Theoretical principles of deep brain stimulation induced synaptic suppression.

Deep brain stimulation (DBS) is a successful clinical therapy for a wide range of neurological disorders; however, the physiological mechanisms of DBS remain unresolved. While many different hypotheses currently exist, our analyses suggest that high frequency (∼100 Hz) stimulation-induced synaptic suppression represents the most basic concept that can be directly reconciled with experimental recordings of spiking activity in neurons that are being driven by DBS inputs.

Noninvasive brain stimulation combined with other therapies improves gait speed after stroke: a systematic review and meta-analysis.

Repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS) are noninvasive brain stimulation (NIBS) techniques able to modulate cortical excitability.

Efficacy and mechanisms of non-invasive brain stimulation to enhance exposure therapy: A review.

Though cognitive behavioral techniques are generally effective in the treatment of anxiety disorders, some people fail to benefit from exposure therapy or experience a return of fear after terminating exposure therapy. The burgeoning field of non-invasive brain stimulation provides a potential method of augmenting exposure therapy so that it is more effective. Successful exposure therapy is hypothesized to occur due to inhibition, and research suggests that brain stimulation can alter inhibitory learning an...

Robust clinical benefit of multi-target deep brain stimulation for treatment of Gilles de la Tourette syndrome and its comorbidities.

Habenula deep brain stimulation for refractory bipolar disorder.

Autonomic arousal elicited by subcallosal cingulate stimulation is explained by white matter connectivity.

Subcallosal cingulate deep brain stimulation (SCC DBS) is an experimental treatment for severe depression. Surgery is performed with awake patients and intraoperative stimulation produces acute behavioral responses in select contacts. While there have been reports on the relationship between acute intraoperative behaviors and their relation to the location of the contacts, there are no descriptions of the physiological changes that accompany them.

To determine the effect of two neuromuscular electrical stimulation (NMES) periods on quadriceps strength (QS) and functional performance in nursing home residents.

Safety of transcranial focused ultrasound stimulation: A systematic review of the state of knowledge from both human and animal studies.

Low-intensity transcranial focused ultrasound stimulation (TFUS) holds great promise as a highly focal technique for transcranial stimulation even for deep brain areas. Yet, knowledge about the safety of this novel technique is still limited.

Exploring the clinical outcomes after deep brain stimulation in Tourette syndrome.

Deep brain stimulation (DBS) of the thalamic centromedian-parafascicular (CM-Pf) region is the most common target to treat refractory Tourette syndrome (TS), but the improvement among the patients is quite variable. This study describes the outcomes of stimulation in TS patients and attempts to determine whether the volume of tissue activated (VTA) inside the thalamus or the structural connectivity between the area stimulated and different regions of the brain is associated with tic improvement.

Safety of transcranial direct current stimulation in a patient with deep brain stimulation electrodes.

Transcranial direct current stimulation (tDCS) has been investigated in movement disorders, making it a therapeutic alternative in clinical settings. However, there is still no consensus on the most appropriate treatment protocols in most cases, and the presence of deep brain stimulation (DBS) electrodes has been regarded as a contraindication to the procedure. We recently studied the effects of cerebellar tDCS on a female patient already undergoing subthalamic nucleus deep brain stimulation (STN-DBS) for g...

Network-basis of seizures induced by deep brain stimulation: Literature Review and Connectivity Analysis.

While transient, self-limiting seizures are an infrequent but known complication of deep brain stimulation (DBS) implantation surgery, stimulation itself has occasionally been reported to result in seizure activity at delayed timepoints. The neural circuitry implicated in stimulation-induced seizures is unknown. We report a case of seizure in a 47-year-old female with chronic subcallosal cingulate (SCC) DBS for treatment of refractory anorexia nervosa (AN) occurring with stimulation onset. Supratherapeutic ...

Deep brain stimulation for movement disorders.

Deep brain stimulation (DBS) is a treatment which uses high-frequency electric stimulation to suppress pathological brain activity. DBS has been applied for over 30 years now, particularly in patients with severe movement disorders, such as Parkinson's disease, dystonia and tremor. Although there is clearly scientific evidence for the effectiveness of DBS in these three movement disorders, the effect size of the treatment remains limited. Furthermore, DBS is not curative and can only be applied in a select ...

Postmortem Dissections of Common Targets for Lesion and Deep Brain Stimulation Surgeries.

The subthalamic nucleus (STN), globus pallidus internus (GPi), and pedunculopontine nucleus (PPN) are effective targets for deep brain stimulation (DBS) in many pathological conditions. Previous literature has focused on appropriate stimulation targets and their relationships with functional neuroanatomic pathways; however, comprehensive anatomic dissections illustrating these nuclei and their connections are lacking. This information will provide insight into the anatomic basis of stimulation-induced DBS b...

