REM Sleep and Theta Rhythm in the Hippocampus

Caption

This is a power spectrogram showing the changes in the neural activity of the hippocampus during sleep. The power of each frequency is plotted on the vertical axis with colors ranging from blue (lower) to red (higher). Sleep stages such as awake, REM and non-REM sleep could be identified thanks to changes in neural activity. Theta rhythm with 5-8 Hz oscillatory activity is dominant during REM sleep.
