The anterior and lateral spinothalamic tracts pass from the posterior grey horn to the opposite thalamus. The two tracts merge in the brainstem to form the spinal lemniscus, enter the ventral posterior nucleus of the thalamus and project to the somatic sensory cortex.

Additional sensory pathways are concerned with non‐conscious proprioception, reflex arc excitability, balance between agonists and antagonists, trunk and head orientation, arousal & motor learning:

 Posterior spino‐cerebellar tract, cuneo‐cerebellar tract, anterior spino‐cerebellar tract, rostral spino‐cerebellar tract

 Spino‐tectal tract, spino‐olivary tract, spino‐reticular fibres.

We cannot recognise lesions of these pathways clinically – they are part of the wider framework of motor and sensory modulation.
