Extended Data Fig. 2: Detailed description of the collected data.

The collected data (total of over 100 h of recordings) comprised a total of 630 10-min Data-Acquisition-Epochs, grouped in 66 groups, recorded during 42 experimental sessions (note that one session corresponds to one recording day). Experimental sessions consisted of concurrent functional MRI and electrophysiology recordings of spontaneous activity in 2 structures (24 sessions for PBn-HC, 6 sessions for PBn-LGN, 4 sessions for HC-LGN; animals A13, F12, K13, CM029, and E10), one session with the three structures (PBn-HC-LGN; animal K13) and 7 additional sessions with 3 structures including the LGN, VCX and hippocampus (LGN-HC-VCX; animals I09 and A13). A collation of the LFP recording sites for the PBn (25 exemplary experimental sessions; animals K13, CM029 and F12) and HC (26 exemplary experimental sessions; animals A13, E10, F12, I09 and K13) is reported here and in Extended Data Fig. 3. Electrode locations were derived from high-resolution anatomical scans, overlaid onto the corresponding coronal slices of the Paxinos rhesus monkey brain atlas or the Saleem–Logothetis combined histology-MRI of the rhesus monkey brain atlas. The remaining experimental sessions shared similar electrode positions to the ones reported here and in Extended Data Fig. 3, in consensus with the anatomical scans and the electrical profiles of the recorded signals.
