Several diseases are known to have a multifactorial origin, depending not only on genetic but also on environmental factors. They are called "complex disorders" and include cardiovascular disease, cancer, diabetes, and neuropsychiatric and neurodegenerative diseases. In the latter class, Alzheimer's (AD) and Parkinson's diseases (PD) are by far the most(More)
Alzheimer's disease (AD) is the most common age-related neurodegenerative disorder among the elderly. Nmethyl- D-aspartate receptor (NMDAR) overactivation has been implicated in early synaptic dysfunction that precedes late neurodegeneration in AD. Moreover, oligomers of amyloid-beta peptide (Aβ) 1-42 are considered the most synaptotoxic forms, responsible(More)
Neurodegenerative diseases (e.g. Alzheimer's disease, Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis and prion-related diseases) have in common the presence of protein aggregates in specific brain areas where significant neuronal loss is detected. In these pathologies, accumulating evidence supports a close correlation between(More)
Acquisition of new perceptual-motor skills depends on multiple brain areas, including the striatum. However, the specific contribution of each structure to this type of learning is still poorly understood. Focusing on the striatum, we proposed (a) to replicate the finding of impaired rotary pursuit (RP) and preserved mirror tracing (MT) in Huntington's(More)
