Ventral cord syndrome - upper motor neuron weakness and loss of pain and temperature sensation (spinothalamic tract), with preservation of proprioception and vibration sensation (dorsal column)Anterior compression of the spinal cord, or anterior spinal artery pathology
Dorsal cord syndrome - loss of proprioception and vibration sensation (dorsal column), with preservation of motor function (corticospinal tract) and pain and temperature sensation (spinothalamic tract)Posterior compression of the spinal cord, or posterior spinal artery pathology
Brown-Sequard syndrome - ipsilateral upper motor neuron weakness and loss of proprioception and vibration (dorsal column), with contralateral loss of pain and temperature sensation (spinothalamic tract)Hemitransection of the cord
