In VGluT2-labeled tissue	9	10	9	9.33
Total number of unlabeled (DAB-negative) asymmetric synapses	23	32	46	33.67
In VGluT1-labeled tissue	11	22	27	20.00
In VGluT2-labeled tissue	12	10	19	13.67

For each neuron examined, several properties were analyzed over a number of sections in either VGluT1- or VGluT2-labeled tissue.
