Extended Data Fig. 4: Collation of the LFP recording sites in the hippocampal formation.
From: Coupling of hippocampal theta and ripples with pontogeniculooccipital waves
The images display a total of 26 recording sessions made in 5 monkeys (A13, 3 sessions; E10, 1 session; F12, 3 sessions; I09, 1 session; K13, 18 sessions). The location of the recording sites was derived from high-resolution anatomical scans and transposed onto the corresponding location on drawing of coronal slices of the Saleem–Logothetis rhesus monkey brain atlas62,63 (adapted with permission). All recording sites were located inside the hippocampal formation, with 12 sessions made in CA1, 9 in both CA1 and CA2, and 5 in CA3 or CA4. Relevant abbreviations: CA1-4, Ammon’s Horn 1-4; DG, dentate gyrus. Optic Tract at +18 LGN starts (clear in MRI) = +10 session AP(mm) Possible HP regions.
