Learning objectives
The course of Neurobiology is intended to offer an integrated view of the nervous system, from the cellular and molecular basis of neural excitability and synaptic transmission, to the neuronal networks and the complex hierarchical organization of the brain and behavior. The molecular understanding at the cellular level is integrated to higher brain functions such as mechanisms of sensory perception, reflexes and motor function, learning, memory, and biorhythms.
Students will know the methods, the insights, and the questions of the neurobiology, achieving a theoretical background to study the brain and its pathologies.
