Theoretical models of working memory and episodic memory

The classical view is that working memory is mediated by persistent firing of selective groups of neurons. Recently, Misha Tsodyks proposed that working memory could be carried by selective short-term synaptic facilitation in neocortical connections, particularly, in the prefrontal cortex. The synaptic mechanism is more robust than persistent firing but requires a control system that would extract the information from synaptic into spiking form when it must be processed. In collaboration with experimental labs studying memory in humans and monkeys, Tsodyks is studying the implications of this theory for working memory capacity and recall of information from episodic memory.
