Terminals coming from thalamic reticular nucleus establish symmetrical synaptic contacts with these dendrites. Dendrites of the DLG interneurons also act as axons and establish symmetrical synapses on the dendrites of relay cells.

• 视网膜和视皮质来的轴突终末对DLG投射神经元和中间神经元的树突形成非对称性突触,丘脑网状核的轴突终末则对这两类神经元构成对称性突触,而中间神经元树突具有轴突样作用,对投射神经元树突形成对称性突触。
