Abstract
ABSTRACT In a clever experimental design, Tallman, Clark, and Smith (this issue) tested the changes in fMRI activation and functional connectivity in the hippocampus and cortex as a function of memory age. They found that activation changed according to a power function (both increasing and decreasing) in several cortical regions but not within the hippocampus or medial temporal lobe (MTL). Further, functional connectivity increased with memory age between cortical regions but decreased for the hippocampus. Taken together, these results offer strong support for the standard consolidation model. However, they leave open the question of what role the hippocampus plays in recognition memory performance.
期刊介绍：
Cognitive Neuroscience publishes high quality discussion papers and empirical papers on any topic in the field of cognitive neuroscience including perception, attention, memory, language, action, social cognition, and executive function. The journal covers findings based on a variety of techniques such as fMRI, ERPs, MEG, TMS, and focal lesion studies. Contributions that employ or discuss multiple techniques to shed light on the spatial-temporal brain mechanisms underlying a cognitive process are encouraged.
