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.
Expected learning outcomes
Students will know the methods, the insights, and the questions of the neurobiology, achieving a theoretical background to study the brain and its pathologies.
Course syllabus and organization

Single session

Responsible
Lesson period
Third trimester
All classes planned during the third trimester of the first year of the Master Degree Medical Biotechnology and Molecular Medicine, will be given as frontal teaching and distance synchronous learning. In case of a new suspension of frontal lectures, all students will be asked to move to distance synchronous learning.
Each hour of lesson will be divided into 45' of formal teaching followed by 15' of discussion/interaction/question time. All lessons will be recorded and made available for students on the indicated platforms (i.e. Ariel, TEAMS, etc).
Unless otherwise specified, exams will be organized in classroom but if the student is unable to reach the building for COVID-related issues, other forms will be considered (this apply for exams scheduled until the 31st July - 2021).
Course syllabus
Neurology:
Wiring of the nervous system. Neurogenesis, migration, specificity. Signals from target cells. How 20.000 genes specify 10^14 connections?

Wiring of the visual system.
Biochemistry:
Functional relevance of glycoconjugates in the physiology and pathology of the nervous system.
Metabolism, traffic and cellular topology of glycoconjugates in neural cells. Glycoconjugates in synaptic function, in neuron-glia communication, in myelin formation and stabilization. Altered glycoconjugates metabolism and functions in neurogenerative and demyelinating diseases.
