Deep Brain Stimulation for Tourette Syndrome
… (TS). The International Tourette Syndrome Deep Brain Stimulation (DBS) Public Database and Registry is a multinational collaborative effort designed to share data and improve the quality of outcomes research in the treatment of TS with DBS. , recently described by Martinez-Ramirez et al in JAMA …

Brain stimulation reveals neural mechanisms of stereopsis
… of this problem and solutions that the brain applies. To study brain function, I use Transcranial Magnetic Stimulation (TMS) which allows me to causally relate induced changes in neural activity with changes in depth perception. This way I can map out neural mechanisms of stereopsis …

Understanding Autonomic Control via Human Deep Brain Stimulation
… of higher cortical areas, basal ganglia, and brainstem areas that are important in the control of the autonomic nervous system (ANS). This thesis concentrates on the control of the respiratory and cardiovascular systems both alone and in combination in the context of exercise. Deep Brain …

Digitally-Controlled Deep Brain Stimulation Lead Implant System
<p>Deep brain stimulation, the treatment of disorders by applying electrical stimulation to brain tissue, is a relatively new field of medicine with great potential to provide cures for neurological disorders. It utilizes a system very similar to a cardiac pacemaker and lead to electrically …

Working memory training and transcranial electrical brain stimulation
… Evidence has shown that transcranial electrical stimulation (tES) may be an effective tool for enhancing cognitive training and promoting transfer. In the first study, participants completed Cogmed working memory training with either active or sham transcranial random noise stimulation (tRNS). …

Analysis and Design of Electrodes for Deep Brain Stimulation
<p>Deep brain stimulation (DBS) electrodes are intended to stimulate specific areas of the brain to treat movement disorders including essential tremor, Parkinson's disease and dystonia. An important goal in the design of next generation DBS electrodes is to minimize the power needed to stimulate …

Sparking controversy : the contested use of noninvasive brain stimulation
… the controversy over transcranial direct current stimulation (tDCS), a noninvasive form of brain stimulation that is thought to provide a constant low level of electrical current to the brain. Although scientists have been experimenting with tDCS in both healthy and clinical populations for the …

Behavioral Pharmacological Analysis of Deep Brain Stimulation Following Nerve Injury
Treatment of neuropathic pain remains a major unmet public health problem. Serious concerns arise over misuse of prescription opioids in chronic pain patients, a drug class representing the fastest growing substance abuse problem in the United States. Ascending pain pathways overlap significantly …

Non-Invasive Brain Stimulation and the Enhancement of Working Memory
… research is the use of transcranial current stimulation, specifically transcranial direct current stimulation (tDCS), as a cognition enhancer. The present study seeks to address three questions: (1) is there a separate working memory system for music distinct from verbal working memory, (2) …

Nicotine withdrawal causes transient elevations in brain stimulation reward thresholds
… motivation to respond for rewarding electrical brain stimulation. It has been proposed that such attenuation of brain stimulation reward reflects opponent-process depression of brain reward circuitry and underlies the dysphoric symptoms of drug withdrawal in humans. In the present study the …

Invasive and Noninvasive Brain Stimulation Strategies for the Treatment of Tinnitus
… ascending auditory system. Further, by combining stimulation of auditory cortex with an irrelevant acoustic stimulus, we were able to suppress neural firing throughout the inferior colliculus, revealing at least one potential mechanism for gating relevant versus irrelevant sound inputs. Targeting …

Towards Closed-Loop Deep Brain Stimulation: Behavior Recognition from Human STN
<p>Deep brain stimulation (DBS) provides significant therapeutic benefit for movement disorders such as Parkinson’s disease (PD). Current DBS devices lack real-time feedback (thus are open loop) and stimulation parameters are adjusted during scheduled visits with a clinician. A closed-loop DBS …

Effects of selective neurotensin receptor antagonists on responding for brain stimulation reward
Electrical stimulation of the medial mesencephalic central gray produces a strong rewarding effect, and laboratory animals can easily be trained to produce an operant response to obtain such a stimulation. Previous studies have shown that the rewarding effect of mesencephalic electrical stimulation …

Balance performance in people with Parkinson’s disease. Effects of subthalamic Deep Brain Stimulation.
… aims of this work were to investigate if Deep Brain Stimulation in the subthalamic nuclei (STN) affected balance, fear of falling and falls in people with Parkinson's disease. The effect of STN stimulation alone was investigated in Papers I, II and III. The participants were evaluated after an …

Characterization of the synergistic effects of cocaine with lateral hypothalamic brain stimulation reward
… rewarding in humans and lower animals. The brain stimulation reward paradigm offers an interesting tool with which to study the reward-relevant actions of cocaine. Cocaine potentiates the rewarding impact of brain stimulation; the stimulation is thought to exert its reward-relevant effects …

Mapping the substrate for brain stimulation reward : new approaches to an old problem
A major goal for research on brain stimulation reward (BSR) is the identification of the directly-activated ("first-stage") neurons subserving the powerfully rewarding effect produced by electrical stimulation of the medial forebrain bundle (MFB). This objective was addressed by combining …

Brain Stimulation Reward is Integrated by A Network of Electrically-Coupled GABA Neurons
… electric current to various diverse brain structures, the neural substrate of brain stimulation reward (BSR) has eluded identification since its discovery more than a half-century ago. We show that GABA neurons in the midbrain, hypothalamus and thalamus express connexin-36 (Cx36) gap …

Your brain on 9 volts : the specter and hype of electrical brain stimulation
The potential of electricity to improve the brain has captivated many. Electrical gadgets attract the rich and the poor, the educated and uneducated, the scientist and the charlatan. Over hundreds of years, people have tried everything from shocking away headaches with live torpedo fish, to …
