Electrophysiological Correlates of Meaning

The use of context-sensitive symbols offers an appropriate methodology for investigating the representation of meaning in the brain. This approach revealed that late components of frontal, but not occipital, evoked potentials reflect the change of meaning of a symbolic stimulus when it appears in di...

Description
Summary:The use of context-sensitive symbols offers an appropriate methodology for investigating the representation of meaning in the brain. This approach revealed that late components of frontal, but not occipital, evoked potentials reflect the change of meaning of a symbolic stimulus when it appears in different temporal contexts.
