Fig. 1: Key predictions of LE/LI mechanism that selectively amplifies a characteristic wavelength of activity patterns.
From: Self-organization of modular activity in immature cortical networks
a The LE/LI mechanism: short-range interactions through a network connected with effective local excitation (red) and lateral inhibition (blue). b Networks with this connectivity scheme can selectively amplify activity at a characteristic wavelength, Λ. c Simplified one dimensional schematic, showing that uniform input drive produces spatially modular output with regularly spaced peaks and troughs close to the characteristic wavelength Λ of the network (gray bar). The spatial phase of the output patterns is variable, dependent on noise conditions (as indicated by dice). d When driven by a structured pattern with an input wavelength (λI) that is consistent with Λ, the output activity is biased towards the input pattern. e When driven by a pattern with an input wavelength that is slightly different than Λ (smaller in this example), the resulting wavelength of the output activity (λO) is intermediate, sitting between λI and Λ.
