Fig. 4From: Hippocampal injections of soluble amyloid-beta oligomers alter electroencephalographic activity during wake and slow-wave sleep in ratsTime course of SWA, theta, and alpha activity during SWS for BL and INJ days in Aβscr- and Aβo-injected rats. A The 24-h variations at the frontal electrode of SWA (0.5–5 Hz), theta (5–9 Hz), and alpha (9–12 Hz) activity in the Aβscr group (n = 9). B The 24-h variations at the frontal electrode in the same frequency bands in Aβo-injected rats (n = 6)Back to article page
