In the motor cortex (M1), transcranial direct current stimulation (tDCS) can effectively prime excitability changes that are evoked by a subsequent train of repetitive transcranial magnetic stimulation (rTMS). The authors examined whether tDCS can also prime the cortical response to rTMS in the human visual cortex. METHODS. In nine healthy subjects, the authors applied tDCS ( 10 minutes; +/- 1 mA) to the occipital cortex. After tDCS, they applied a 20-second train of 5 Hz rTMS at 90% of phosphene threshold ( PT) intensity. A similar rTMS protocol had previously demonstrated a strong priming effect of tDCS on rTMSinduced excitability changes in M1. PTs were determined with single-pulse TMS before and immediately after tDCS and twice after rTMS. RESULTS. Anodal tDCS led to a transient decrease in PT, and subsequent 5 Hz rTMS induced an earlier return of the PT back to baseline. Cathodal tDCS produced a short-lasting increase in PT, but 5 Hz rTMS did not influence the tDCS-induced increase in PT. In a control experiment on four subjects, a 20-second train of occipital 5 Hz rTMS left the PT unchanged, whereas a 60-second train produced a similar decrease in PT as anodal tDCS alone. CONCLUSIONS. Compared with previous work on the M1, tDCS and rTMS of the visual cortex only produce short-lasting changes in cortical excitability. Moreover, the priming effects of tDCS on subsequent rTMS conditioning are relatively modest. These discrepancies point to substantial differences in the modifiability of human motor and visual cortex."],["dc.identifier.doi","10.1167/iovs.07-0706"],["dc.identifier.isi","000251450800055"],["dc.identifier.pmid","18055832"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/48190"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Assoc Research Vision Ophthalmology Inc"],["dc.relation.issn","0146-0404"],["dc.title","Bidirectional modulation of primary visual cortex excitability: A combined tDCS and rTMS study"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]Details DOI PMID PMC WOS2011Journal Article [["dc.bibliographiccitation.firstpage","2802"],["dc.bibliographiccitation.issue","6"],["dc.bibliographiccitation.journal","Journal of Neurophysiology"],["dc.bibliographiccitation.lastpage","2810"],["dc.bibliographiccitation.volume","105"],["dc.contributor.author","Lang, Nicolas"],["dc.contributor.author","Nitsche, Michael A."],["dc.contributor.author","Dileone, Michele"],["dc.contributor.author","Mazzone, Paolo"],["dc.contributor.author","De Andres-Ares, Javier"],["dc.contributor.author","Diaz-Jara, Luis"],["dc.contributor.author","Paulus, Walter J."],["dc.contributor.author","Di Lazzaro, Vincenzo"],["dc.contributor.author","Oliviero, Antonio"],["dc.date.accessioned","2018-11-07T08:55:20Z"],["dc.date.available","2018-11-07T08:55:20Z"],["dc.date.issued","2011"],["dc.description.abstract","Lang N, Nitsche MA, Dileone M, Mazzone P, De Andres-Ares J, Diaz-Jara L, Paulus W, Di Lazzaro V, Oliviero A.

Here we examined the influence of two different pulse durations on several physiological parameters of primary motor cortex excitability obtained using single pulse TMS. Methods: A Magstim Bistim(2) stimulator was used to produce TMS pulses of two distinct durations. For either pulse duration we measured, in healthy volunteers, resting and active motor thresholds, recruitment curves of motor evoked potentials in relaxed and contracting hand muscles as well as contralateral (cSP) and ipsilateral (iSP) cortical silent periods. Results: Motor thresholds decreased by 20% using a 1.4 times longer TMS pulse compared to the standard pulse, while there was no significant effect on threshold adjusted measurements of cortical excitability. The longer pulse duration reduced pulse-to-pulse variability in cSP. Conclusions: The strength of a TMS pulse can be adjusted both by amplitude or pulse duration. TMS pulse duration does not affect threshold-adjusted single pulse measures of motor cortex excitability. Significance: Using longer TMS pulses might be an alternative in subjects with very high motor threshold. Pulse duration might not be relevant as long as TMS intensity is threshold-adapted. This is important when comparing studies performed with different stimulator types. (C) 2010 International Federation of Clinical Neurophysiology. Published by Elsevier Ireland Ltd.

Since unrestricted neuroplastic modifications of network connectivity will result in a cle-stabilization of the system, metaplastic modification rules have been proposed for keeping plastic connectivity changes within a useful dynamic range. In this connection, the modification threshold to achieve synaptic strengthening is thought to correlate negatively with the history of activity of the respective neurons, i.e. high previous activity enhances the threshold for synaptic strengthening and vice versa. However, the relevance of metaplasticity for actual learning processes has not been tested so far. We reduced or enhanced motor cortex excitability before performance of the serial reaction time task (SRTT), a sequential motor learning paradigm, and a reaction time task (RTT) by transcranial direct current stimulation (tDCS). If homeostatic rules apply, excitability-diminishing cathodal tDCS should improve subsequent motor learning, especially if combined with the partial NMDA receptor-agoniSt D-cycloserine, which selectively enhances efficacy of active receptors, while excitability-enhancing anodal tDCS should reduce it. Only the results for anodal tDCS, when combined with D-cycloserine, were in accordance with the rules of homeostatic plasticity. We conclude that homeostatic plasticity, as tested here, has a limited influence on implicit sequential motor learning. (C) 2008 Elsevier Ltd.

We applied rTMS over the primary motor cortex contralateral to the dominant hand, using 80 stimuli at 5 Hz frequency at an intensity yielding baseline motor evoked potential (MEP) amplitudes of 1 mV. Monophasic stimulation was always more efficient than biphasic. Facilitation was induced by intracerebral anteriorly directed current flow and inhibition by posteriorly oriented current flow, although only initially for approximately 30 pulses. The early inhibition was absent when studied during a tonic muscle contraction. Several mechanisms could account for these findings. They include a more efficient excitation of inhibiting circuits by posteriorly oriented pulses, and a back-propagating D-wave inhibiting early I-waves and thus inducing early inhibition of MEP amplitude.

We used six blocks of 200 pulses at 5-Hz frequency and 90% active motor threshold intensity and controlled for corticospinal excitability changes using motor-evoked potential (MEP) amplitudes and latencies elicited by suprathreshold pulses before, in between, and after rTMS.

The neurophysiological mechanisms underlying nicotine-induced behavioral changes have been sparsely studied, especially in humans. Global cholinergic activation focuses on plasticity in humans. However, the specific contribution of nicotinic receptors to these effects is unclear. Henceforth, we explored the impact of nicotine on non-focal neuroplasticity induced by transcranial direct current stimulation (tDCS) and focal, synapse-specific plasticity induced by paired associative stimulation (PAS) in healthy non-smoking individuals. Forty-eight subjects participated in the study. Each subject received placebo and nicotine patches combined with one of the stimulation protocols to the primary motor cortex in different sessions. Transcranial magnetic stimulation (TMS)-elicited motor-evoked potential (MEP) amplitudes were recorded as a measure of corticospinal excitability until the evening of the second day following the stimulation. Nicotine abolished or reduced both PAS-and tDCS-induced inhibitory neuroplasticity. Non-focal facilitatory plasticity was also abolished, whereas focal facilitatory plasticity was slightly prolonged by nicotine. Thus, nicotinergic influence on facilitatory, but not inhibitory plasticity mimics that of global cholinergic enhancement. Therefore, activating nicotinic receptors has clearly discernable effects from global cholinergic activation. These nicotine-generated plasticity alterations might be important for the effects of the drug on cognitive function.
