The tectospinal, vestibulospinal and reticulospinal descend ipsilaterally in the anterior column, but do not synapse across the anterior white commissure.

在前柱中，顶盖脊髓、前庭脊髓网状脊髓身体作同侧地下降，但不穿过及与前白连合建立突触。

EPSPs with short latencies were concluded to be monosynaptic.Most IPSPs were generated through polysynaptic paths, but monosynaptic IPSPs were also recorded in the tectum.

短潜时的EPSP能是通过单突触进行传导的，而大多数的IPSP是通过多突触方式进行息传递的。
