Neurobiology
A.Y. 2020/2021
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.
Lesson period: Third trimester
Assessment methods: Esame
Assessment result: voto verbalizzato in trentesimi
Single course
This course cannot be attended as a single course. Please check our list of single courses to find the ones available for enrolment.
Course syllabus and organization
Single session
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).
