Synapse type and postsynaptic targets of labeled postrhinal terminals in layers II/III of MEC: total numbers of anterogradely labeled synapses as assessed with EM in two animals^a

Target	Asymmetrical			Symmetrical		Undetermined		Total
	Spine: normal	Spine: perforated	Dendrite	Spine	Dendrite	Undetermined	Disagreement
n	164	96	15	1	4	126	2	408
%	40.196	23.529	3.676	0.245	0.980	30.882	0.490

^aSynapses are group as asymmetrical, symmetrical, and undetermined synapses and their respective postsynaptic targets, spines (normal and perforated), and dendrites. Undetermined synapses are those that show either inconsistent morphological features criteria or those for which the two assessors did not agree (disagreement).
