Learning connections between unrelated items requires neurons and brain circuits representing these items to be active and interact during sleep — ScienceDaily

Relational memory is the ability to remember arbitrary or indirect associations between objects, people or events, such as names with faces, where you left your car keys and whether you turned off the stove after cooking but before you left the house.

Previous research has established that animal and human memory benefits from sufficient, quality sleep. In a new study, published May 25, 2022 in the Journal of Neuroscience, Maxim Bazhenov, PhD, professor of medicine at University of California San Diego School of Medicine, and Timothy Tadros, a graduate student in his lab, describe the underlying mechanisms that strengthen or create new relational memories during sleep.

The authors developed an artificial model of two regions of the brain: the thalamic (involved in earlier sensory processing) and the cortical (involved in memory, learning and decision-making). The model was capable of…
