EEG Correlates of Mild Impairments of Higher Cortical Functions

Human Physiology Aims and scope Submit manuscript

Abstract

Correlations between the impairments of higher cortical functions (assessed by clinical scores and neuropsychological tests) and multichannel EEG spectra were analyzed in elderly patients with mild dementia and children with cognitive problems. A decrease in the regional cerebral blood flow, an imbalance between neocortical and limbic structures, and a lack of inhibitory influences from the frontal cortex are discussed as probable causes of these brain functional disorders associated with a “slow sensorimotor rhythm.”
