How does the cortex create thought, concept and meaning?
1. D.O. Hebb: Cell Assembly -Complex assembly of neurons responsible for representing objects or ideas. Example: Face 2. D.O. Hebb: Phase Sequences -Different cell assemblies become organized into phase sequences. -The phase sequence represents the common activation different cell assemblies. Example: A babys environment 3. Cell Assemblies and Phase Sequences collectively form Neural Networks. III. Cerebral Asymmetry A. Anatomical Asymmetry in the cortex: -Primary auditory cortex is larger in right hemisphere. -Temporal lobe is larger in the right hemisphere. B. Functional Asymmetry in the cortex: -Language is produced by the left hemisphere (over 90% of individuals). -Comprehension and production of American Sign Language (ASL) is controlled by the left hemisphere. -Sight reading (music) is controlled by the left hemisphere. 1.
