Influence of sleep deprivation on Executive function , Simon task and Choice reaction times among shift workers: A Comparative Study
India (MSAI) - Jawaharlal Nehru Medical College/KLE University, Belagavi
Dr. Nirmala S. Anand
Type of Research Project
- Clinical Project with Laboratory work
What is the background of the project?
Adults require an average 7-8 hours of sleep, sleep of shorter duration than that causes sleep deprivation(SD) and is associated with deterioration of neurobehavioral performance. Total sleep deprivation (TSD) negatively affects many physiological, cognitive, and behavioral measures within the body such as impaired perception, difficulties in concentration, vision disturbances and slower reactions. Sleep deprivation is a part of people working in shifts. Shift workers have an altered circadian cycle and dyshomeostasis. This affects physiological as well as psychomotor functions and has been confirmed by many studies. Sleep deprivation also leads to altered cognitive processing and execution. MRI identified the frontal and pre frontal cortex of the brain which are involved in executive functions and is highly susceptible to sleep loss. Many studies IFMSA International Secretariat, c/o IMCC, Nørre Allé 14, 2200 København N., Denmark have proven that adequate sleep or power naps alleviate the bad side effects of sleep deprivation. There are very few studies addressing executive functioning and reaction times in response to sleep deprivation. This encourages us to intrigue the topic and study in depth about it.
What is the aim of the project?
The aim of this study is to assess the effect of one night sleep deprivation on daytime executive function and Reaction time of subjects the following day.
What techniques and methods are used?
What is the role of the student?
- The tasks will be done under supervision
What are the tasks expected to be accomplished by the student?
Sleep deprivation hits at least 1 among 10 people across the world and shift workers bear the brunt of this in the form of altered homeostasis which is the lead cause of most diseases. The focus of this study domains itself into bio circadian rhythm physiology. The organ most affected by sleep deprivation is the nervous system which is responsible for cognitive abilities as well as execution. So the outcome of conducting such research is that we can solve the nexus involved in sleep deprivation, shift work and cognitive functioning At the end of the exchange programme the student shall be in a position to conduct researches which involve conducting psychometric tests on individuals, collecting the data, interpreting the results , understanding the study design and application of the results so the final outcome of this exchange would be that the student shall get a taste of the cultural context and research acumen.
Will there be any theoretical teaching provided (preliminary readings, lectures, courses, seminars etc)
Yes, If tutor deems necessary
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 - The student will prepare a presentation
What skills are required of the student? Is there any special knowledge or a certain level of studies needed?
No specific skills required
Are there any legal limitations in the student’s involvement
