Material-specific neural correlates of memory retrieval.
It is well established that the neural activity engaged during memory retrieval varies with the kinds of information that are recovered. Less well established is whether this activity reflects online recovery of information, or processes operating downstream of successful recovery. We used event-related potentials (ERPs) to adjudicate between these alternatives, emphasizing that an online recov...
متن کاملNeural correlates of memory retrieval and evaluation.
Results from recent neuroimaging studies have led to a controversy as to whether right or left prefrontal regions are relatively more important for episodic retrieval. To address this issue, we recorded event-related brain potentials during two recognition tests with identical stimuli but differing retrieval demands. In both tests, participants viewed a sequence of object drawings, half of whic...
متن کاملNeural correlates of semantic and episodic memory retrieval.
To investigate the functional neuroanatomy associated with retrieving semantic and episodic memories, we measured changes in regional cerebral blood flow (rCBF) with positron emission tomography (PET) while subjects generated single word responses to achromatic line drawings of objects. During separate scans, subjects either named each object, retrieved a commonly associated color of each objec...
متن کامل[Neural correlates of memory].
Memory can be divided into several types, although all of them involve three successive processes: encoding, storage, and retrieval. In terms of the duration of retention, neurologists classify memory into immediate, recent, and remote memories, whereas psychologists classify memory into short-term and long-term memories. In terms of the content, episodic, semantic, and procedural memories are ...
متن کاملNeural correlates of memory retrieval during recognition memory and cued recall.
Regional brain activity, measured by H215O PET, was investigated during recognition memory and word-stem cued recall of words in order to compare the neural correlates of two components of memory retrieval-effort and success-as a function of task. For each task there was a baseline and two retrieval conditions. In one retrieval condition (zero density), none of the test items corresponded to wo...
