Reactivation of encoding-related brain activity during memory retrieval.
Neuronal models predict that retrieval of specific event information reactivates brain regions that were active during encoding of this information. Consistent with this prediction, this positron-emission tomography study showed that remembering that visual words had been paired with sounds at encoding activated some of the auditory brain regions that were engaged during encoding. After word-so...
متن کاملRegional brain activity during working memory tasks.
The first aim of our PET study was to replicate previous findings concerning the brain areas activated by a verbal working memory task. The second aim was to specify the neural basis of the central executive, using a task of working memory updating. Our data confirm that the lower left supramarginal gyrus and premotor area are the key regions subserving short-term verbal memory processes. They ...
متن کاملMutual Influence of Reward Anticipation and Emotion on Brain Activity during Memory Retrieval
Previous studies on the joint effect of reward motivation and emotion on memory retrieval have obtained inconsistent results. Furthermore, whether and how any such joint effect might vary over time remains unclear too. Accordingly, using the event-related potential (ERP) measurement of high temporal resolution, our study investigates the cognitive and brain mechanisms of monetary reward and emo...
متن کاملAge-related Differences in Brain Activity during True and False Memory Retrieval
Compared to young adults, older adults show not only a reduction in true memories but also an increase in false memories. We investigated the neural bases of these age effects using functional magnetic resonance imaging and a false memory task that resembles the Deese-Roediger-McDermott (DRM) paradigm. Young and older participants were scanned during a word recognition task that included studie...
متن کاملBrain activation during episodic memory retrieval: sex differences.
Behavioral studies have shown a tendency for women to outperform men on episodic memory tasks. Here, data from a series of positron emission tomography (PET) studies were analyzed to examine sex differences in brain activity associated with episodic memory retrieval (yes/no recognition). A total of 17 women and 17 men were included in the analyses. The strongest effect of the design was a retri...
