Dorsal Column Medial Lemniscus (DCML) Pathway:
The dorsal column medial lemniscus pathway (DCML), is the sensory pathway responsible for transmitting fine touch, vibration and conscious proprioceptive information from the body to the cerebral cortex; as well as tactile pressure, barognosis, graphesthesia, stereognosis, recognition of texture, kinesthesia and two-point discrimination.
Dorsal column lesions:
- Multiple sclerosis
- Tabes dorsalis (Tertiary syphilis)
- Vitamin B12 neuropathy (due to vitamin B12 deficiency)
- Vitamin E deficiency
- Friedreich’s ataxia (Trinucleotide repeat disorder)
