  3. A schematic of a neuronal circuit has three different groups of neurons. Blue excitatory neurons are at the top and bottom of the graphic. At top, in a darker shade of blue, are the primary memory-encoding neurons and at the bottom are light blue secondary memory-encoding neurons that are recruited during sleep. In between the two groups of excitatory neurons, there is a cluster of inhibitory neurons shown in red with its tendrils connected to both blue sets of neurons.
