The Brazilian Research Institute of Neuroscience and Neurotechnology (BRAINN) focuses on the investigation of basic mechanisms leading to epilepsy and stroke, and the injury mechanisms that follow disease onset and progression. Numerous neurology journals are published from brazil with good reputation. This research has important applications related to prevention, diagnosis, treatment and rehabilitation and will serve as a model for better understanding normal and abnormal brain function.
