Applying engineering to neuroscience, the silver thread of the course will be the analysis of the human brain at different level of integration: from the single cell to small neural networks up to organ level, quantitatively measuring brain metabolism and studying complex brain functions such as neural control of muscle synergies, visual-sensory integration, and dual tasking.

The student will acquire the knowledge of currently available and emerging technologies for interfacing with the human brain. The student will obtain the ability to acquire real brain signals and process these signals using Matlab algorithms. Soft skills will also be developed such as: the ability to work in a team to deal with a laboratory assignment mimicking a real-world problem; the competence to analyze information in the literature and apply that information to a novel problem; and the capability to communicate effectively the methodological choices adopted to solve a problem.

Frontal lessons (39 h) + 4 Labs (21 h). During the Labs the students will work in teams of 4 persons. The frequency to the labs is mandatory to take the final examination.

Slides, articles and laboratory assignments provided by the teacher. Data and signals acquired during lab sessions + Matlab code to get some practice on how to process signals and analyze/interpret data.

Modalità di esame: Elaborato scritto prodotto in gruppo; Prova scritta in aula tramite PC con l'utilizzo della piattaforma di ateneo;

Exam: Group essay; Computer-based written test in class using POLITO platform;

... The exam is aimed to verify the acquisition of the knowledge and skills described in the Expected Learning Outcomes. It will be composed of 2 parts: - WRITTEN TEST with structured (multiple choice, true/false), semi-structured (exercises, table completion,...) and open-ended questions about the topics covered during the frontal lessons and the Labs. The written test lasts 1 hour. During the exam it is not allowed to keep notes, or other Course materials, while it is allowed to use a calculator. (Language: English). - LABORATORY REPORTS. After each Lab, the Lab-team of 4 students will produce a Powerpoint presentation with a textual and/or graphical description of the methods used to solve the Lab assignments, the results obtained, and the discussion of the results obtained. Feedback and scores about the Lab reports will be provided during the Course.(Language: English). The final mark, expressed in thirtieths, will be obtained as the sum of the two following scores: - WRITTEN TEST: up to 23/33 points (minimum acceptable score to pass: 10) - LABORATORY REPORTS: up to 10/33 points. If the final mark is equal to or greater than 31.5 the Laude will be assigned. The exam scores will be communicated on the didactic web portal, as well as the date in which the students will be able to view the written test and ask for explanations.

Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.
