Quick thinking? It’s all down to timing

A pairing of presynaptic and postsynaptic activity in a population of hippocampal neurons can reduce the required number of synaptic plasticity evoking events. When spikes occur within ten milliseconds of each other, synapses strengthen for up to four hours.

Entorhinal cortical neurons and traces are shown and described in the caption.

Researchers Discover that the Sleeping Brain Behaves as if it’s Remembering Something

UCLA researchers have for the first time measured the activity of a brain region known to be involved in learning, memory and Alzheimer's disease during sleep. They discovered that the entorhinal cortex behaves as if it's remembering something, even under anesthesia, a finding that counters conventional theories about memory consolidation during sleep.

Sleep readies synapses for learning

Hippocampal neurons become longer and stronger following a period of sleep deprivation. The study supports the hypothesis that sleep may weaken synapses, which are strengthened from learning, allowing for learning to occur after waking.
