Functional brain interactions that serve cognitive-affective processing during pain and placebo analgesia.

abstract：:In this study we used functional magnetic resonance imaging to investigate age-related changes in large-scale brain functional networks during memory encoding and recognition in 12 younger and 16 older adults. For each participant, functional brain networks were constructed by computing temporal correlation matrices o...
