then it will synapse onto a second sensory neuron that crosses over to the
other side of the medulla and that axon will continue to ascend now on the
contralateral synapse on the thalamus will then project up to the primary
somatosensory cortex.
Somatosensory pathways- Anterolateral pathways: Pain and Temperature
