The purpose of this study was to evaluate the effectiveness of Fluori-Methane vapocoolant spray, as used in the spray and stretch technique, on decreasing a prolonged silent period duration in the masseter muscle. Ten subjects were selected, all of whom were identified as having masseter muscle dysfunction and/or spasm. The population consisted of two males and eight females, whose ages ranged from 24-58. The silent period duration of the masseter was measured following elicitation of the jaw-jerk reflex. Five readings were taken and the mean silent period duration was calculated. All means longer than 35 milliseconds were considered prolonged. An EDX 1000 electromyograph and Beckman standard size silver surface electrodes were used in recording the data. The amount of mandibular depression available was also measured. Once these measurements were completed, each subject was treated using Fluori-Methane vapocoolant spray, as used in the spray and stretch technique. The silent period duration and ...
Temporomandibular disorders are a group of orofacial pain conditions that are commonly identified in the general population. Like many other chronic pain conditions, they can be associated with anxiety/depression, which can be related to changes in the activity of the dorsolateral prefrontal cortex. Some studies have demonstrated clinical improvement in subjects with chronic pain who are given therapeutic neuromodulation. Transcranial direct current stimulation is a noninvasive brain stimulation technique that allows the modulation of neuronal membranes. This therapy can enhance or inhibit action potential generation in cortical neurons. In some instances, medications acting in the central nervous system may be helpful despite their adverse side effects. It is important to determine if cathodal transcranial direct current stimulation over the dorsolateral prefrontal cortex, an area that modulates emotion and motor cortex excitability, has an analgesic effect on chronic temporomandibular disorders pain.
TY - JOUR. T1 - Can Transcranial Electrical Stimulation Localize Brain Function?. AU - Karabanov, Anke Ninija. AU - Bicalho Saturnino, Guilherme. AU - Thielscher, Axel. AU - Siebner, Hartwig Roman. PY - 2019. Y1 - 2019. N2 - Transcranial electrical stimulation (TES) uses constant (TDCS) or alternating currents (TACS) to modulate brain activity. Most TES studies apply low-intensity currents through scalp electrodes (,= 2 mA) using bipolar electrode arrangements, producing weak electrical fields in the brain (, 1 V/m). Low-intensity TES has been employed in humans to induce changes in task performance during or after stimulation. In analogy to focal transcranial magnetic stimulation, TES-induced behavioral effects have often been taken as evidence for a causal involvement of the brain region underlying one of the two stimulation electrodes, often referred to as the active electrode. Here, we critically review the utility of bipolar low-intensity TES to localize human brain function. We summarize ...
Objectives Recent cellular work in TDP-43 models of ALS convincingly demonstrated the importance of somatostatin interneuronal circuits in mediating corticomotoneuronal hyperexcitability, previously indirectly measured by short interval intracortical inhibition (SICI). Somatostatin interneurons reside in layers 2-3 of the primary motor cortex, with their output projecting directly onto and modulating pyramidal tract neurons. These circuits can be non-invasively interrogated using TMS. As such, the present study developed a novel threshold tracking TMS technique of this excitatory output, termed short interval intracortical facilitation (or SICF), and postulated that it would be increased in ALS patients when compared with healthy controls. ...
Consideration was given to means of increasing the reliability and muscle specificity of paired associative stimulation (PAS) by utilising the phenomenon of crossed-facilitation. Eight participants completed three separate sessions: isometric flexor contractions of the left wrist at 20% of maximum voluntary contraction (MVC) simultaneously with PAS (20 s intervals; 14 min duration) delivered at the right median nerve and left primary motor cortex (M1); isometric contractions at 20% of MVC; and PAS only (14 min). Eight further participants completed two sessions of longer duration PAS (28 min): either alone or in conjunction with flexion contractions of the left wrist. Thirty motor potentials (MEPs) were evoked in the right flexor (rFCR) and extensor (rECR) carpi radialis muscles by magnetic stimulation of left M1 prior to the interventions, immediately post-intervention, and 10 min post-intervention. Both 14 and 28 min of combined PAS and (left wrist flexion) contractions resulted in reliable ...

