Subthalamic nucleus physiology is correlated with deep brain stimulation motor and non-motor outcomes.

Subthalamic nucleus deep brain stimulation is commonly indicated for symptomatic relief of idiopathic Parkinson's disease. Despite the known improvement in motor scores, affective, cognitive, voice and speech functions might deteriorate following this procedure. Recent studies have correlated motor outcomes with intraoperative microelectrode recordings.

Can the RAVLT predict deterioration from MCI to dementia? Data from long term follow up.

Objective: To assess whether the Rey Auditory Verbal Learning Test (RAVLT) could differentiate deterioration from Mild Cognitive Impairment (MCI) to dementia.

Methods: Twenty-six participants who were diagnosed with MCI performed the RAVLT and the Mini Mental State Examination (MMSE) at baseline and after nearly a decade (M = 8.8 years, SD = 3.

Spatial distribution and hemispheric asymmetry of electrically evoked experiential phenomena in the human brain.

Objective: Experiential phenomena (EP), such as illusions and complex hallucinations, are vivid experiences created in one's mind. They can occur spontaneously as epileptic auras or can be elicited by electrical brain stimulation (EBS) in patients undergoing presurgical evaluation for drug-resistant epilepsy. Previous work suggests that EP arise from activation of different nodes within interconnected neural networks mainly in the temporal lobes.
