Blocking it stumps memory-guided decision-making in rats — NIH-funded study
Bethesda, Maryland–(ENEWSPF)–May 7, 2012. Awake mental replay of past experiences is essential for making informed choices, suggests a study in rats. Without it, the animals’ memory-based decision-making faltered, say scientists funded by the National Institutes of Health. The researchers blocked learning from, and acting on, past experience by selectively suppressing replay — encoded as split-second bursts of neuronal activity in the memory hubs of rats…