Objective: Presurgical functional brain mapping is essential for optimized resection planning of eloquently located brain tumors. Functional magnetic resonance imaging (fMRI) has been the most established method for presurgical motor mapping but was shown to have a rather low test-retest reliability, especially for the face and the tongue area. Recently, neuronavigated Transcranial Magnetic Stimulation (nTMS) has attracted rising attention as an alternative motor mapping method applicable for clinical routine. Anyway, little was known about the reliability of nTMS. Thus, we compared the reliability of both motor mapping approaches in a preclinical trial.. Methods: We examined 10 healthy, right-handed subjects on three days (d0, d3-5, week 3-5) by nTMS (eXimia 3.2.2, 110% of resting motor threshold on dominant primary motor cortex, MEP recordings: abductor pollicis brevis muscle, plantaris muscle, perioral muscles, tongue) and fMRI (Siemens 3T Trio, motor paradigms: [1] bilateral thumb abduction, ...
Mental or cognitive brain functions, and the effect on them of abnormal psychiatric diseases, are difficult to approach through molecular biological techniques due to the lack of appropriate assay systems with objective measures. We therefore study laws of behavioral organization, specifically how resting and active periods are interwoven throughout daily life, using objective criteria, and first discover that identical laws hold both for healthy humans subject to the full complexity of daily life, and wild-type mice subject to maximum environmental constraints. We find that active period durations with physical activity counts successively above a predefined threshold, when rescaled with individual means, follow a universal stretched exponential (gamma-type) cumulative distribution, while resting period durations below the threshold obey a universal power-law cumulative distribution with identical parameter values for both of the mammalian species. Further, by analyzing the behavioral organization of

Specific Primary Aims include:. Aim # 1. The investigators explore the feasibility of using the TMS to investigate the cortical excitability and to inhibit meth cue craving in meth dependent population. The investigators anticipate that meth elevates cortical excitability measured by motor threshold, causes changes of cortical silent period, and RC. The investigators also anticipate that paired pulse measures (short-interval intracortical inhibition, short-interval intracortical facilitation and long-interval intracortical inhibition) will be different from healthy control, which are more directly linked to glutamatergic cortical facilitation and GABAergic inhibition, respectively.. Aim # 2. Given the change of the cortical excitability in meth users, the investigators will use inhibiting TMS (1 Hz) over medial prefrontal cortex to study whether TMS can be used to reduce cue craving. The investigators hypothesize that repetitive TMS reduce meth cue craving in meth dependent population compared ...
Previous researchers have approved the ability of anodal transcranial direct current stimulation (a-tDCS) of the primary motor cortex (M1) to enhance corticospinal excitability (CSE). The primary aim of the current study was to investigate the effect of concurrent stimulation of M1 and a functionally connected cortical site of M1 on CSE modulation. This new technique is called unihemispheric concurrent dual-site a-tDCS (a-tDCSUHCDS). The secondary aim was to investigate the mechanisms underlying the efficacy of this new approach in healthy individuals. In a randomized crossover study, 12 healthy right-handed volunteers received a-tDCS under five conditions: a-tDCS of M1, a-tDCSUHCDS of M1- dorsolateral prefrontal cortex (DLPFC), a-tDCSUHCDS of M1- primary sensory cortex (S1), a-tDCSUHCDS of M1- primary visual cortex (V1), and sham a-tDCSUHCDS. Peak-to-peak amplitude of transcranial magnetic stimulation (TMS) induced MEPs, short-interval intracortical inhibition and intracortical facilitation were
The early motor manifestations of sporadic amyotrophic lateral sclerosis (ALS), while rarely documented, reflect failure of adaptive complex motor skills. The development of these skills correlates with progressive evolution of a direct corticomotoneuronal system that is unique to primates and markedly enhanced in humans. The failure of this system in ALS may translate into the split hand presentation, gait disturbance, split leg syndrome and bulbar symptomatology related to vocalisation and breathing, and possibly diffuse fasciculation, characteristic of ALS. Clinical neurophysiology of the brain employing transcranial magnetic stimulation has convincingly demonstrated a presymptomatic reduction or absence of short interval intracortical inhibition, accompanied by increased intracortical facilitation, indicating cortical hyperexcitability. The hallmark of the TDP-43 pathological signature of sporadic ALS is restricted to cortical areas as well as to subcortical nuclei that are under the direct ...
Semantic Scholar extracted view of Prolonged cortical silent period after transcranial magnetic stimulation in generalized epilepsy. by Roberto M Cantello
This article reviews the physiology and application of the currently available paired-pulse protocols. Paired-pulse transcranial magnetic stimulation (TMS) techniques study the modulation of human motor cortical excitability. Paired-pulse experiments are designed to give insight into the nature of the cortical circuitry activated by TMS. Changes in motor cortical excitability produced by the conditioning pulse are estimated by changes in the size of the conditioned motor-evoked potential (MEP). It is possible to identify specific abnormalities in the balance between inhibitory and facilitatory processes, even if the pathology lies in abnormal afferent signalling to the motor cortex rather than in the motor cortex itself. The conclusion that emerges from the studies on interhemispheric interactions is that it is now possible by means of TMS protocols to chart long-range functional interhemispheric connectivity of remote areas of the human brain. ...

