Theta burst stimulation on human motor cortex

Theta burst stimulation over the primary motor cortex does not induce cortical plasticity in Parkinson’s disease

“…When applied in healthy subjects continuous TBS (cTBS) depresses cortical excitability, whereas intermittent TBS (iTBS) enhances cortical excitability. ITBS has no effect on intracortical facilitation (ICF), whereas a small decrease in ICF was described after cTBS [5]. CTBS reduces the MEP amplitude evoked from contralateral hand muscles [5,6].…”

“…Theta burst stimulation (TBS) is a new rTMS protocol characterized by high frequency and low intensity stimulation [5]. When applied in healthy subjects continuous TBS (cTBS) depresses cortical excitability, whereas intermittent TBS (iTBS) enhances cortical excitability.…”

“…Huang et al 2005) when they derive hypothetical durations of likely eVects on the monkey brain. Although we welcome inter-relation of human and non-human-primate studies, we note that important methodological diVerences such as the diVerent size of TMS coils used in Gerits et al (2011) (much smaller than the TMS coils normally used in human studies) and potentially the diVerent layout of speciWc brain areas relative to the scalp will need to be considered carefully when comparing or extrapolating across species.…”

“…Boroojerdi, Prager, Muellbacher, & Cohen, 2000), and the rule of thumb is that the effect will last about half the duration period of the stimulation (Robertson, Theoret, & Pascual-Leone, 2003). Another example, is the recently developed TMS repetitive stimulation protocol, theta-burst stimulation (TBS), which involves the continuous delivery of triplets of pulses at 50 Hz with 200 ms between the pulse triplets (Huang, Edwards, Rounis, Bhatia, & Rothwell, 2005). One advantage of this protocol is that with very short applications times (e.g.…”
