I just want to make sure my understanding of the following is right. Please correct me if I have made any mistakes.

If you have a lesion in the spinal cord in the following areas, you will have these associated symptoms:

Fasciculus Cuneatus: T5 and up, ipsilateral loss of proprioception, fine touch
Fasciculus Gracilis: T6 and below, ipsilateral loss of proprioception / fine touch

Lateral Corticospinal: Ipsilateral motor function loss
Anterior Corticospinal: Contralateral motor function loss (UMN symptoms, hyperreflexia, etc.)

Lateral Spinothalamic: Contralateral pain / temperature loss (UMN symptoms, hyperreflexia, etc.)
Anterior Spinothalamic: Contralateral crude touch / pressure loss

Spinocerebellar: Ipsilateral gait / ataxia symptoms

Ventral Horn: Ipsilateral lower motor neuron issues (hyporeflexia, etc.)
Dorsal Horn: Ipsilateral loss of sensation