The effects of transcranial electrical stimulation (tES) have been documented for a variety of mental functions, including numerical cognition. This article first reviews 2 prominent forms of tES, transcranial direct current stimulation (tDCS) and transcranial random noise stimulation (tRNS). This is followed by an assessment of the applications of this technology in the enhancement of aspects of numerical cognition, including numerosity, magnitude representation, and more complex arithmetic operations. The review concludes with discussions of directions for future research. These include the need to take individual differences into account in experimental designs, extending research to individuals with difficulties and deficits in working with numbers, the need to consider potential cognitive costs that may offset cognitive benefits of tES. A recurring theme in this article is the need to move toward greater ecological validity of experimental findings.
OBJECTIVE: This study tested the hypothesis that degeneration of the corticofugal tracts (CFTs) is related to poor functional outcome in the upper limb after stroke. METHODS: . The authors used diffusion tensor imaging to determine the degree of white matter integrity of the CFT (FA(AH/UH)) in chronic stroke patients and controls. The functional integrity of the corticospinal pathway was examined using transcranial magnetic stimulation. Recruitment curves and silent period duration were measured. The relationship between FA(AH/UH) and functional outcome of the upper limb was also assessed using a battery of upper limb function tests. RESULTS: In patients, FA( AH/UH) correlated positively with the slope of recruitment curves (RC(AH/UH)) and grip strength. FA(AH/UH) also correlated negatively with the silent period duration (SP(AH/UH)). According to the FA(AH/UH), patients were also classified into groups with minimal or extensive Wallerian degeneration (WD). Patients with more extensive WD had poorer

