The recommended texts will be integrated with additional material indicated during the lectures

The course aims to acquire and deepen the knowledge of biophysics and molecular and cellular physiology with particular reference to the nervous system. Students will acquire the understanding of the mechanisms associated with transport processes, membrane bioelectric phenomena and cell signaling. They will be able to describe and illustrate, with appropriate scientific language, the contents of the course in a logical and complete manner, being able to make connections between the various topics and to apply the acquired knowledge in the fields of pharmacology and pharmaceutic technology.

Students must have basic knowledge of mathematics and statistics, physics, biochemistry, molecular biology and physiology.

Theoretical lectures and laboratory exercises. In case of the COVID-19 emergency, the lessons will be held at a distance using e-learning technologies, according to the schedule and modality indicated by the administration.

Students with physical disabilities, Learning Disabilities or Special Education Needs can request specific services and tools via the Staff Sviluppo e Coordinamento Carriere e Servizi alle Studentesse e agli Studenti, consulting the University webpage: https://www.uniupo.it/en/services/services-students-physical-or-learning-disabilities Students with disabilities, learning disabilities or special education needs, once they have contacted the University Staff, can refer to the tutor in charge of the course to define the examination modalities, concerning academic aspects.
