Scaling Properties of Dimensionality Reduction for Neural Populations and Network Models

Neural populations and network models.
(A) Neural activity was recorded using a Utah array implanted in V1 of macaque monkeys during presentation of an isoluminant gray screen. (B) Clustered network consisted of 4000 excitatory neurons grouped into 50 clusters of 80 neurons. Triangles represent excitatory neurons and circles represent inhibitory neurons. Clusters had high within-cluster connection probability relative to between-cluster connection probability. Connection probabilities between excitatory and inhibitory neurons indicated above corresponding arrow. (C) Non-clustered network consisted of 4000 excitatory neurons with homogeneous connection probabilities.
