Classification of YFP-Identified Retinotectal Synapses in the Stage 45 Xenopus Tectal Neuropil 24 Hours After Treatment¹

	Axoaxonal (%)	Axodendritic (%)	On filopodia (%)	On spines (%)
Control (n = 104)	3.52 ± 1.85	40.36 ± 6.88	47.55 ± 6.7	8.55 ± 4.56
BDNF (n = 101)	1.76 ± 1.77	36.92 ± 5.47	31.50 ± 8.9	29.8 ± 4.63²

In total, 11 brains were analyzed for controls and nine for BDNF-treated tadpoles. The relative proportion of each synaptic profile type was determined for each tadpole brain. Data represent the average obtained for all tadpoles per individual treatment and are expressed as percentage of total; n = number of synaptic terminals analyzed.

P = 0.0048.
