Educational objectives The main purpose of this course is to provide the fundamental knowledge on the physiopathological bases of neurological diseases. Moreover, the program will focus on the molecular and synaptic mechanisms underlying some neurological diseases, such as Parkinson’s, Huntington’s, and Alzheimer’s, multiple sclerosis, stroke, and epilepsy. The course provides also a practical approach on the use of electrophysiological techniques (extra-, intra-, and patch-clamp-cellular recordings) in experimental brain slice preparations.
Prerequisites Neuron biology basics.
Teaching methods Frontal lessons and practical exercises.
Other information Frequency not mandatory but strongly recommended.
Learning verification modality Written test and final oral exam.
