The perturbational complexity index (PCI) measures the spatiotemporal dynamics of transcranial magnetic stimulation (TMS)-evoked electroencephalography (EEG) potentials (TEPs) [1]. High PCI values reflect joint presence integration and differentiation in thalamocortical networks conscious brains Low have been reported during natural non-rapid eye movement sleep, disorders consciousness, unrespo...

Repetitive transcranial magnetic stimulation (rTMS) of the human motor cortex can produce long-lasting changes in the excitability of the motor cortex to single pulse transcranial magnetic stimulation (TMS). rTMS may increase or decrease motor cortical excitability depending critically on the characteristics of the stimulation protocol. However, it is still poorly defined which mechanisms and c...

Abstract Introduction: In many neurodevelopmental disorders impaired synaptic plasticity is believed to be a key pathophysiological mechanism. It can studied through transcranial magnetic stimulation (TMS). TMS over the primary motor cortex (M1) triggers oscillations called I-waves that show three maxima (I1-I3). seem important in mechanisms. Hence targeting directly might increase effects of i...

Noninvasive brain stimulation has developed as a promising tool for cognitive neuroscientists. Transcranial magnetic (TMS) and direct current (tDCS) stimulation allow researchers to purposefully enhance or decrease excitability in focal areas of the brain. The purpose of this article is to review information on the use of TMS and tDCS as research tools to facilitate motor memory formation, moto...

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...

Introduction: Transcranial magnetic stimulation (TMS) is a useful tool for assessment of corticospinal excitability (CSE) changes in both healthy individuals and patients with brain disorders. The usefulness of TMS-elicited motor evoked potentials (MEPs) for the assessment of CSE in a clinical context depends on their intra-and inter-session reliability. This study aimed to evaluate if removal ...

Transcranial magnetic stimulation (TMS) is a new technique that has been used for the treatment of neuropsychiatric disorders, specially depression. It uses a magnetic stimulator that generates a magnetic field that is applied over the patient's skull with a coil. Possible seizures may be induced accidentally by TMS. TMS is usually used with sub threshold stimuli and seizures may occur by chanc...
