Measures of axo-somatic terminals on fusiform cells. (A) Relationship between the size of the axonal endings (n = 455) on fusiform cell somata and the number of active zones inside those endings. (B) Maximum length distribution of active zones measured in the terminals synapsing on somata. The maximum length refers to the distance spanned by the yellow line paralleling the active zone (white arrow) shown in the inset (n = 63). (C) Relationship between terminal volume and number of mitochondria. The data were taken from a random sample (n = 89) of axo-somatic terminals of three fusiform cells.
