Episodic memory stores autobiographical memories of personal experiences with spatial, temporal, and emotional context. It enables "mental time travel" into one's own past.
Episodic memory is a subsystem of long-term memory that stores personal experiences with their spatial and temporal context. It differs from semantic memory (factual knowledge) through its autobiographical character and the possibility of subjectively reliving experiences. The concept was introduced by Endel Tulving. People with aphantasia often have intact semantic memory but altered episodic memories that are experienced less vividly and emotionally. In SDAM, episodic memory is severely impaired. The hippocampus and Default Mode Network are central to episodic memories. Research shows that visual imagination and episodic memory are closely connected, as both access similar neural networks.
SDAM is a memory condition where episodic autobiographical memories are severely limited. Affected individuals cannot mentally return to past experiences, although factual knowledge is preserved.
Learn moreThe Default Mode Network (DMN) is a network of brain regions active during daydreaming, self-reflection, and mental time travel. It shows altered patterns in people with aphantasia.
Learn moreAphantasia is the inability to voluntarily create mental images. People with aphantasia cannot visualize faces, places, or objects in their mind's eye, although they can recognize and describe them. The term was coined by neurologist Adam Zeman in 2015.
