INTEGRATIVE NEUROPHYSIOLOGY

The course is one of the educational activities of the Physics of the Brain curriculum of the Master's Degree Course in Engineering Physics and allows students to acquire knowledge and understanding of the fundamental and applicative concepts of neurophysiology.

The course aims to ensure that students acquire:
1) Knowledge and understanding, possessing a thorough knowledge of the fundamental principles underlying the different, but fundamental, aspects of neuronal integration at several levels of the central nervous system. These will comprise different aspects, from the integrative processes which are carried on by neuronal membranes to neuronal networks, till to the more actual approaches to study the activity of the living brain.
2) Applying knowledge and understanding, acquiring the theoretical basis for understanding the most basic procedures related to the acquisition of the most sophisticated biological information from a living brain.
3) Making judgment, acquiring a correct vision of the functioning of the nervous system, with particular emphasis on the basic processes of integration, both at cellular and systemic level.
4) Communication skills, getting used to the exhibition, in the classroom, of the concepts requested by the teacher, in a stimulated and interactive teaching environment. Students will always be urged to keep in mind the need for scientifically rigorous exposure and communication with colleagues and the general public. They will be stimulated to express themselves in a correct and essential language.
5) Learning skills. At the end of the course the students will possess knowledge and critical reading abilities to continue their training independently, adapting themselves to new knowledge and technologies in the understanding of the integrative processes acting in the brain.

Knowledge of fundamental cell biology and cell physiology in the central nervous system.

The course is organized in different independent modules and two teachers contribute to them with specific competences. The program is aimed at providing wide information on the more actual approaches to study the activity of the living brain and on fundamental aspects of neuronal integration, from the integrative processes which are carried on by neuronal membranes to neuronal networks.
Main topics which will be presented.
Part 1: Membrane biophysics and cell excitability. Brain waves generation and oscillatory mechanisms. Thalamo-cortical rhythms, spindle waves and delta waves. Role of particular membrane properties, such as voltage dependent ion channels, or synaptic properties. Role of voltage dependent ion channels. Thalamo-cortical rhythm.
Part 1: Long term plasticity (LTP): from Hebb’s postulate to electrophysiological and behavioral evidence. NMDA receptor- dependent LTP. Spike timing dependent plasticity. Anti-Hebbian LTP. Depolarizing GABA in early development and its implication for synaptic plasticity. Functional implications of hippocampal synaptic plasticity: memory and learning. Plastic changes in the amygdala circuitry. An example of associative learning: the fear conditioning paradigm. Cellular mechanism underlying fear extinction. Zebrafish as alternative model to study synaptic plasticity in whole organism.
