P 116 Methylphendiate effects on the coupling between attentional processes and motor cortex excitability

Event related potentials (ERPs) allow the examination of sensory, attentional and cognitive processes occurring as brain responses to stimuli while the excitability of motor pathways can be evaluated by transcranial magnetic stimulation (TMS).The interplay between both, attentional processes and motor cortex excitability has been rarely reported in the literature. So far, only two studies used ERP and TMS in combination, focused on inhibition processes and reported compensatory cognitive mechanisms in case of measurement of reduced activation of inhibitory intracortical interneurons in the motor cortex (Heinrich et al., 2014; Hoegl et al., 2011).
