LDSf identified connectivity between V1 and V5 in during the attention to visual motion task.

LDSf V1 → V5	No motion	Motion	Motion + attention
AR(1)	−0.06 ± 0.09	−0.02 ± 0.10	0.07 ± 0.07
AR(0)	0.22 ± 0.03	0.47 ± 0.07	0.65 ± 0.05

Shown are the estimated connectivity parameters and 95% confidence intervals derived via bootstrap for region V1 to region V5 for three different task conditions. Connections labeled AR(1) are the lag one autoregressive parameters from the A^u matrices. Connections labeled AR(0) are the instantaneous connectivity (${\mathit{\text{Ã}}}_{\mathit{\text{0}}}$) relative to the sampling rate derived from the Q^u matrices via Equations eight and nine. Only the AR(0) connectivity is reliably different from 0.
