This project thesis aims to explore the impact of sleep deprivation on brain connectivity using functional Magnetic Resonance Imaging (fMRI). By analyzing brain activity patterns during periods of sleep deprivation, researchers can better understand the alterations in neural networks and how they influence cognitive functions, mood, and overall health. The findings from this study can provide valuable insights into the consequences of sleep deprivation on brain functioning.

Project Overview
Title: Investigating the Effects of Sleep Deprivation on Brain Connectivity Using Functional Magnetic Resonance Imaging
Sleep is a crucial component of human health and well-being, playing a vital role in various cognitive functions and processes. Sleep deprivation is a common issue in modern society, with many individuals not getting an adequate amount of sleep on a regular basis. The impact of sleep deprivation on cognitive function and brain connectivity has been the subject of extensive research in recent years.
This project aims to investigate the effects of sleep deprivation on brain connectivity using functional magnetic resonance imaging (fMRI). fMRI is a powerful imaging technique that allows researchers to study brain activity by measuring changes in blood flow. By analyzing fMRI data, researchers can map out the functional connections between different regions of the brain and understand how these connections are disrupted by sleep deprivation.
The project will involve recruiting a group of participants and dividing them into two groups – one that will undergo a period of sleep deprivation and one that will be allowed to sleep normally. The participants will then undergo fMRI scans before and after the sleep manipulation to assess any changes in brain connectivity. Data analysis will involve comparing the connectivity patterns between the two groups and identifying any differences that may be attributed to sleep deprivation.
The potential outcomes of this research project include a better understanding of how sleep deprivation affects brain connectivity, which could have implications for various cognitive functions such as memory, attention, and decision-making. The findings from this study could also provide insights into the development of interventions or treatments to mitigate the negative effects of sleep deprivation on the brain.
In conclusion, investigating the effects of sleep deprivation on brain connectivity using fMRI is a significant research endeavor that has the potential to advance our understanding of the impact of sleep on cognitive function and brain health. By utilizing advanced imaging techniques and rigorous data analysis, this project aims to contribute valuable insights to the field of sleep research and neuroscience.
