Directional DBS system targets GPi to relieve Parkinson’s symptoms

Abbott received FDA approval for an expanded indication for its Deep Brain Stimulation system, to include targeting of internal globus pallidus. The GPi plays an integral role in motor function. When targeted with DBS, Parkonson’s symptoms not adequately controlled by medication can improve. The directed stimulation system is now approved for all major targets used […]

High resolution brain map traces wiring within, between, thalamus and cortex

Allen Institute scientists have created a high-resolution brain map, which traces thousands of connections between brain areas in mice, which they believe  can help us understand how brain circuitry changes in diseases and disorders such as Alzheimer’s disease and schizophrenia. This is the most detailed map of connections in a mammalian brain to date, tracing neural […]

DBS study shows long-term antidepressant effect in treatment-resistant depression

Helen Mayberg at Mount Sinai has published a study showing that deep brain stimulation of the subcallosal cingulate provides a lasting antidepressant effect in treatment-resistant depression. According to Mayberg: “Over eight years of observation, most of our study participants experienced an antidepressant response to the deep brain stimulation of Area 25 that was robust and […]

Implanted electrodes + algorithm allow thought-driven 4 limb exoskeleton control

Alim Louis Benabid and Clinatec/University of Grenoble colleagues have developed a brain computer interface controlled exoskeleton that enabled a tetraplegic man to walk and move his arms.  Two 64 electrode brain implants drove the system. Benabid explained the benefits, stating that “previous brain-computer studies have used more invasive recording devices implanted beneath the outermost membrane of the […]
