Extended Data Fig. 3. Cross-correlations between bilaterally recorded claustrum LFPs over nine hours of sleep.

a, Cross-correlation between left and right claustra for four animals and nine hours of sleep each. The shaded area (animal IV) corresponds to the segment shown in Fig. 2e. b, Recording locations in the left and right claustra, for two representative examples. Left, schematic of recording configuration. Middle and right, transverse sections through the anterior telencephalon (dark-field image), highlighting the recording sites (red stippled line), as identified by electrolytic lesions and DiI dye applied to the back of the silicon probes.
