The Iowa Gambling Task (IGT) is a sensitive test for the detection of decision-making impairments in several neurological and psychiatric populations. Very few studies have employed the IGT in functional magnetic resonance imaging (fMRI) investigations, in part, because the task is cognitively complex. Here we report a method for exploring brain activity using fMRI during performance of the IGT. Decision-making during the IGT was associated with activity in several brain regions in a group of healthy individuals. The activated regions were consistent with the neural circuitry hypothesized to underlie somatic marker activation and decision-making. Specifically, a neural circuitry involving the dorsolateral prefrontal cortex (for working memory), the insula and posterior cingulate cortex (for representations of emotional states), the mesial orbitofrontal and ventromedial prefrontal cortex (for coupling the two previous processes), the ventral striatum and anterior cingulate/SMA (supplementary motor area) for implementing behavioral decisions was engaged. These results have implications for using the IGT to study abnormal mechanisms of decision making in a variety of clinical populations. Hum Brain Mapp, 2009. (c) 2009 Wiley-Liss, Inc. [less ▲]

Recent functional neuroimaging studies have shown that reflecting on representations of the present self versus temporally distant selves is associated with higher activity in the medial prefrontal cortex (MPFC). In the current fMRI study, we investigated whether this effect of temporal perspective is symmetrical between the past and future. The main results revealed that the MPFC showed higher activity when reflecting on the present self than when reflecting on past and future selves, with no difference between past and future selves. Temporal perspective also modulated activity in the right inferior parietal cortex but in the opposite direction, activity in this brain region being higher when reflecting on past and future selves relative to the present self (with again no difference between past and future selves). These findings show that differences in brain activity when thinking about current versus temporally distant selves are symmetrical between the past and the future. It is suggested that by processing degrees of self-relatedness, the MPFC might sustain the process of identifying oneself with current representations of the self, whereas the right inferior parietal cortex might be involved in distinguishing the present self from temporally distant selves.

This study examined narrative identity in a group of 81 patients with schizophrenia and 50 healthy controls through the recall of self-defining memories. The results indicated that patients' narratives were less coherent and elaborate than those of controls. Schizophrenia patients were severely impaired in the ability to make connections with the self and extract meaning from their memories, which significantly correlated with illness duration. In agreement with earlier research, patients exhibited an early reminiscence bump. Moreover, the period of the reminiscence bump, which is highly relevant for identity development, was characterized by fewer achievements and more life-threatening event experiences, compared with controls. A negative correlation was found between negative symptoms, number of self-event connections and specificity of narratives. Our results suggest that schizophrenia patients have difficulties to organize and extract meaning from their past experiences in order to create coherent personal narratives. [less ▲]

Several individual differences affecting four dimensions of self-defining memories (SDMs)--structure, content, affect, and autobiographical reasoning (Blagov & Singer, 2004; McLean & Fournier, 2008; Singer & Salovey, 1993)--have been observed in young adults (principally in North America). In this study we aimed to investigate the relationships between the different dimensions of SDMs, providing further evidence of the content validity of the Self-Defining Memory task. It was possible to discern two specific profiles from the three SDMs collected from each participant. Almost half the participants retrieved specific SDMs with little autobiographical reasoning and tension; the other participants retrieved an opposite profile, suggesting that there are individual differences in the cognitive and affective processes related to the construction of SDMs. The second aim of the study was to conduct across-cultural extension of research on SDMs, using a sample of Swiss young adults. The results were similar to those obtained by previous studies, suggesting a certain cultural invariability. The only difference observed concerned the number of SDMs containing meaning making. Swiss young adults attribute more explicit meanings to their memories than North American young adults, suggesting that they are more engaged in autobiographical reasoning. [less ▲]

Abstract Episodic future thinking allows humans to mentally simulate virtually infinite future possibilities, yet this device is fundamentally goal-directed and should not be equated with fantasizing or wishful thinking. The purpose of this functional magnetic resonance imaging study was to investigate the neural basis of such goal-directed processing during future-event simulation. Participants were scanned while they imagined future events that were related to their personal goals (personal future events) and future events that were plausible but unrelated to their personal goals (nonpersonal future events). Results showed that imaging personal future events elicited stronger activation in ventral medial prefrontal cortex (MPFC) and posterior cingulate cortex (PCC) compared to imaging nonpersonal future events. Moreover, these brain activations overlapped with activations elicited by a second task that assessed semantic self-knowledge (i.e., making judgments on one's own personality traits), suggesting that ventral MPFC and PCC mediate self-referential processing across different functional domains. It is suggested that these brain regions may support a collection of processes that evaluate, code, and contextualize the relevance of mental representations with regard to personal goals. The implications of these findings for the understanding of the function instantiated by the default network of the brain are also discussed. [less ▲]

