Remembering the past and imagining the future
The neural mechanisms underlying spatial cognition are modelled, integrating neuronal, systems and behavioural data, and addressing the relationships between long-term memory, short-term memory and imagery, and between egocentric and allocentric and visual and idiothetic representations. Long-term spatial memory is modeled as attractor dynamics within medialtemporal allocentric representations,...
متن کاملImagining the Past; Remembering the Future
When writing a short Comment on two long Articles it is difficult to be both substantive and polite. The available space must be devoted largely to points of disagreement, not to the authors' many fine arguments and insights. I therefore urge the reader to remember that this commentary lacks balance. My admiration for the projects that Chris Edley and Cass Sunstein have begun-projects that cont...
متن کاملRemembering the past and imagining the future: Identifying and enhancing the contribution of episodic memory.
Recent studies have shown that imagining or simulating future events relies on many of the same cognitive and neural processes as remembering past events. According to the constructive episodic simulation hypothesis (Schacter and Addis, 2007), such overlap indicates that both remembered past and imagined future events rely heavily on episodic memory: future simulations are built on retrieved de...
متن کاملRemembering the past and imagining the future in the elderly.
Recent research has demonstrated commonalities between remembering past events and imagining future events. Behavioral studies have revealed that remembering the past and imagining the future depend on shared cognitive processes, whereas neuropsychological and neuroimaging studies have shown that many of the same brain regions are involved in both remembering the past and imagining the future. ...
متن کاملThe Pivotal Role of Semantic Memory in Remembering the Past and Imagining the Future
Episodic memory refers to a complex and multifaceted process which enables the retrieval of richly detailed evocative memories from the past. In contrast, semantic memory is conceptualized as the retrieval of general conceptual knowledge divested of a specific spatiotemporal context. The neural substrates of the episodic and semantic memory systems have been dissociated in healthy individuals d...
