Functional Connectivity and Genetic Profile of a "Double-Cortex"-Like Malformation
2018
Frontiers in Integrative Neuroscience
Preserved Fulltext
We conducted an original functional MRI (fMRI) analysis in a drug-resistant epilepsy patient with "doublecortex"-like malformation to reveal her functional connectivity (FC) as well as a wide genetic analysis ...
This first FC analysis of a unique case of "double-cortex"-like malformation revealed a hemispheric connectivity segregation both in the laminar cortex as in the correctly migrated one, with a new pattern ...
Interestingly, the pattern of co-activation during the task also reflected connectivity measured during resting-state. ...
