Area density of GluN1-positive and -negative axon terminals forming asymmetric synapses with dendritic spines in the PL-PFC of adult mice exposed to adolescent vehicle or THC

Axon terminals	Vehicle (n)	THC (n)	% Change
GluN1 positive	183	234	↑ 27.9%
GluN1 negative	1052	1017	↓ 3.3%
Column total	1235	1251	↑ 1.2%
% GluN1 positive	14.80%	18.70%	↑ 3.9%

n = number of axospinous synapses seen in 7978 µm² from THC and 8179 µm² in vehicle recipient mice
