Nighttime sleep renormalizes net synaptic strength (homeostatic plasticity) and the inducibility of long-term potentiation (LTP)-like plasticity (associative plasticity) in the cortex. However, whether an afternoon nap is sufficient for this process remains to be characterized.
Methods
Twenty healthy adults participated in a repeated measures sleep laboratory study with an adaptation and two experimental sessions – nap and wake (1:15–2:15 pm).
