The effects of the therapy in a small group of  patients were long-lasting, researchers say, adding to evidence that the approach works for treatment-resistant depression.

The result of a study among patients with epilepsy strengthens the case for the importance of this brain region in determining mood.

Studies have demonstrated that magnetic and electrical currents can enhance memory in human subjects, but the technology is not yet ready for prime time.

One patient with diabetes was able to reduce his medication use while receiving targeted electrical pulses.

Researchers develop a new technique to selectively activate neurons deep in the rodent brain, taking a step toward noninvasive brain stimulation for neurological disorders.

With a clinical trial underway to restore vision optogenetically, researchers also see promise in using the technique to treat deafness, pain, and other conditions.

Using interfering high-frequency currents applied to the surface of the mouse skull, scientists can noninvasively target brain regions buried below the cortical surface. 

Deep-brain stimulation may effectively treat slow movement, tremor, and rigidity in Parkinson’s patients by reducing synchronicity of neural activity in the motor cortex.

Neurosurgeon Andres Lozano discusses deep-brain stimulation in this TEDx talk.

Deep-brain stimulation is allowing neurosurgeons to adjust the neural activity in specific brain regions to treat thousands of patients with myriad neurological disorders.

Brain-implant technologies just got a vote of government confidence, as the Defense Advanced Research Projects Agency announces an investment of $70 million over five years.
