A method for automatic estimation of fractional anisotropy along of cerebral tracts related with the emergency of consciousness

Mai 23, 2022

ABSTRACT The emergency of consciousness continue to be open challenge the scientific community. Tools such as diffusion weighted imaging (DWI) and tractography try to settle this debate by showing the processes at the biological level of the a conscious states. Even though many studies have explored structural features in different mental states, the reference values of the brain structures that underlie the emergence of consciousness in healthy subjects are still unknown. Then, this work aims to identify reference values for fractional anisotropy as a structural integrity measurement among white matter pathways involved in emergency of consciousness within a group of 100 healthy subjects from Human Connectome Project. Results showed based on statistical analysis that exists reference values of fraction of anisotropy in healthy subject for the corticothalamic pathway.
