Functional Segregation of Broca’s Area in Sentence Comprehension
|
generic
|
A functional segregation takes place inside the left prefrontal cortex, including Broca's area proper in two information processing gradients. Superior and posterior regions, including BA 6/9/46/44, would be preferentially engaged in sequential and structural aspects of sentence comprehension, with more shallow parses or canonical structures processed in upper parts of this network, whereas deeper, more complex or working-memory demanding parses would involve more inferior regions. Anterior and inferior regions, including BA 11/47/45, would be implicated in content information insertion into structural matrices selected in upper regions.

Separation of dorsal and ventral visual streams
|
generic
|
The dorsal visual path extends into the parietal cortex and represents information crucial for object interaction while the ventral stream extends into the inferotemporal cortex and recognizes the identity of an object (Ungerleider & Mishkin, 1982; Goodale & Milner, 1992; Castiello & Jeannerod, 1991)
