## Abstract Precise placement of the electrodes for stimulation of the subthalamic nucleus (STN) in Parkinson's disease (PD) is crucial for the therapeutic benefit. As a result of the mistargeting and misplacement of the electrodes during surgery in 2 patients with PD, we have characterized the neu

β¦ Synopsis
This study demonstrated a significant loss of neurons within the lateral part of the pedunculopontine nucleus pars compacta in individuals with idiopathic Parkinson's disease and in individuals with combined Parkinson's and Ah- heimer's disease. We also examined the extent of neuronal loss within the substantia nigra pars compacta, locus ceruleus, dorsal raphe nucleus, and nucleus basalis of Meynert. The number of pedunculopontine nucleus pars compacts neurons in the patients with Parkinson's or Parkinson's and Alzheimer's disease was reduced (average, 40%) in comparison with the number in control subjects or patients with Alzheimer's disease ( p < 0.01). This finding correlated significantly with the extent of loss of substantia nigra pars compacta neurons ( p < 0.01).

Microelectrode recordings of single unit neuronal activity were used during stereotactic surgery to define the subthalamic nucleus for chronic deep brain stimulation in the treatment of Parkinson's disease. By using five parallel trajectories, often two to three microelectrodes allow us to recognize
A representative region of the nucleus basalis of Meynert was investigated in 11 patients with idiopathic Parkinson's disease and compared with the identical region in 13 age-matched control subjects. Simultaneously, the cerebral cortex and the nucleus basalis i n the patients with Parkinson's disea
## Abstract We have previously shown that in patients with Parkinson's disease (PD), highβfrequency stimulation (HFS) of the subthalamic nucleus (STN) modifies spinal excitability via subcortical reticulospinal routes. To investigate whether STNβHFS also modifies spinal excitability via transcortic
Studying the clinical effects induced by electrical stimulation of the subthalamic nucleus (STN) area in a parkinsonian patient under local anesthesia is a mandatory step to determine the precise location of the final chronic electrode. Using multiple microelectrodes, preferably in a concentric para
