Distance Dependence of Electrical and Chemical Connection Probability

(A) Probability of electrical and chemical connections versus intersomatic distance in xy (sagittal plane) between recorded pairs.

(B) Probability of electrical and chemical connections versus intersomatic distance in z (transverse axis) between recorded pairs. Error bars indicate SD based on bootstrap analysis.

(C) MLI filled with biocytin and imaged using confocal microscopy after streptavidin-conjugated Alexa 488 histochemistry (left; blue, DAPI), and its reconstructed morphology (right).

(D) Superposition of 12 reconstructed MLI morphologies in xy view (left) and yz view (right). Bottom right, normalized density profile along the z axis. Dendrites (green) are more strongly confined to the sagittal plane than axons (black).
