Název v původním jazyce

Participation of the subthalamic nucleus in executive functions: An intracerebral recording study.

Popis výsledku v původním jazyce

The objective of our work was to find whether the subthalamic nucleus (STN) is directly involved in cognitive activities, specifically in executive functions. Ten patients with idiopathic Parkinson's disease had P3 potentials recorded by externalized deep brain electrodes that were implanted in the STN or in its immediate vicinity. Two contacts of each electrode were positioned inside the STN according to clinical effect, perioperative microrecording, and stimulation. The P3 waves were recorded following the auditory stimulus in a standard oddball paradigm. They were compared with the P3 waves elicited from a protocol modified by a dual task with an increased demand on executive functions. The P3 potentials with a steep amplitude gradient evoked by themodified protocol were detected by the contacts in 8 of the 14 available electrodes, located either inside the STN or in its immediate vicinity. The modified protocol led to an increased latency of the P3 potential in 8 of 14 electrodes.
