The ventral trigeminal tract (also ventral trigeminothalamic tract, anterior trigeminal tract, or anterior trigeminothalamic tract) is a second-order neuron axon somatosensory tract conveying sensory information about discriminative and crude touch, conscious proprioception, pain, and temperature from the head, face, and oral cavity. The VTA arises from the spinal trigeminal nucleus and terminates in the ventral posteromedial nucleus of thalamus.[1]
Trigeminal ganglion → first-order neurons → spinal trigeminal nucleus and ventromedial division of principal sensory nucleus of trigeminal nerve (synapse) → second-order neurons (partial decussation) → trigeminal lemniscus (in midbrain) → (mostly contralateral) ventral posteromedial nucleus of the thalamus (synapse) → third-order neurons → sensory cortex of postcentral gyrus (synapse)
