The purpose of this study is to track seizure occurrence, seizure probability, behavioral state, cognition, and mood using an implantable brain sensing and stimulation device (Medtronic RC+S Summit) coupled to an external, handheld, patient assistant device (PAD) with capability for patient interaction (patient data input). The system (RC+S & PAD) provides intracranial EEG (iEEG) sensing, electrical brain stimulation, and machine learning algorithms running on the RC+S and PAD that will be coupled with electrical brain stimulation (EBS) to prevent seizures and improve quality of life in patients with epilepsy

This study is designed to evaluate the high-frequency range deep brain oscillations (HFO) as pathologic markers in patients undergoing deep brain stimulation for epilepsy or Parkinson disease. Newly developed technology allows for the chronic recording of these brain signals at the same time as clinical stimulation is occuring. We will learn both whether these HFO correlate with disease activity and whether the HFO change in response to ongoing stimulation (potentially giving insight into the underlying mechanism of action of DBS). Study participants will undergo DBS in the same way as is usually done but will receive this newer battery with ...

The purpose of this study is to evaluate the safety, and feasibility of adjuvant high frequency stimulation of the GPe using Deep Brain Stimulation.

The purpose of this study is to examine the long term effects of motor cortex stimulation related to pain control.

The purpose of this study is to compare 7 tesla MRI data and 3D image of model deep brain stimulation target areas to the post-surgical image of actual placement at time of deep brain stimulation surgery, using standard of care 1.5 tesla MRI.

The overall purpose of this study is to evaluate the effectiveness and safety of brain stimulation techniques currently used for clinical patient care. To determine the likelihood of improvements in seizure frequency, neurological symptoms, and quality of life after treatment with brain stimulation in certain populations, as well as evaluate for any beneficial or deleterious side effects from these modalities. In addition, in instances were brain stimulation was used for diagnostic purposes such as with cortical mapping via TMS, outcomes will be compared to other results already available in the electronic medical record system (e.g., MRI).

The purpose of this study is to provide feasibility data for a novel method of defining patient-specific functional anatomic targets for Globus Pallidus Internus (GPi) Deep Brain Stimulation (DBS) placement.

The purpose of this study is to investigate the feasibility and safety of thalamic CL stimulation in restoring consciousness in epilepsy patients.

The purpose of this study is to demonstrate that the RNS® system is safe and effective as an adjunctive therapy in individuals age 12 through 17 with medically refractory partial onset epilepsy.

Does dual hemispheric stimulation of the subthalamic nucleus (STN) and fornix/hypothalamus potentially improve cognitive function in patients with Parkinsons disease.

The purpose of this study is to assess the safety and effectiveness of a Cala TWO Device on brain metabolism in essential tremor subjects scheduled to undergo deep brain stimulation surgery.

The purpose of this study is to assess how the overall impact of pain has changed in the patient's life since deep brain stimulation surgery.

The aim of this feasibility study is to investigate whether we can improve sleep quality in patients who have DBS devices implanted for existing neurological indications by delivering targeted stimulation patterns during specific stages of sleep using their existing DBS device. We will only use electrical stimulation frequencies that have been proven to be safe for patients. We will perform these studies in patients admitted to the hospital in order to examine the structure and quality of sleep as well as how alert patients are when they wake up, while also monitoring physiological markers such as brainwave activity, ...

The purpose of this study is to investigate the effects of subthalamic nucleus and globus pallidus interna deep brain stimulation on bowel symptoms and the ability to smell things in patients with Parkinson disease and constipation.

The purpose of this study is to evaluate the safety and effectiveness of Boston Scientific's Vercise Deep Brain Stimulation (DBS) system in the treatment of patients with with advanced, levodopa-responsive bilateral Parkinson's disease (PD) which is not adequately controlled with medication.

The purpose of this post-approval study is to further evaluate the long-term safety and effectiveness of Medtronic DBS therapy for epilepsy on seizure reduction in newly implanted participants through 3 years of follow-up in different geographic populations.

The proposed study seeks to obtain preliminary signal of the tolerability and efficacy of transcranial direct current stimulation (tDCS) for depressive symptoms in a sample of adolescents with depression and epilepsy. Additionally, effects of tDCS will be assessed via electroencephalographic, cognitive, and psychosocial measures.

The purpose of this study is to gather information regarding the use of rTMS as a treatment for depression in adolescents with Major Depressive Disorder. The investigators also hope to learn if measures of brain activity (cortical excitability and inhibition) collected with transcranial magnetic stimulation (TMS) can be used to identify which patients will benefit from certain types of rTMS treatment. 

The primary purpose of this study is to understand how epilepsy patients think about neuromodulation in relation to concepts of neuroexceptionalism and the self.
