From: Thalamic inflammation after brain trauma is associated with thalamo-cortical white matter damage
Correlation of thalamic microglial activation and white matter damage in relation to distance from thalamus. a Partial correlation of thalamic [11C]-PK11195 (PK) binding potentials (BP) and thalamo-cortical fractional anisotropy (FA), sampled with increasing distance from the thalamus in TBI patients. Distance of 0 mm reflects sampling from tracts involving the thalamus proper. R (red) and p values are shown, with a threshold of p = 0.05 (dotted line). b Plot of residuals after for thalamo-cortical FA (x-axis), sampled from a ring-shaped mask 2 mm from the outer border of the thalamus versus thalamic PK BP (y-axis). c Partial correlation of PK BP in cortical grey matter and thalamo-cortical FA, sampled and plotted as in a
