**3. Dorsolateral prefrontal loop**

The dorsolateral prefrontal loop is responsible for the choice of aims, planning, programming of the sequence of mental actions and behaviours, switching between sentences (the ability to change attitude flexibly), verbal and spatial working memory, selfcontrol and metacognition (self-consciousness) (Royall et all., 2002). The disorders of the loop functions can lead to incorrect order of linguistic behaviours what results in verbal fluency reduction (DeLong & Wichmann, 2007).
