- Clinical Project with Laboratory work
What is the background of the project?
DESCRIPTION: The Sleep and Wake Cycle is one of the key events in human life. The reduction in the duration of sleep or your irregularity, caused by many reasons based on pathologic states or the contemporary habits of life, results in a metabolic and behavioral dysfunction. In this last aspect, we highlight the memory, performance and changes in affective state. AIM: The main objective of the project is to investigate the neural mechanisms responsible for regulation of sleep and wake cycle, through electrophysiological techniques. In addition, assess the consequences of your disruption on human health through behavioral studies. USED TECHNIQUES: This study includes human Electrophysiology, Polysomnography, Actimetria and Psychophysics.
What is the aim of the project?
The main objective of the project is to investigate the neural mechanisms responsible for regulation of sleep and wake cycle, through electrophysiological techniques. In addition, assess the consequences of your disruption on human health through behavioral studies.

This study includes human Electrophysiology, Polysomnography, Actimetria and Psychophysics.
What is the role of the student?
- The student will mainly observe
- The student will observe the practical experiments but will be highly involved in the analysis of the results
What are the tasks expected to be accomplished by the student?
The student will mainly observe and will be supervised until he/she learn how to do the procedures needed, specifically, electrophysiological studies, in particular, polysomnography, in which the student will be involved in all procedures, such as placement of electrodes and sensors; use of biopotentials record software; analysis of electrophysiological data, in particular those related to the stage of sleep. In addition, use of actimetry and analysis of the data collected through computational routines of activity data and applications of behavioral test for evaluation of memory, emotion and cognition.
Will there be any theoretical teaching provided (preliminary readings, lectures, courses, seminars etc)
During the Exchange, the student will participate in scientific meetings, in which will have presentations and discussions of articles about sleep medicine and Neurobiology in general.
What is expected from the student at the end of the research exchange? What will be the general outcome of the student?
- The student will prepare a poster
What skills are required of the student? Is there any special knowledge or a certain level of studies needed?
To have studied Neurophysiology at the university.
Are there any legal limitations in the student’s involvement
No
