Levels of Integration in Cognitive Control and Sequence Processing in the Prefrontal Cortex

Figure 1

Description of experimental design.

A: The square indicated to process the syllable sequences according to the artificial grammar (AG) rule (contextual-cue and grammar-task). Next, the upwards triangle indicated to repeat the AG task (episodic-cue and grammar-task). The diamond determined to apply the counting rule (contextual-cue and counting-task). Finally, the downwards triangle indicated to switch to the AG rule (episodic-cue and grammar-task). Syllables were presented each-by-each. B: Count-task: count /e/ syllables and match with /o/ syllables. Grammar-task: center-embedded processing of category A and category B syllables.
