====== Frontal lobe connections ======
Catani et al. identified three intralobar tracts connecting: i) posterior [[Broca's area]] with [[supplementary motor area]] (SMA) and pre-supplementary motor area (pre-SMA) (i.e., the [[frontal aslant tract]] - FAT); ii) posterior orbitofrontal cortex with anterior polar region (i.e., [[frontoorbitopolar tract]] - FOP); iii) posterior [[precentral cortex]] with anterior prefrontal cortex (i.e., the frontal superior longitudinal - FSL faciculus system). In addition more complex systems of short U-shaped fibres were identified in the regions of the central, pre-central, perinsular and fronto-marginal sulcus (FMS). The connections between Broca and medial frontal areas (i.e. FAT) and those between the hand-knob motor region and post-central gyrus (PoCG) were found left lateralized in a group of twelve healthy right-handed subjects. The existence of these short frontal connections was confirmed using post-mortem blunt dissections. The functional role of these tracts in motor learning, verbal fluency, prospective behaviour, episodic and working memory is discussed in the study of Catani et al. provides a general model for the local connectivity of the [[frontal lobe]]s that could be used as an anatomical framework for studies on lateralization and future clinical research in neurological and psychiatric disorders
