A single-trace dual-process model of episodic memory: a novel computational account of familiarity and recollection.

abstract：:Metabolic integrity of glial cells in field CA1 of the guinea pig hippocampus is critical to maintenance of synaptic transmission (Keyser and Pellmar [1994] Glia 10:237-243). To determine if this tight glial-neuronal coupling is equally important in other brain regions, we compared the effect of fluoroacetate (FAC), a...
