Variability in CGF Structure across Neurons

(A–C) PCA of CGFs in the cortex.

(A) The absolute variance (i.e., average squared Δ gain) captured by each of the first 32 PCs. (PC numbers are plotted logarithmically.)

(B) Filled symbols: fractional variance in the CGFs captured by the leading PCs, as a function of number of PCs considered. Open symbols: fractional sum of squares of the mean cortical CGF that projects into the space spanned by the leading PCs, demonstrating how well the variance is aligned with the mean.

(C) The three leading PCs in order from left to right.

(D–F) PCA of CGFs in the thalamus. Subpanels correspond to (A)–(C).
