Interpretation of correlated neural variability from models of feed-forward and recurrent circuits
Fig 6
Dependence of noise distribution orientation on average response, in data.
A, B: Typical examples, 6 neural populations recorded in the same animal. Relative variances projected on mean and diagonal directions, versus cosine of angle between mean response and diagonal. Each marker corresponds to a different stimulus. Different markers/colors denote different populations. Squares to the left side indicate . Solid lines: linear fits. C: Slopes from linear fits as in A, B of σμ/σall vs. slope from σd/σall, for all measured populations. Circles correspond to slopes for positive, squares to negative cos(r,d). Colors in all panels indicate value of cN in populations.
