Empirical Network Model of Human Higher Cognitive Brain Functions

摘要

EEG Systems Laboratory (EEGSL) develops and applies advanced technologies formeasuring neurocognitive signals in the human brain. Results during the period 1APR87 to 31MAR90 included: (1) measurement o leading indicator neuroelectric patterns preceding performance decrements in five Air Force fighter test pilots who performed difficult cognitive tasks for 10-14 hours; (2) measurement of split-second neurocognitive patterns of basic linguistic operations which distinguished letter from non-letter, word from non-word, and syntactic from non-syntactic processing; and (3) functional anatomical localization based on 124-channel evoked potential recordings and three dimensional finite-element brain models constructed from magnetic resonance images.
