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...

Recent research has suggested that an episodic specificity induction-brief training in recollecting the details of a past experience-enhances divergent creative thinking on the alternate uses task (AUT) in young adults, without affecting performance on tasks thought to involve little divergent thinking; however, the generalizability of these results to other populations and tasks is unknown. In...

Episodic memory endows autonomous agents with useful cognitive capabilities. However, for long-lived agents, there are numerous unexplored computational challenges in supporting useful episodic-memory functions while maintaining real-time reactivity. This paper presents and summarizes the evaluation of an algorithmic variant to the task-independent episodic memory of Soar that expands the class...

Numerous functional imaging studies have shown that retrieval from semantic and episodic memory is subserved by distinct neural networks. However, these results were essentially obtained with verbal and visuospatial material. The aim of this work was to determine the neural substrates underlying the semantic and episodic components of music using familiar and nonfamiliar melodic tunes. To study...

Previous neuropsychological and neuroimaging results have implicated the prefrontal cortex in memory retrieval, although its precise role is unclear. In the present study, we examined patterns of brain electrical activity during retrieval of episodic and semantic memories. In the episodic retrieval task, participants retrieved autobiographical memories in response to event cues. In the semantic...

The aim of this review is to summarize research on the emerging role of episodic memories in the context of anxiety disorders (AD). The available literature on explicit, autobiographical, and episodic memory function in AD including neuroimaging studies is critically discussed. We describe the methodological diversity of episodic memory research in AD and discuss the need for novel tests to mea...

Episodic memory, the recollection of past events in one's life, has often been considered a memory specific to humans. Recent work in a variety of species has challenged this view, and has raised important questions about the nature of episodic memory itself. We present a review of the types of task proposed as episodic-like in animals and consider that these tasks require animals to demonstrat...

Episodic memory provides a mechanism for accessing past experiences and has been relatively ignored in computational models of cognition. In this paper, we present a framework for describing the functional stages for computational models of episodic memory: encoding, storage, retrieval and use of the retrieved memories. We present two implementations of a computational model of episodic memory ...

Episodic memory refers to the recollection of a representation that binds together into a unique past experience "what" happened, "where" and "when". Sleep has been identified as a state that optimizes the consolidation of newly acquired memory. To determine if sleep is important for the consolidation of episodic-like memory, we tested rats on an episodic-like memory task requiring the binding ...
