Pulvermuller goes on to state, “Semantic processing may occur in an integration center or ‘semantic hub’ that joins together the various aspects of a word’s meaning, for example, in the case of the word ‘fish’, about shape, color, smell and taste. Although a specialized area is in fact not necessary for integration of semantic information - because the binding of multimodal semantic features into one coherent representation may rely on long-range cortico-cortical connections - it is possible that such a single hub exists. However, neuroimaging and neuropsychological studies have revealed several cortical regions that may support general meaning processes.”
The author rightly questions how sensorimotor input is correlated into coherent semantic information, such as “fish” with its shape, color, smell and taste properties. Indeed, there are long-range cortico-cortical connections that transmit encoded information within synchronous, coherent wave frequencies, shapes and amplitudes. This topic has been addressed in my blogs. But what gives neural wave forms meaning - semantics - as well as purpose? The wave forms themselves? I submit that the immaterial mind has the created capacity to interpret the linguistic neural codes and thereby to understand their meaning - semantics - and purpose as well as to give action to the codes. I submit that the mind is the integrating center, the “semantic hub.” Pulvermuller stated above that, “Although a specialized area is in fact not necessary for integration of semantic information - because the binding of multimodal semantic features into one coherent representation may rely on long-range cortico-cortical connections - it is possible that such a single hub exists.”
