Scientists Demonstrate Flexible Brain Probe in Preclinical Work

Oct. 6, 2015 - A paper in Nature Materials describes how laboratory research with electrodes in a polymer mesh allowed scientists to monitor individual neurons in a rat, locating the region of the cortex associated with movement of a single whisker. The mesh forms a cylinder that was stiffened temporarily by dipping into liquid nitrogen prior to inserting into the rat's brain. When not in that chilled state, the authors say, the mesh is up to seven orders of magnitude less stiff than conventional probes, which they believe would make the sensor array less likely to induce scarring. Also, the article states that the array should be more likely to move as the brain shifts during day-to-day movement, so sensors would be more likely to continuously sample the same part of the brain.

Review: Deep Brain Stimulation Addresses Circuit Disorders

Sept. 26, 2015 - A review of deep brain stimulation (DBS) in movement disorders and conditions such as obsessive compulsive disorder, which are considered a circuit disorder involving the basal ganglia, presents surgical interventions as highly focused approaches that spare uninvolved areas, unlike systemic medications.

Study Explores Protective Effect of Deep Brain Stimulation in Epileptic Rats

Sept. 4, 2015 - A group of collaborators has published results of a laboratory study in which deep brain stimulation (DBS) was shown to induce cell-protective and anti-inflammatory effects in rats who underwent epileptic seizures. The researchers say although a direct causal relationship cannot be established, they did find DBS influenced certain pro-inflammatory cytokines and they observed reduced neuronal death. While loss of neurons is usually attributed to excitotoxicity after a seizure, they say, inflammation may play a role. In addition, spectral analysis indicated DBS may have decreased the severity of the seizure, compared to controls. (Journal of Neuroinflammation)

The network could provide a foundational architecture with interoperability solutions for incorporating data from non-registry sources, such as unique device identifiers when they are implemented; electronic health records; administrative claims data; and mobile device outputs. The task force said the data should include information that may not all be captured in existing registries, such as device and procedural details, patient descriptors, and long-term outcomes.

How Has Neuromodulation Been Developed and Used?

Conventional medicine has typically had four modes of treating diseases or disorders: counseling or “talk therapy”; physical therapy involving manipulation and strengthening of muscles and range of motion; pharmaceuticals that act on a chemical level; and altering or augmenting tissue through surgery, injections, or filtering methods like dialysis. The growing field of neuromodulation is a new class of therapies that involves directly treating the nervous system itself, often through small implanted devices that target a specific area, to rebalance the activity of neural circuits and manage symptoms.

Progress has been spurred by advances in our understanding of the nervous system, as well as new technologies and clinical experience, enabling treatments to modify nerve cell activity in brain, spinal cord and periphery to restore function, minimize pain, and treat disease symptoms. Developed over the last 45 years, neuromodulation has grown rapidly into a family of therapies that applies stimulation or agents directly to the nervous system, often using small implanted medical devices that are powered in a similar fashion to a cardiac pacemaker. By delivering electrical or chemical stimulation, neuromodulation has increasingly been used to treat motor disorders such as Parkinson’s disease, refractory chronic pain ranging from neuropathy to cancer related pain to severe headaches, spasticity, epilepsy, and incontinence. It is also under study for conditions ranging from gastroparesis to medically refractory depression. Providers of such therapies include neurosurgeons, pain physician specialists and rehabilitation physicians. They may often work with other specialists such as neurologists, psychiatrists, psychologists, gastrointestinal or colorectal specialists, urologists, primary care physicians, and physical therapists to achieve best outcomes.

The International Neuromodulation Society (INS) is a non-profit group of clinicians, scientists and engineers dedicated to the scientific development and awareness of neuromodulation - the alteration of nerve activity through the delivery of electrical stimulation or chemical agents to targeted sites of the body. Founded in 1989 and based in San Francisco, CA, the INS educates and promotes the field through meetings, its peer-reviewed journal Neuromodulation: Technology at the Neural Interface, explanatory content, and chapter websites.
