Electrophysiological analyses of PD rats treated by hydrogels. A Electrophysiological traces of subthalamic nucleus (STN) spikes in different condition treated PD rats within 10 s at 14 days. B Quantitative overall spike rates of each group from a 30-s period of each recording devoid of significant noise at 14 days. *p < 0.05, **p < 0.01, ***p < 0.001, and ****p < 0.0001 between the indicated groups
