Invited by Dr Todor Gerdjikov.

Parkinson's disease (PD) is characterized by the presence of abnormal oscillatory activity at different points of the basal ganglia. In the subthalamic nucleus (STN), the most commonly structure studied in PD patients, activities in the theta, beta, gamma and high-frequency (300 Hz) ranges have been described. Beta activity has been shown to have a correlation with clinical symptoms, like rigidity and bradykinesia. Low frequency oscillations have been associated with different drug side-effects and a dependence of the amplitude of fast frequencies on the phase of slower frequencies have been recently described.

In this talk Dr Ustárroz will review some of these findings with a focus on the different signal processing techniques used to evaluate how brain oscillatory activity is altered both in PD patients and in animal models of the disease. The event will take place on Thursday 21st November 4pm, Frank & Katherine May Lecture Theatre, Henry Wellcome.
