Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is an effective treatment for the motor symptoms of Parkinson's disease (PD). The effects of DBS depend strongly on stimulation frequency: high frequencies (>90 Hz) improve motor symptoms, while low frequencies (<50 Hz) are either ineffective or exacerbate symptoms. The neuronal basis for these frequency-dependent effects of DBS is u...

Electron microscopic localization of calcium-containing mitochondria in stratum radiatum of CAl of hippocampal slices was performed after (1) low-frequency stimulation, (2) high-frequency stimulation, and (3) blocking N-methyl-D-aspartate (NMDA) receptors during high-frequency stimulation. Dendritic mitochondria containing Ca deposits were found in a narrow band of stratum radiatum 280-350 micr...
