Can you do TMS and fMRI at the same time?
TMS and fMRI can also be separated in time (offline approach). A conditioning session of repetitive TMS (rTMS) may be used to induce rapid reorganization in functional brain networks. The temporospatial patterns of TMS-induced reorganization can be subsequently mapped using fMRI.
Can you do neurofeedback and TMS at the same time?
Thus, the efficacy of TMS could be amplified in depression by taking into account the cerebral activity during the stimulation sessions, in particular on the electroencephalographic plane. However, TMS may also help patients increase their EEG response during Neurofeedback sessions.
What is the difference between fMRI and TMS?
fMRI identifies areas of hemodynamic changes during task performance while TMS provides electrophysiologic data concerning the localization and density of cortical motoneurons.
Why is TMS better than fMRI?
Transcranial Magnetic Stimulation (TMS) allows to noninvasively probe neural excitability, while concurrent fMRI can log the induced activity propagation through connected network nodes. However, this approach ignores ongoing oscillatory fluctuations which strongly affect network excitability and concomitant behavior.
Is neurofeedback better than TMS?
The benefits of neurofeedback Neurofeedback has several advantages over TMS: While TMS usually requires five 20–40-minute sessions per week for six to seven weeks, neurofeedback is usually done 1-3 times per week. The course of treatment depends on the individual. TMS generally targets depression only.
Is TMS structural or functional?
Unlike ordinary MRI, which is used to visualize the brain’s structures, functional magnetic resonance imaging (fMRI) is used to visualize the activity in its various regions….

What part of the brain is affected by TMS?
This electromagnetic coil creates a magnetic field that is specifically targeted over the left dorsolateral prefrontal cortex (DLPFC) which is the area of the brain responsible for mood regulation.
How is TMS different from MRI?
MRIs are used for diagnostic purposes, like x-rays. TMS, on the other hand, is a treatment for depression. While MRIs creates images of the whole body, the brain or other areas that are wider, TMS focused on a small, targeted area of the brain.
Can TMS and EEG be used to probe the brain?
The combination of transcranial magnetic stimulation (TMS) with simultaneous electroencephalography (EEG) provides us the possibility to non-invasively probe the brain’s excitability, time-resolved connectivity and instantaneous state.
How does TMS work in the brain?
The electric currents induced in the brain by TMS can depolarize cell membranes so that voltage-sensitive ion channels are opened and action potentials are initiated.
How long should the EEG amplifier be switched off after TMS?
The EEG amplifiers were switched off 10 ms before the TMS pulse and switched back on 1 ms after; the TMS artifact remained for approximately 10 ms post-stimulus. An effective way to deal with the electromagnetic artifact was developed by Virtanen et al. (1999).
Are TMS-evoked EEG averaged responses reproducible?
In contrast to the high variability of motor evoked potentials (MEPs), the TMS-evoked EEG averaged responses are generally highly reproducible, provided that the delivery and targeting of TMS is well controlled and stable from pulse to pulse and between experiments.