Sphenopalatine Ganglion Stimulation is a Reversible and Frequency-Dependent Modulator of the Blood-Brain Barrier.

The sphenopalatine ganglion (SPG) is a vasoactive mediator of the anterior intracranial circulation in mammals. SPG stimulation has been demonstrated to alter blood-brain barrier (BBB) permeability, although this phenomenon is not well characterized.

Interleaving stimulation in Parkinson's disease: interesting to whom?

Interleaving stimulation (ILS) is an available stimulation strategy that can help the physician manage more challenging cases of patients with deep brain stimulation (DBS) for Parkinson's disease. (PD) It consists in altering two different programs on the electrode with the same frequency.

Noninvasive Brain Stimulation for Rehabilitation of Paediatric Motor Disorders Following Brain Injury: Systematic Review of Randomized Controlled Trials.

To assess the evidence of the effectiveness of noninvasive brain stimulation (NIBS) for rehabilitation of paediatric motor disorders after brain injury.

Characterizing and minimizing the contribution of sensory inputs to TMS-evoked potentials.

Transcranial magnetic stimulation (TMS) evokes voltage deflections in electroencephalographic (EEG) recordings, known as TMS-evoked potentials (TEPs), which are increasingly used to study brain dynamics. However, the extent to which TEPs reflect activity directly evoked by magnetic rather than sensory stimulation is unclear.

Enhanced neuronal activity in mouse motor cortex with microbubbles' oscillations by transcranial focused ultrasound stimulation.

Microbubbles (MBs) are known to serve as an amplifier of the mechanical effects of ultrasound, which combined with ultrasound are widely used in brain. The goal of this study is to investigate the effect of oscillating MBs on the neuronal activity in the central nervous system (CNS) of mammals. The motor cortex of mice brain was subjected to ultrasound stimulation with and without MBs, and evoked electromyogram signals were recorded. A c-fos immunofluorescence assay was performed to evaluate the neuronal ac...

No effects of anodal transcranial direct current stimulation on contrast sensitivity function.

Transcranial direct-current stimulation (tDCS) is a well-established non-invasive brain stimulation technique that has been widely applied to modulate cortical excitability in human brain. The results of previous tDCS studies on modulating contrast sensitivity, one of the most fundamental visual functions, were mixed.

Cortical network fingerprints predict deep brain stimulation outcome in dystonia.

Deep brain stimulation (DBS) is an effective evidence-based therapy for dystonia. However, no unequivocal predictors of therapy responses exist. We investigated whether patients optimally responding to DBS present distinct brain network organization and structural patterns.

Deep brain stimulation modulates hypothalamic-brainstem fibers in cluster headache: case report.

Hypothalamic deep brain stimulation (DBS) has been used for more than a decade to treat cluster headache (CH) but its mechanisms remain poorly understood. The authors have successfully treated a patient with CH using hypothalamic DBS and found that the contact used for chronic stimulation was located in a white matter region posterior to the mammillary bodies. Fiber tracts crossing that region were the medial forebrain bundle and those interconnecting the hypothalamus and brainstem, including the dorsal lon...

Cochlear implantation with deep brain or occipital nerve stimulation : Case studies for parallel application.

We were able to demonstrate that simultaneous treatment of a patient with a neuromodulation device for deep brain stimulation (DBS) or occipital nerve stimulation (ONS) plus a cochlear implant is a possible treatment option, and that both systems are able to work within their specifications without interference from each other. A large patient population with indications for both systems could profit from this in the future.

Deep brain stimulation in Parkinson's disease: A multicentric, long-term, observational pilot study.

The impact of deep brain stimulation (DBS) on cognitive and urinary disorders, falls, and eventually hospitalizations and mortality in Parkinson's disease (PD) is still debated.

Pilot trial of home-administered transcranial direct current stimulation for the treatment of depression.

Transcranial Direct Current Stimulation (tDCS) is a non-invasive, neuromodulation approach with promising efficacy for treating depression. To date, tDCS has been limited to clinical or research centre settings with treatment administered by staff. The aim of this study is to examine the efficacy, tolerability and feasibility of home-administered, remotely-supervised tDCS for depression.

Can neuromodulation techniques optimally exploit cerebello-thalamo-cortical circuit properties to enhance motor learning post-stroke?

Individuals post-stroke sustain motor deficits years after the stroke. Despite recent advancements in the applications of non-invasive brain stimulation techniques and Deep Brain Stimulation in humans, there is a lack of evidence supporting their use for rehabilitation after brain lesions. Non-invasive brain stimulation is already in use for treating motor deficits in individuals with Parkinson's disease and post-stroke. Deep Brain Stimulation has become an established treatment for individuals with movemen...
