Early effects of semantic meaning on electrical brain activity

Journal/Book: Behav Brain Sci. 1999; 22: 40 West 20Th Street, New York, NY 10011-4211, USA. Cambridge Univ Press. 301+.

Abstract: When words are read, the visual cortex is activated, independent of whether visual or motor associations are elicited. Tills word-evoked brain activity is significantly influenced by semantic meaning. Such effects occur very early after stimulus presentation (at latencies between 80 and 130 msec), indicating that semantic meaning activates different neuronal assemblies in the human visual cortex when words are processed.
