Functional and Anatomical Cortical Underconnectivity in Autism
Underconnectivity in autistics was found during challenge, by reduced
synchronization between frontal and parietal areas of activation and
smaller sections of the corpus callosum.
www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=16772313

Disordered connectivity in the autistic brain
Autism appears to consists of an abnormality of information
integration that is caused by a reduction in the connectivity between
specialized areas of the brain.
www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=16820239

Partially enhanced thalamocortical functional connectivity in autism.
Authors argue against general underconnectivity in autism and instead
suggest hyperfunctional subcortico-cortical connectivity, which may
compensate for reduced cortico-cortical connectivity.
www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=16828063

Simultaneous EEG and fMRI applied to epilepsy.
Integrating of both electrophysiologic and metabolic information
provides much insight into cerebral physiology.

Provides rationale and practice for using sensorimotor rhythm
conditioning to reduce susceptibility of seizures.

Self-Regulation of Slow Cortical Potentials in Seizure Patients.
Decreased seizure frequency from this form of neurofeedback training
may be due to inhibition in cortical areas proximal to active
electrodes, frontal cortex, and thalamus.
www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=16691432

Fronto-parietal coupling of brain rhythms in mild cognitive impairment
Elderly with Alzheimer's present a reduction of synchronization
likelihood (delta to gamma) at both fronto-parietal and
inter-hemispherical electrodes whereas normal functioning elderly do not.

EEG coherence in mild cognitive impairment
EEG coherences in all bands were higher in a mild cognitive
impairment group compared to controls during effort, but similar

Impaired functional connectivity at alpha and theta bands in major
depression.
Right anterior and left posterior brain areas may discriminate
depressive patients from controls in terms of connectivity.

Frontal EEG Asymmetry, Emotional Intelligence, and Externalizing Behaviors
Emotional intelligence and frontal EEG asymmetry at rest are
independent predictors of child externalizing behaviors.
