Figure 4From: Developmental trajectory of the endocannabinoid system in human dorsolateral prefrontal cortexHigh power brightfield photomicrographs of CB 1 R mRNA positive cells/nuclei in layers II (A – D) and V (E – H) of the human DLPFC. CB1R silver grains (black dots) appear on small interneuron-like cells (large arrowheads) and larger pyramidal neuron-like cells (small arrows). Scale bar = 10 μm.Back to article page
