“…The processing of happy expressions has been related to activation of the anterior and posterior cingulated gyrus, medial frontal cortex, and orbitofrontal cortex [ 61 , 62 ]. Evidence from patients with Huntington's disease shows that damage to the basal ganglia impairs the recognition of both negative and positive emotional signals [ 18 ].…”

Because of dopaminergic neurodegeneration, patients with Parkinson's disease (PD) show impairment in the recognition of negative facial expressions. In the present study, we aimed to determine whether PD patients with more advanced motor problems would show a much greater deficit in recognition of emotional facial expressions than a control group and whether impairment of emotion recognition would extend to positive emotions. Twenty-nine PD patients and 29 age-matched healthy controls were recruited. Participants were asked to discriminate emotions in Experiment 1 and identify gender in Experiment 2. In Experiment 1, PD patients demonstrated a recognition deficit for negative (sadness and anger) and positive faces. Further analysis showed that only PD patients with high motor dysfunction performed poorly in recognition of happy faces. In Experiment 2, PD patients showed an intact ability for gender identification, and the results eliminated possible abilities in the functions measured in Experiment 2 as alternative explanations for the results of Experiment 1. We concluded that patients' ability to recognize emotions deteriorated as the disease progressed. Recognition of negative emotions was impaired first, and then the impairment extended to positive emotions.

“…Emotion has been associated with PCC and a review concludes that "the retrosplenial cortex is the cortical region that is most consistently activated by the emotional salience of experimental stimuli" (Maddock, 1999), where "retrosplenial" here means the most-caudal part of PCC (Vogt et al, 2000;Vogt et al, 2001). Apart from articles mentioned by the review (Maddock, 1999) PCC has been associated with emotion in, e.g., facial anger viewing (Sprengelmeyer et al, 1998), facial happiness viewing (Phillips et al, 1998;Kilts et al, 1996), visual elicited phobic fear (Fredrikson et al, 1995) and romantic love (Bartels and Zeki, 2000). A single component contains a number of these emotion studies, but the component is not very "clean" in the sense that it does not exclusively contain emotion studies, so we can only leniently conclude that there is a tendency for overlap between the emotion and the memory in the spatial distribution in Talairach space and it appears in caudal PCC.…”

Mining the posterior cingulate: Segregation between memory and pain components

2005

We present a general method for automatic meta-analyses in neuroscience and apply it on text data from published functional imaging studies to extract main functions associated with a brain area-the posterior cingulate cortex (PCC). Abstracts from PubMed are downloaded, words extracted and converted to a bag-of-words matrix representation. The combined data are analyzed with hierarchical non-negative matrix factorization. We find that the prominent themes in the PCC corpus are episodic memory retrieval and pain. We further characterize the distribution in PCC of the Talairach coordinates available in some of the articles. This shows a tendency to functional segregation between memory and pain components where memory activations are predominantly in the caudal part and pain in the rostral part of PCC.

“…The application of this stimulus condition is generally aimed at describing the ability to discriminate between affective categories [30–35]. Recent investigations have demonstrated that recognition of facial affect, particularly fearful affect, induces demonstrable changes in brain activation [36–39]. Furthermore, neuroimaging studies of affective reactivity have reported altered lateral prefrontal activation in addition to changes in medial prefrontal activation [40–43].…”
