Like the striatum, the frontal motor cortices receive dopaminergic ®bers from midbrain dopamine cells and contain high levels of dopamine receptors. Among frontal cortical areas, the dorsolateral PFC (PFd1) and the dorsal premotor cortex (PMd) have strong neural connections and play a major role for working memory-guided directional movements. To reveal the role of dopamine in this cognitive mo...

Water-soluble derivatives of buckminsterfullerene (C60) derivatives are a unique class of compounds with potent antioxidant properties. Studies on one class of these compounds, the malonic acid C60 derivatives (carboxyfullerenes), indicated that they are capable of eliminating both superoxide anion and H2O2, and were effective inhibitors of lipid peroxidation, as well. Carboxyfullerenes demonst...
