TMS-evoked cortical responses can be measured using simultaneous electroencephalography (TMS-EEG) to directly quantify cortical connectivity in the human brain. The purpose of this study was to evaluate interhemispheric cortical connectivity between the primary motor cortices (M1s) in participants with chronic stroke and controls using TMS-EEG. Ten participants with chronic stroke and four cont...

BACKGROUND TMS is being increasingly used as a noninvasive brain stimulation technique for the therapeutic management of partial epilepsies. However, the acute effects of TMS on epileptiform discharges (EDs, i.e. interictal epileptiform activity and subclinical electrographic seizure patterns) remain unexplored. OBJECTIVE To investigate whether TMS can modulate EDs in partial epilepsy. METH...

The effects of transcranial magnetic stimulation (TMS) vary depending on the brain state at the stimulation moment. Four mechanisms have been proposed to underlie these effects: (1) virtual lesion--TMS suppresses neural signals; (2) preferential activation of less active neurons--TMS drives up activity in the stimulated area, but active neurons are saturating; (3) noise generation--TMS adds ran...

OBJECTIVE This study compared the usefulness of transcranial magnetic stimulation (TMS), diffusion tensor tractography (DTT), and the combined study of TMS and DTT for prediction of motor outcome in patients with corona radiata infarct. METHODS Fifty-eight patients with complete motor weakness of the affected hand were recruited. TMS and DTT were performed in the early stage (7-28 days) of st...

Transcranial magnetic stimulation (TMS) is a neuropsychiatric tool that can serve as a useful method to better understand the neurobiology of cognitive function, behavior, and emotional processing. The purpose of this article is to examine the utility of TMS as a means to measure neocortical function in neuropsychiatric disorders in general, and schizophrenia in particular, for the Cognitive Ne...

SWISS-PROT release 42 [1] contains a total of 2,028 transmembrane (TM) protein sequences with seven TM helices (7-tms), out of which 1,762 sequences are G-protein-coupled receptors (GPCRs). This means that a TM protein predicted correctly as 7-tms should be a GPCR with a reliability of 87% even without using any other information. Then, the questions are how much degree TM topology prediction m...

The present study investigated whether transcranial magnetic stimulation (TMS) to the parietal cortex improves the performance of healthy persons in a spatial working memory (WM) task. The effect of TMS on the frontal cortex was examined by measuring oxygenated hemoglobin (oxy-Hb) with near-infrared spectroscopy. Fifty-two healthy persons received either 100% resting motor threshold TMS at 5 Hz...

Abstract While TMS represents an exciting treatment tool for psychiatry, clinical response depression is <50%. Furthermore, <1% of available protocols (frequency, amplitude, pattern, etc) are utilized clinically. The low rate and under-utilization novel patterns partially because we lack a mechanistic understanding the circuit-level neuromodulatory changes induced by TMS. This impedes optimizat...

OBJECT Within the primary motor cortex, navigated transcranial magnetic stimulation (nTMS) has been shown to yield maps strongly correlated with those generated by direct cortical stimulation (DCS). However, the stimulation parameters for repetitive nTMS (rTMS)-based language mapping are still being refined. For this purpose, the present study compares two rTMS protocols, which differ in the ti...
