Zusammenfassung
Objective: We have previously shown that the human subthalamic area (SA) is active during emotional processing as indexed by an event related desynchronisation (ERD) of local field potential (LFP) activity in the alpha frequency range (7–12Hz) at 1–2 seconds after stimulus presentation (Kühn et al., 2005). It remains however unclear if the alpha ERD is related to stimulus-induced arousal reaction or valence discrimination. Here, we aim at disentangling the respective impact of these two aspects of emotional processing on subthalamic activity in patients with Parkinson's disease (PD). Methods: LFPs were recorded…
