Figure 5. Functional clustering predicts dendritic nonlinearities and somatic orientation selectivity.

Figure 5

(a) Examples of branches with different circular dispersion of orientation-tuned synaptic inputs, scale bar 5 μm; (b) gray scale depiction of dendritic spine circular dispersion in two neurons; scale bar 50 μm; (c) branches with lower circular dispersion show greater trial-to-trial correlations among active, orientation-tuned spines; (d) cluster density (circular dispersion <15°) is significantly correlated with somatic orientation selectivity; (e) cluster density is significantly correlated with spine/soma input/output nonlinearity; (f) spines in clusters (circular dispersion <15°) are tuned significantly more similarly to the somatic preferred orientation than spines on heterogeneous branches (circular dispersion >30°)
