The idea that memory is stored in the brain as physical alterations goes back at least as far as Plato, but further conceptualization of this idea had to wait until the 20th century when two guiding theories were presented: the “engram theory” of Richard Semon and Donald Hebb’s “...
2023年6月7日，山东大学陈哲宇教授研究团队在Science Advances杂志发表题为Altered fear engram encoding underlying conditioned versus unconditioned stimulus initiated memory updating的研究论文，探索了条件性刺激和非条件性刺激介导记忆擦除过程中记忆印迹细胞的编码机制，发现在记忆擦除过程中fear cell和extinction cell的...
engram- a postulated biochemical change (presumably in neural tissue) that represents a memory memory trace memory- something that is remembered; "search as he would, the memory was lost" Based on WordNet 3.0, Farlex clipart collection. © 2003-2012 Princeton University, Farlex Inc. ...
Tremendous strides have been made in our understanding of the neurobiological substrates of memory – the so-called memory “engram”. Here, we integrate recent progress in the engram field to illustrate how engram neurons transform across the “lifespan” of a memory — from initial memory encodi...

Once the engram is formed, anything that activates it will revive the original perception as a memory. Now where did I put those keys? Aligned with central theory is the belief that phantom limb phenomena, especially painful phantom limb, are a result of the cerebral structures forming a ...
researchers have attempted to identify the brain regions in which memory is formed and to follow its changes across time. The theory of systems consolidation of memory (SCM) suggests that changes in circuitry and brain networks are required for the maintenance of a memory with time. Various mecha...
Although researchers have had difficulty discovering the place within the brain where memory is stored, there are theories. This lesson looks at the theory of the engram and at the different research and researchers concerned with the topic. ...
Both theories ground themselves in the belief that the mind is emergent from the properties and processes of a material brain. Where these theories differ is in their description of what the neurobiological substrate of memory is and where it resides in the brain. The A/C theory of memory ...
The mechanism of memory remains one of the great unsolved problems of biology. Grappling with the question more than a hundred years ago, the German zoologist Richard Semon formulated the concept of the engram, lasting connections in the brain that result from simultaneous “excitations”, whose pr...
