“…Contrary to that, Zhang et al (2007) found longer reaction times and greater incidence of commission errors in their MDD patients compared to control subjects. This divergence between our present data and the one by Zhang et al (2007) might be due to age effects and differences in the severity of depressive illness. The mean age of Zhang's patients was 68.7 ± 4.1 whereas the mean age of our patients was 40.1 ± 9.1.…”

“…Applying an auditory Go/Nogo task Kaiser et al (2003) showed a reduction of an early fronto-temporal positivity in the N2 time window in younger adult depressed patients (age: 40.0± 8.7) which was further corroborated by a recent study by Zhang et al (2007). In a group of patients with late-life depression (age ≥ 60 years) Zhang et al (2007) reported an enhanced (more negative) Nogo-N2 and a reduced (less positive) Nogo-P3 compared to healthy controls.…”

“…To the best of our knowledge there are only two ERP studies with adult depressed patients which applied a Go/Nogo task (Kaiser et al, 2003;Zhang et al, 2007). Derived from the study by Zhang et al (2007) and our own data from BPD patients (Ruchsow et al, 2007b) we expected reduced (less positive) Nogo-P3 amplitudes in MDD patients but not controls.…”

“…Derived from the study by Zhang et al (2007) and our own data from BPD patients (Ruchsow et al, 2007b) we expected reduced (less positive) Nogo-P3 amplitudes in MDD patients but not controls. With regard to the N2 component we predicted enhanced (more negative) Nogo-N2 amplitudes in MDD patients but not controls which is in accordance with the findings by Kaiser et al (2003) and Zhang et al (2007).…”

“…In a group of patients with late-life depression (age ≥ 60 years) Zhang et al (2007) reported an enhanced (more negative) Nogo-N2 and a reduced (less positive) Nogo-P3 compared to healthy controls. They interpreted this pattern as an inhibitory control deficit at an early frontal processing stage (Nogo-N2) which occupies more processing resources and hence increases the Nogo-N2, which in turn results in a burnout of the late-stage inhibitory process mirrored by the Nogo-P3 amplitude.…”

Theta oscillations within right dorsolateral prefrontal cortex contribute differently to speech versus limb inhibition

Evidence suggests that speech and limb movement inhibition are subserved by common neural mechanisms, particularly within the right prefrontal cortex. In a recent study, we found that cathodal stimulation of right dorsolateral prefrontal cortex (rDLPFC) differentially modulated P3 event‐related potentials for speech versus limb inhibition. In the present study, we further analyzed these data to examine the effects of cathodal high‐definition transcranial direct current stimulation (HD‐tDCS) over rDLPFC on frontal theta ‐ an oscillatory marker of cognitive control ‐ in response to speech and limb inhibition, during a Go/No‐Go task in 21 neurotypical adults. Electroencephalography data demonstrated that both speech and limb No‐Go elicited prominent theta activity over right prefrontal electrodes, with stronger activity for speech compared to limb. Moreover, we found that cathodal stimulation significantly increased theta power over right prefrontal electrodes for speech versus limb No‐Go. Source analysis revealed that cathodal, but not sham, stimulation increased theta activity within rDLPFC and bilateral premotor cortex for speech No‐Go compared to limb movement inhibition. These findings complement our previous report and suggest (1) right prefrontal theta activity is an amodal oscillatory mechanism supporting speech and limb inhibition, (2) larger theta activity in prefrontal electrodes for speech versus limb following cathodal stimulation may reflect allocation of additional neural resources for a more complex motor task, such as speech compared to limb movement. These findings have translational implications for conditions such as Parkinson's disease, wherein both speech and limb movement are impaired.
