Yves von Cramon Director Functional Neuroanatomy of the 1 Frontal Lobe Department of Cognitive Neurology Studying the cognitive functions of the frontal lobe is a challenging under- taking. The work group “Functional Neuroanatomy of the Frontal Lobe” en- gages in this venture, aiming at a functional exploration of the various facets of this brain region in both healthy subjects and neurological patients. The underlying motivation guiding the group’s endeavours is to integrate indi- vidual findings into a unified functional framework. Of the two projects that have investigated social interaction, one aimed to decompose the neuronal network underlying higher order intentionality (1.1.1), while the other focused on intertemporal decision making for oneself as compared to others (1.1.2). In contrast to many laboratory implementations of decision making, daily life often requires intuitive decisions, which draw particularly on orbitofrontal structures (1.1.3), and choices which are only par- tially determined by ourselves (1.1.4). However, before deciding what to do, we first have to decide whether to engage in an action or to refrain from it (1.1.5). While the dorsal frontomedian cortex plays a role in the intentional inhibition of action, transcranial magnetic stimulation (TMS) over the inferior frontal junction area induced disturbances in task set formation during a task switching paradigm (1.1.6). However, even when we know what we want to do, we often make errors due to time constraints. Awareness of making errors was found to modulate insular activity reflecting autonomic reactions, whereas posterior frontomedi- an regions remained unmodulated (1.1.7). Interestingly, individual differences in such performance monitoring can be related to a genetic polymorphism associated with variable dopamine receptor density. Indeed, genetic differ- ences were found to have a significant impact on the ability to learn from errors (1.1.8). The vital role of becoming aware of our own errors is to trigger adaptive behavior. The same applies for unexpected events which we ob- serve but do not initiate ourselves. Indeed, the neural correlates of expec- tancy violation were found to be heavily dependent on the specific nature of Functional Neuroanatomy of the Frontal Lobe expectations (1.1.9). Such findings indicate a critical role its relation to neurovascular coupling impairments using played by the premotor system in rule-based predictive functional near-infrared spectroscopy in patients suffer- contexts, which is in line with a new framework that pro- ing from cerebral microangiopathy (1.2.2).
