Locating the engram: Should we look for plastic synapses or information-storing molecules?

JJ Langille, CR Gallistel - Neurobiology of Learning and Memory, 2020 - Elsevier
Karl Lashley began the search for the engram nearly seventy years ago. In the time since,
much has been learned but divisions remain. In the contemporary neurobiology of learning …
