  abstract  = {Many agrammatic aphasics have a specific syntactic comprehension deficit involving processing syntactic transformations. It has been proposed that this deficit is due to a dysfunction of Broca's area, an area that is thought to be critical for comprehension of complex transformed sentences. The goal of this study was to investigate the role of Broca's area in processing canonical and non-canonical sentences in healthy subjects. The sentences were presented auditorily and were controlled for task difficulty. Subjects were asked to judge the grammaticality of the sentences while their brain activity was monitored using event-related functional magnetic resonance imaging. Processing both kinds of sentences resulted in activation of language-related brain regions. Comparison of non-canonical and canonical sentences showed greater activation in bilateral temporal regions; a greater activation of Broca's area in processing antecedent-gap relations was not found. Moreover, the posterior part of Broca's area was conjointly activated by both sentence conditions. Broca's area is thus involved in general syntactic processing as required by grammaticality judgments and does not seem to have a specific role in processing syntactic transformations.

  title     = {Influence of bodily harm on neural correlates of semantic and moral decision-making},
  issn      = {1053-8119},
  year      = {2005},
  abstract  = {Moral decision-making is central to everyday social life because the evaluation of the actions of another agent or our own actions made with respect to the norms and values guides our behavior in a community. There is previous evidence that the presence of bodily harm-even if irrelevant for a decision-may affect the decision-making, process. While recent neuroimaging studies found a common neural substrate of moral decision-making, the role of bodily harm has not been systematically studied so far. Here we used event-related functional magnetic resonance imaging (fMRI) to investigate how behavioral and neural correlates of semantic and moral decision-making processes are modulated by the presence of direct bodily harm or violence in the stimuli. Twelve participants made moral and semantic decisions about sentences describing actions of agents that either contained bodily harm or not and that could easily be judged as being good or bad or correct/incorrect, respectively. During moral and semantic decision-making, the presence of bodily harm resulted in faster response times (RT) and weaker activity in the temporal poles relative to trials devoid of bodily harm/violence, indicating a processing advantage and reduced processing depth for violence-related linguistic stimuli. Notably, there was no increase in activity in the amygdala and the posterior cingulate cortex (PCC) in response to trials containing bodily harm. These findings might be a correlate of limited generation of the semantic and emotional context in the anterior temporal poles during the evaluation of actions of another agent related to violence that is made with respect to the norms and values guiding our behavior in a community.

  abstract  = {The flexible learning of stimulus-reward associations when required by situational context is essential for everyday behavior. Older adults experience a progressive decline in several cognitive functions and show deficiencies in neuropsychological tasks requiring flexible adaptation to external feedback, which could be related to impairments in reward association learning. To study the effect of aging on stimulus-reward association learning 20 young and 20 older adults performed a probabilistic object reversal task (pORT) along with a battery of tests assessing executive functions and general intellectual abilities. The pORT requires learning and reversing associations between actions and their outcomes. Older participants collected fewer points, needed more trials to reach the learning criterion, and completed less blocks successfully compared to young adults. This difference remained statistically significant after correcting for the age effect of other tests assessing executive functions. This suggests that there is an age-related difference in reward association learning as measured using the pORT, which is not closely related to other executive functions with respect to the age effect. In human aging, structural alterations of reward detecting structures and functional changes of the dopaminergic as well as the serotonergic system might contribute to the deficit in reward association learning observed in this study.