Personality changes are frequently described by caregivers of patients with Alzheimer's disease, while they are less often reported by the patients. This relative anosognosia of Alzheimer disease (AD) patients for personality changes might be related to impaired self-judgment and to decreased ability to understand their caregiver's perspective. To investigate this issue, we explored the cerebral correlates of self-assessment and perspective taking in patients with mild AD, elderly and young volunteers. All subjects assessed relevance of personality traits adjectives for self and a relative, taking either their own or their relative's perspective, during a functional imaging experiment. The comparison of subject's and relative's answers provided congruency scores used to assess self-judgment and perspective taking performance. The self-judgment "accuracy" score was diminished in AD, and when patients assessed adjectives for self-relevance, they predominantly activated bilateral intraparietal sulci (IPS). Previous studies associated IPS activation with familiarity judgment, which AD patients would use more than recollection when retrieving information to assess self-personality. When taking a third-person perspective, patients activated prefrontal regions (similarly to young volunteers), while elderly controls recruited visual associative areas (also activated by young volunteers). This suggests that mild AD patients relied more on reasoning processes than on visual imagery of autobiographical memories to take their relative's perspective. This strategy may help AD patients to cope with episodic memory impairment even if it does not prevent them from making some mind-reading errors. [less ▲]

Previous studies have shown that patients with schizophrenia are impaired in recalling specific events from their personal past. However, the relationship between autobiographical memory impairments and disturbance of the sense of identity in schizophrenia has not been investigated in detail. In this study the authors investigated schizophrenic patients' ability to recall self-defining memories; that is, memories that play an important role in building and maintaining the self-concept. Results showed that patients recalled as many specific self-defining memories as healthy participants. However, patients with schizophrenia exhibited an abnormal reminiscence bump and reported different types of thematic content (i.e., they recalled less memories about past achievements and more memories regarding hospitalisation and stigmatisation of illness). Furthermore, the findings suggest that impairments in extracting meaning from personal memories could represent a core disturbance of autobiographical memory in patients with schizophrenia. [less ▲]

Nous avons récemment observé que le cortex préfrontal ventro-médial (CPFVM) est activé à la fois chez des sujets jeunes et âgés dans une tâche de jugement d’adjectifs nécessitant d’évaluer sa propre personnalité par rapport à celle d’un autre dans le contexte d’un prise de perspective à la première (1PP) et à la troisième (3PP) personne (Ruby et al., submitted). Nous avons poursuivi l’analyse de ces données par des analyses de connectivité fonctionnelle afin de déterminer le réseau des régions cérébrales associées à la performance des sujets jeunes et âgés. Les résultats montrent qu’en 1PP, l’activité du CPFVM est associée à celle du gyrus frontal inférieur et du gyrus parahippocampique chez les sujet âgés, mais uniquement à celle du cortex occipital chez les sujets jeunes. En 3PP, une connectivité fonctionnelle existe entre le CPFVM et le gyrus frontal médial, le gyrus frontal inférieur et les régions temporales supérieures chez les sujets âgées ; mais uniquement avec les régions occipitale et pariétale chez les sujets jeunes. Les régions cérébrales associées à l’activité du CPFVM chez les sujets jeunes ont été décrites comme impliquées dans la récupération en mémoire autobiographique ainsi que dans les processus de « mentalizing ». En ce qui concerne les personne âgées, le réseau cérébral découvert est relié à la récupération de souvenirs sémantique et épisodique (gyrus parahippocampique et temporal supérieur) mais aussi à l’attribution d’une valence émotionnelle à l’adjectif (gyrus frontal inférieur) et à la prise de perspective (gyrus frontal médial). Ces résultats indiquent (1) que le CPFVM est connecté à un réseau cérébral plus important chez les personnes âgées que chez les jeunes lors de jugement sur soi ; (2) que les sujets jeunes réalisent la tâche sur base d’informations autobiographiques seulement alors que les personnes âgées recrutent en plus des processus cognitifs de nature plus réflexive.

Being able to envision emotional events that might happen in the future has a clear adaptive value. This study addressed the functional neuroanatomy of this process and investigated whether it is modulated by temporal distance. Participants imagined positive and negative events pertaining to the near future or far future while their brain activity was measured with fMRI. The results demonstrate that the anterior part of the ventromedial prefrontal cortex (vmPFC) was more active in envisioning emotional events in the far future than in the near future, whereas the caudate nucleus was engaged in envisioning emotional (especially positive) situations in the near future. We argue that the anterior part of the vmPFC might assign emotional values to mental representations of future events that pertain to long-term goals. On the other hand, the caudate might support more concrete simulations of action plans to achieve rewarding situations in the near future. [less ▲]

It has been suggested that patients with schizophrenia experience a distorted sense of continuity of self across time. However, temporal aspects of self-processing have received little empirical attention in schizophrenia. In this study, the authors investigated schizophrenic patients' ability to generate specific mental images of their personal past and future. Results showed that patients recalled fewer specific past events than did healthy controls and were even more impaired in generating specific future events. These deficits were associated with positive symptoms but were not associated with negative symptoms or with performances on verbal fluency tasks. It is suggested that schizophrenic patients' failures to project themselves into specific past and future episodes might be related to difficulties in retrieving contextual details from memory, as well as disturbance of the sense of subjective time.

Precise brain regions are activated when a subject gives a judgment on himself. Those are the medial parietal cortex, essentially related to episodic memory processing, and the ventromedial prefrontal cortex, recruited for evaluating the personal valence of an information. These regions are not activated in Alzheimer's disease. The decrease of awareness for own deficits in a patient with Alzheimer's disease would depend on a reduction of episodic memory capacities and a worsening of judgment for self significance. [less ▲]
