Figure 1From: Visualizing spike activity during neuronal network developmentDevelopment of an in vitro culture. A. Mapping of electrodes to angles. Larger numbers indicate electrodes with higher spike detection. B. Trails describing spontaneous (red and pink) and stimulated (green and blue) spike activity at 4 div; both axes represent arbitrary distance units. C. 13 div. D. 24 div.Back to article page
