The course aims to ensure that students achieve the following learning outcomes:
1) Knowledge and understanding: Students will gain a comprehensive understanding of the basic principles of neuronal integration at different levels of the central nervous system. This includes the integrative processes performed by neuronal membranes, neuronal networks, sensorimotor integration (such as reflexes and voluntary movement), and contemporary approaches to the study of brain activity.
2) Application of knowledge: Students will acquire the theoretical foundation to understand the basic procedures involved in abstracting the information acquired to more general cases.
3) Judgment: Students will develop a correct understanding of how the nervous system functions, with particular emphasis on the basic processes of integration at the cellular and systemic levels.
4) Communication skills: Students will become adept at presenting concepts in a stimulating and interactive classroom setting. They will be encouraged to maintain scientific rigor in their communication with peers and the general public. Emphasis is placed on expressing ideas in clear, appropriate, and concise language.
5) Study skills: By the end of the course, students will have the knowledge and critical reading skills necessary for independent learning. They will be able to adapt to new knowledge and technologies in the field of integrative processes in the brain.
Knowledge of fundamental cell biology, molecular biology, and cell physiology.
The objective of this course is to provide an up-to-date overview of the integration of neuronal activity in various neural systems of mammals and vertebrates.
The course will explore a range of integrative processes starting from fundamental neurophysiological functions of basic neuronal networks, and progressing to advanced topics like sensorimotor integration and movement production.
Key topics to be covered include: membrane biophysics and cell excitability; membrane properties; neuronal channel functions; EEG and brain waves generation; oscillatory mechanisms; thalamo-cortical rhythms, different EEG waves; general organization of the spinal cord and spinal reflexes; brainstem reflexes; function of the superior colliculus; coding of sensory information; physiological basis of perception; general organization of the cerebral cortex; primary and associative areas; function and organization of motor systems.

Lectures and integrative teaching seminars.
Any change to the methods described, will be communicated on the web sites of the Department and of the Study Program or provided by the faculty at the beginning of the course.
The exam will include a written assessment, which may consist of multiple-choice (true or false) questions or open-ended written questions with concise answers. To successfully pass the exam, students are required to demonstrate a satisfactory comprehension of all the topics covered in the course.
This course explores topics closely related to two goals of the United Nations 2030 Agenda for Sustainable Development (SDGs). Specifically,
N.3 Health and wellbeing
N.4 Education of quality