Background Gamma (γ) oscillations (30-50 Hz) have been shown to be excessive in patients with schizophrenia (SCZ) during working memory (WM). WM is a cognitive process that involves the online maintenance and manipulation of information that is mediated largely by the dorsolateral prefrontal cortex (DLPFC). Repetitive transcranial magnetic stimulation (rTMS) represents a non-invasive method to stimulate the cortex that has been shown to enhance cognition and γ oscillatory activity during WM. Methodology and Principal Findings We examined the effect of 20 Hz rTMS over the DLPFC on γ oscillatory activity elicited during the N-back task in 24 patients with SCZ compared to 22 healthy subjects. Prior to rTMS, patients with SCZ elicited excessive γ oscillatory activity compared to healthy subjects across WM load. Active rTMS resulted in the reduction of frontal γ oscillatory activity in patients with SCZ, while potentiating activity in healthy subjects in the 3-back, the most difficult condition.
Introduction: Intensive task practice assisted by robots is a promising treatment for hemiparesis after stroke. However, not all respond to the treatment, so a better patient selection method is needed. Previous studies have shown that motor cortical responsiveness to transcranial magnetic stimulation (TMS) may predict gains from practice and may change with those gains.. Hypotheses: In the first study, we hypothesized that more intact motor cortical pathways would predict better response to treatment, and that motor cortical excitability would increase when motor function improved. In the second study we had the same hypotheses, and: Motor cortical excitability would increase during a single session of intensive therapy, and that this increase would itself predict gains in motor function.. Methods: Study 1: participants in trials of upper extremity robotic rehabilitation in chronic stroke were recruited to have TMS measures for extensor digitorum communis (EDC) and biceps muscles before and ...
Repetitive transcranial magnetic stimulation (rTMS) is primarily used in humans to change the state of corticospinal excitability. To assess the efficacy of different rTMS stimulation protocols, motor evoked potentials (MEPs) are used as a readout due to their non-invasive nature. Stimulation of the motor cortex produces a response in a targeted muscle, and the amplitude of this twitch provides an indirect measure of the current state of the cortex. When applied to the motor cortex, rTMS can alter MEP amplitude, however results are variable between participants and across studies. In addition, the mechanisms underlying any change and its locus are poorly understood. In order to better understand these effects, MEPs have been investigated in vivo in animal models, primarily in rats. One major difference in protocols between rats and humans is the use of general anesthesia in animal experiments. Anesthetics are known to affect plasticity-like mechanisms and so may contaminate the effects of an rTMS
Non-invasive brain stimulation (NIBS) are techniques widely employed in the last decades to the study of physiology of cognitive processes, and bring the promise of being a complementary therapeutic intervention to neuropsychiatric disorders. In this doctoral dissertation, I attempted to advance in methodologically rigorous protocols to influence normal brain physiology and search for solutions to modulate memory activity, targeting different anatomical nodes of the verbal episodic memory network with transcranial electrical stimulation (tDCS, TACS). In the first study, I aimed to modulate memory performance by applying a focal multi-electrode tDCS targeting primarily the dorso-lateral pre-frontal cortex (DLPFC). In the second study, the target was moved to the left temporal cortex, aiming to interfere and manipulate with the temporal characteristics of the encoding process by the application of tACS. ...

Current functional MRI (fMRI) approaches assess underlying neuronal activity through monitoring the related local variations in cerebral blood oxygenation, blood volume and blood flow. This vascular response is likely to vary across brain regions and across individuals, depending on the composition of the local vascular bed and on the vascular capacity to dilate. The most widely used technique uses the blood oxygen level dependent (BOLD) fMRI signal, which arises from a complex combination of all of these factors. The model of handedness provides a case where one brain region (dominant motor cortex) is known to have a stronger BOLD response over another (non-dominant motor cortex) during hand motor task performance. We predict that this is accompanied by a higher vascular reactivity in the dominant motor cortex, when compared with the non-dominant motor cortex. Precise measurement of end-tidal CO2 and a novel sinusoidal CO2 respiratory challenge were combined with the high sensitivity and finer spatial

N2 - Purpose: To demonstrate the feasibility of turning transcranial magnetic stimulation (TMS) coil for MRI signal reception. Methods: A critically coupled network was formed by using a resonated turn of TMS coil as the secondary and a regular radiofrequency (RF) coil as the primary. A third coil was positioned between the two coils for detuning during RF transmission. Bench measurement, numerical simulation, and MRI experiment were performed for validation. Results: The signal-to-noise ratio of the proposed 2-in-1 coil is 35% higher in its field of view, compared with a MRI-only reference coil of the same size, made by the same material, and backed up by an untuned TMS coil, but lower than a RF surface coil of the same size without any TMS coil nearby. Spin-echo images of the human brain further validated its ...
Some researchers are cautious in interpreting the research data [14] as they question the neuronal functional and outcome measure of MEP or RMT. They argue that MEP (and thereby the related RMT) used in most of the research is poorly defined and by itself is a poor and indirect measure of brain changes. They propose the measurement of cortical silent period (CSP) which is the period of suppression of EMG activity from MEP to the return of voluntary muscle activity after application of a suprathreshold stimulus. CSP purportedly is a direct and an easy measure of cortical change Poor quality reporting of research data requires making assumptions while interpretation of the findings [14] and thereby reduces the overall applicability and quality Clinical applicability requires shortening of duration of each session and along with shortening of the overall duration of a course of rTMS treatment. First of these challenges is being addressed through the use of theta (θ) burst stimulation, which ...

