Time-frequency analysis of short-lasting modulation of EEG induced by TMS during wake, sleep deprivation and sleep
The occurrence of dynamic changes in spontaneous electroencephalogram (EEG) rhythms in the awake state or sleep is highly variable. These rhythms can be externally modulated during transcranial magnetic stimulation (TMS) with a perturbation method to trigger oscillatory brain activity. EEG-TMS co-registration was performed during standard wake, during wake after sleep deprivation and in sleep i...
متن کاملRAMs and TMs
A word-RAM consists of: • A fixed set of instructions P1, . . . , Pq. Allowed instructions are: – Modular arithmetic and integer division on registers; the standard model for a RAM machine does not have negative numbers, but you can verify that allowing signed integers doesn’t chance the power of the model. – Bitwise operations on registers. – Loading a constant into a register. – Transfering v...
متن کاملTMS-Induced Cortical Potentiation during Wakefulness Locally Increases Slow Wave Activity during Sleep
BACKGROUND Sleep slow wave activity (SWA) is thought to reflect sleep need, increasing in proportion to the length of prior wakefulness and decreasing during sleep. However, the process responsible for SWA regulation is not known. We showed recently that SWA increases locally after a learning task involving a circumscribed brain region, suggesting that SWA may reflect plastic changes triggered ...
متن کاملRight-frontal slow negative potentials evoked by occipital TMS are reduced in NREM sleep.
Occipital transcranial magnetic stimulation applied in a task-free experimental setup leads to enhanced relative negativity of frontally recorded evoked slow potentials under the influence of caffeine (Murd et al., 2010 [26]). We tested whether this increased negativity could be reversed when a similar magnetic stimulation is applied during quiet sleep where consciousness is absent. Consistentl...
متن کاملTMS-EEG co-registration: on TMS-induced artifact.
OBJECTIVE The combination of brain stimulation by transcranial magnetic stimulation (TMS) and simultaneous electroencephalographic (EEG) recording has the potential to be of great value for understanding human brain functions. Recording EEG during TMS can be technically challenging because TMS induces a very strong electrical field that can saturate recording amplifiers for a long duration. Adv...
