Male and female MeApd neurons are contacted by equivalent numbers of symmetric synapses. A, Example of MeApd symmetric spine synapses. B, Example of an MeApd symmetric shaft synapse. C, Symmetric synapse-to-neuron ratio is equivalent between males and females. D, The overall density of symmetric synapses is the same between males and females, with no differences between males and females in either symmetric shaft or spine synapses. E, The total number of symmetric synapses was equivalent between males and females. Sh, Shaft synapse; Sp, spine synapse. Arrowheads indicate boundary of synaptic clefts.
