Fig. 2: Thalamocortical structural connections are consistently reconstructed in individual participants.

Exemplar thalamocortical connections included in the population-level tractography atlas (rows 1 and 4) are shown here, reconstructed in individual participants from PNC (rows 2 and 5) and HCPD (rows 3 and 6). Person-specific connections were robust and exhibited excellent reconstruction accuracy. Connection colors match those used in Fig. 1 and reflect the S–A axis rank of the thalamic connection’s cortical endpoint, ranging from the sensorimotor pole of the axis (yellow) to the association pole (blue). Each connection shown in the PNC and HCPD datasets is from a different participant; a random number generator was used to select which participant’s data to show. Data are shown from study participants that span the full age range in PNC (minimum age = 8.3 years, first quartile = 11.7 years, mean = 14.6 years, third quartile = 17.5 years, maximum age = 22.0 years) and in HCPD (minimum age = 8.9 years, first quartile = 11.0 years, mean = 14.9 years, third quartile = 18.6 years, maximum age = 21.8 years).
