These data come primarily from published work or expert opinion. It is likely that some differences in connectivity among brain regions may be due to differing opinion of brain region boundaries in addition to species differences.

All data was fit from the source data to statements that have two connected regions, i.e., connection from and connection to with the region abbreviation first followed by the region full name. Thus, an afferent from hippocampus to cortex (in the source data) would be aligned to “connection from” cortex, “connection to” hippocampus. The connection strength was aligned from symbols and numbers into the following categories: heavy, moderate, weak, not detected, exists, and unknown. Publications are reported and links to PubMed have been added, where possible. All other information that was available and relevant from each source was concatenated into the notes column.

The specifics of the alignment below:

• For CoCoMac the projection strength was translated as follows:
  • when l2_nif_0000_00022_cocomac_connectivity.density = '0' then 'Not detected'
  • when l2_nif_0000_00022_cocomac_connectivity.density = '1' then 'Weak'
  • when l2_nif_0000_00022_cocomac_connectivity.density = '2' then 'Moderate'
  • when l2_nif_0000_00022_cocomac_connectivity.density = '3' then 'Heavy'
  • when l2_nif_0000_00022_cocomac_connectivity.density = 'X' then 'Exists'
• For BAMS database:
  • lower (case when a.PROJECTION_STRENGTH like 'strong' then 'Heavy'
  • when a.PROJECTION_STRENGTH like 'very strong' then 'Heavy'
  • when a.PROJECTION_STRENGTH like 'light/moderate' then 'Moderate'
  • when a.PROJECTION_STRENGTH like 'moderate' then 'Moderate'
  • when a.PROJECTION_STRENGTH like 'light' then 'Weak'
  • when a.PROJECTION_STRENGTH like 'very light' then 'Weak'
  • when a.PROJECTION_STRENGTH like 'moderate/strong' then 'Heavy'
  • when a.PROJECTION_STRENGTH like 'not present' then 'Not detected'
• For BrainMaps:
  • when l2_nif_0000_00093_brainmaps_connectivity.strength like '++++' then 'Heavy'
  • when l2_nif_0000_00093_brainmaps_connectivity.strength like '+++' then 'Moderate'
  • else 'Unknown' ke '+++' then 'Moderate'
  • else 'Unknown'
