SCENE:
Monkey Interareal Measures

DESCRIPTION:
Interareal neuroanatomical measures of long-range projection strength and laminar specificity (Supplementary Fig. 1a,b), and a non-invasive neuroimaging-derived measure of structural dissimilarity (Fig. 1d) in monkey cortex. FLN: Fraction of labeled neurons. Target area i is injected with a retrograde tracer that labels neurons in many source areas; the FLN in source area j is then defined as the fraction of all labeled neurons terminating in area i that originated in source area j. Each row of the FLN matrix is therefore normalized to 1. Measurements which yielded no labeled neurons are colored in white. SLN: Fraction of supragranular layer neurons, defined as the fraction of neurons in a projection (to target area i from source area j) originating in supragranular layers. An SLN of 1 indicates that all labeled projection neurons were of supragranular origin, reflecting a pure feedforward connection; an SLN of 0 indicates that all projection neurons originated in deep infragranular layers, reflecting a pure feedback connection. Measurements which yielded no labeled neurons are colored in white.
