Posterior cingulate activation during moral dilemma in adolescents.

Neuroimaging research examining correlates of adolescent behavioral maturation has focused largely on issues related to higher cognitive development. Currently few studies have explored neural correlates of emotional reactivity in adolescent groups. In this study, we sought to examine the nature of posterior cingulate activation during situations of moral dilemma in normal adolescents. We focus...

Task-dependent posterior cingulate activation in mild cognitive impairment.

Neuroimaging research has demonstrated that the posterior cingulate cortex (PCC) is functionally compromised in individuals diagnosed with amnestic mild cognitive impairment (MCI), a major risk factor for the development of Alzheimer's disease (AD). In functional MRI studies with healthy participants, this same region is active during self-appraisal (requiring retrieval of semantic knowledge ab...

Reduced anterior cingulate activation in aggressive children and adolescents during affective stimulation: association with temperament traits.

OBJECTIVE The risk for conduct disorder (CD) is markedly increased in children with specific temperament dimensions. Here, we investigated whether adverse temperament factors might contribute to an impairment in neural mechanisms underlying the regulation of aggressive behaviour. METHOD Functional magnetic resonance imaging was performed in 13 male adolescents with CD aged 9 to 14 years and i...

Mining Posterior Cingulate

Introduction One of the goals in human brain mapping is to relate brain areas to psychological functions. Meta-analyses can confirm presumed links and further suggest new directions for hypothesis-testing research [1]. The mounting functional imaging literature calls for new innovative computer assisted meta-analysis schemes. Here we describe a semi-automated data mining method combining text a...

Posterior Cingulate Neurons Dynamically Signal Decisions to Disengage during Foraging.

Foraging for resources is a fundamental behavior balancing systematic search and strategic disengagement. The foraging behavior of primates is especially complex and requires long-term memory, value comparison, strategic planning, and decision-making. Here we provide evidence from two different foraging tasks that neurons in primate posterior cingulate cortex (PCC) signal decision salience duri...
