Spontaneously emerging neuronal assemblies. (A1–6) Topographies of six examples of spontaneous neuronal assemblies. The neurons belonging to each of the assemblies are labeled in yellow. Red asterisks: assembly centroids. (B) Example of the spontaneously emerging spatial organization where all the spontaneous assemblies whose centroids lay on the right tectum. Neurons belonging to assemblies with similar topographic centroids were similarly colored. The colors represent the average normalized rostro-caudal centroid position of their assemblies. (C) The same representation for the light-spot-induced responses. Note the resemblance between (B,C), showing a graded change in colors along the rostro-caudal axes. Scalebars: 50 μm (reproduced with permission from Romano et al., 2015).
