Parkinson's disease (PD) is the second largest neurodegenerative disorder worldwide. This disease results from the loss of dopamine producing neurons in parts of the basal ganglia of the brain. Previous studies have shown the involvement of the dopamine system in the basal ganglia in balance control. Sensations of balance in the body are detected by the vestibular apparatus. In this project, electrovestibulography...
Functional coupling of regional cerebral metabolic rates for glucose measured with [ 18 F]-Fluoro-2-deoxy-D-glucose PET was compared in 18 drug-free patients with Tourette's Syndrome (TS) and 16 age- and sex-matched control subjects. Pearson product-moment correlation matrices containing correlations between metabolic rates in regions sampled throughout the brain were generated independently...
This article reviews neuronal activity related to reward processing in primate and human brains. In the primate brain, neurophysiological methods provide a differentiated view of reward processing in a limited number of brain structures. Dopamine neurons respond to unpredictable rewards and produce a global reinforcement signal. Some neurons in the striatum also react to the expectation and detection...
