Cortical Connectivity Data Sets

The following is a collection of commonly used large scale cortical connectivity data sets, compiled from tract-tracing studies. Hence nodes represent cortical areas, and links represent large cortico-cortical tracts.
  • macaque71.mat (BD network).
    Macaque cortical connectivity: 71 nodes, 746 links.
    Reference: Young (1993). Contributor: OS.
    Used in e.g. Sporns (2002).
    .
  • fve30.mat; fve32.mat (BD networks).
    Two version the macaque visual cortex.
    fve30.mat: 30 nodes, 311 links.
    fve32.mat: 32 nodes, 320 links.
    Reference: Felleman and van Essen (1991). Contributor: OS.
    Used in e.g. Sportns et al. (2000), Sporns and Kotter (2004).
    .
  • macaque47.mat (BD network).
    Large scale cortico-cortical connectivity matrix of the visual and sensorimotor areas in the macaque. 47 nodes; 505 links.
    Used in e.g. Honey et al. (2007). Contributor: RK.
    .
  • cat.mat (WD networks).
    Connection matrices of cat cortex.
    CIJall contains all cortical and thalamic areas: 95 nodes, 2126 links.
    CIJctx contains only 52 cortical areas: 52 nodes, 820 links.
    Reference: Scannell et al. (1999). Contributor: OS.
    Used in e.g. Sporns and Zwi (2004), Sporns and Kotter (2004).
Connection matrices and anatomical labels for areas of the human cerebral cortex. These data were generated by DSI (diffusion spectrum imaging) of 5 participants.  Participant A was scanned twice, hence the variable 'CM_all" contains a stack of 6 connection matrices (1 and 2 are from participant A, 3 is from participant B etc.).  Note that these connection matrices are weighted and symmetric (undirected).  Other variables are: 'anatlbls' - letter strings to indicate 66 anatomical subregions (see reference below), alphabetically arranged, with right hemisphere in positions 1-33; 'roilbls' - a vector of 1000 numbers one for each of the 1000 positions in the matrices (rois) where each number refers to the corresponding letter string in 'anatlbls'.  Note that positions 499 and 500 are zero and have no data entries, i.e. the total number of ROIs in the two hemispheres is 998.
When using this data, please refer to the original publication.  Plotting the matrices in 'CM_all' should produce a plot similar to Figure 3A in this publication.  Please note that the areas are not arranged alphabetically (as erroneously indicated in Figure 3A) but in the order in which they appear in 'roilbls'.
