Epilepsy arises from network dysfunction, not single sources. Noninvasive neuroimaging like functional MRI (fMRI) and EEG/MEG reveal functional connectivity, aiding epilepsy diagnosis and surgical outcome prediction.
Area of Science:
- Neurology
- Neuroimaging
- Systems Neuroscience
Background:
- Epilepsy is a common chronic neurological disorder.
- Evidence suggests epilepsy results from epileptic network dysfunction rather than isolated pathological activity.
Purpose of the Study:
- To review recent advances in understanding functional connectivity in epilepsy using noninvasive neuroimaging techniques.
Main Methods:
- Functional MRI (fMRI) for hemodynamic analysis.
- Electroencephalography (EEG) and Magnetoencephalography (MEG) for electro-magnetic analysis.
Main Results:
- Functional connectivity analysis using fMRI and EEG/MEG provides insights into the physiopathogenesis of epileptic networks in focal epilepsies and syndromes.
- These techniques aid in localizing epileptic foci and predicting postsurgical cognitive impairment by analyzing interactions between pathological and physiological networks.
Conclusions:
- fMRI and EEG/MEG functional connectivity are complementary tools for identifying interactions between epileptic activity and physiological networks at various scales.
- These interactions can explain neuropsychological and neuropsychiatric impairments.
- Functional connectivity analysis helps localize epilepsy drivers and predict postsurgical outcomes, necessitating strict validation of methods.

Overview of Advanced Functional Groups
Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.

Higher Mental Functions of the Brain: Language
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
