procedural Pain and Discomfort ...
