The dorsal anterior cingulate cortex (dACC) has been implicated in a broad range of cognitive and emotional functions, including the processing of negative emotion. Furthermore, abnormalities in dACC activity have been associated with anxiety and depression, disorders in which negative emotion is dysregulated. Thus, a better understanding of the precise contributions of the dACC to negative emotion could give us important insights into the neurobiological mechanisms underlying these debilitating neuropsychiatric disorders. However, despite extensive study of the dACC, its precise role in negative emotion is unclear. Instead there is mounting evidence that rather than being one functionally homogeneous region, subregions of the dACC may have distinct functional roles. This evidence is largely correlational, and interventional studies in experimental animals are required to address this. Accordingly, the work in this thesis causally assessed the contributions of two spatially distinct subregions of the dACC (rostral and caudal) to the regulation of the behavioural and cardiovascular correlates of negative emotion in the common marmoset (Callithrix jacchus). These dACC subregions were targeted with indwelling cannulae to enable pharmacological manipulations to be carried out in a range of tasks, used to assess distinct components of negative emotion, such as conditioned fear and anxiety. The findings suggest that the rostral dACC and the caudal dACC do indeed have distinct contributions to the expression of negative emotion and the regulation of anxiety, respectively. Furthermore, an assessment of the anterograde projections of these subregions provides anatomical support for the observed functional differences.

Background: The learning perspective of panic disorder distinguishes between acute panic and anxious apprehension as distinct emotional states. Following animal models, these clinical entities reflect different stages of defensive reactivity depending upon the imminence of interoceptive or exteroceptive threat cues. The current study tested this model by investigating the dynamics of defensive reactivity in a large group of patients with panic disorder and agoraphobia (PD/AG). Methods: Three hundred forty-five PD/AG patients participated in a standardized behavioral avoidance test (being entrapped in a small, dark chamber for 10 minutes). Defense reactivity was assessed measuring avoidance and escape behavior, self-reports of anxiety and panic symptoms, autonomic arousal (heart rate and skin conductance), and potentiation of the startle reflex before and during exposure of the behavioral avoidance test. Results: Panic disorder and agoraphobia patients differed substantially in their defensive reactivity. While 31.6% of the patients showed strong anxious apprehension during this task (as indexed by increased reports of anxiety, elevated physiological arousal, and startle potentiation), 20.9% of the patients escaped from the test chamber. Active escape was initiated at the peak of the autonomic surge accompanied by an inhibition of the startle response as predicted by the animal model. These physiological responses resembled the pattern observed during the 34 reported panic attacks. Conclusions: We found evidence that defensive reactivity in PD/AG patients is dynamically organized ranging from anxious apprehension to panic with increasing proximity of interoceptive threat. These data support the learning perspective of panic disorder.