In the patient group the Jebsen Taylor Test will be used to assess gross motor function. To better understand the mechanisms underlying the proposed behavioral gains, we will use single- and paired pulse transcranial magnetic stimulation (TMS) to identify corticomotor excitability changes.

Background and objective: Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive nerve stimulation technique that has the potential to improve cognitive function. However, there have been few randomized controlled trials (RCTs) that evaluated the effectiveness of rTMS on cognitive function and the relapse in patients with bipolar disorder. Participants and methods: This double-blind parallel RCT will be conducted at The Affiliated Brain Hospital of Guangzhou Medical University (Guangzhou Huiai Hospital), China. A total of 74 bipolar disorder patients will be recruited and randomly assigned to a trial group (n = 37) and control group (n = 37). Repetitive transcranial magnetic stimulation and sham repetitive transcranial magnetic stimulation will be applied over the left dorsolateral prefrontal cortex in the trial group and control group, respectively. This trial was designed on March 2, 2017 and was approved by the Ethics Committee of The Affiliated Brain Hospital of Guangzhou ...

Reputation formation pervades human social life. In fact, many people go to great lengths to acquire a good reputation, even though building a good reputation is costly in many cases. Little is known about the neural underpinnings of this important social mechanism, however. In the present study, we show that disruption of the right, but not the left, lateral prefrontal cortex (PFC) with low-frequency repetitive transcranial magnetic stimulation (rTMS) diminishes subjects ability to build a favorable reputation. This effect occurs even though subjects ability to behave altruistically in the absence of reputation incentives remains intact, and even though they are still able to recognize both the fairness standards necessary for acquiring and the future benefits of a good reputation. Thus, subjects with a disrupted right lateral PFC no longer seem to be able to resist the temptation to defect, even though they know that this has detrimental effects on their future reputation. This suggests an ...

To improve our understanding of the combined transcranial magnetic stimulation (TMS) and electroencephalography (EEG) method in general, it is important to study how the dynamics of the TMS-modulated brain activity differs from the dynamics of spontaneous activity. In this paper, we introduce two quantitative measures based on EEG data, called mean state shift (MSS) and state variance (SV), for evaluating the TMS-evoked changes in the brain-state dynamics. MSS quantifies the immediate TMS-elicited change in the brain state, whereas SV shows whether the rate at which the brain state changes is modulated by TMS. We report a statistically significant increase for a period of 100-200 ms after the TMS pulse in both MSS and SV at the group level. This indicates that the TMS-modulated brain state differs from the spontaneous one. Moreover, the TMS-modulated activity is more vigorous than the natural activity ...
The central and unique findings of this study are that both anodal and cathodal tDCS enhance planning ability as quantified by TOL task performance and that, although not initially hypothesized, these effects are learning phase dependent. Unlike the negative findings from studies using transcranial magnetic stimulation over left DLPFC on TOL performance (Loo et al., 1999; Roth et al., 2004), in our study only 15 min of 1 mA of real tDCS led to altered RT and ACC. The polarity-specific effects were more pronounced at the higher task load level, and sustained for up to a year without further tDCS application. To our knowledge this is the first study comparing long- and short-term effects of tDCS of the DLPFC on TOL planning ability and cognitive skill learning. We cannot overlook, however, that gender differences have been found in TOL BOLD activation patterns in which females showed greater recruitment of the DLPFC than males (Boghi et al., 2006), and since our study had a larger proportion of ...
