I'm looking for the "earliest" specific site where the 3 following nerves' sensory signals "converge":
- Trigeminal nerve
- Median nerve
- Superficial peroneal nerve
By "earliest", I really mean the first location in the sensory pathway (to the brain) at which these 3 nerves' sensory signals converge. And by "converge", I mean "feed into each other". My understanding is that, with sensory nerves, all tactile reception roads lead to the somatosensory cortex, and so, I would imagine all the nerve signals converge/merge into one another at some point.
I would imagine the location I'm looking for is the brainstem, probably the pons, but I'm not a biologist and am looking for either correction or confirmation here. This uneducated guesstimate comes from two sources:
- Wikipedia - which states that the cranial nerves feed into the pons; and
- The fact that the median and peroneal nerves are spinal nerves, which ultimately feed into the medula, which then turns into the pons.
Am I right or way off track?
Please note: this is not homework!
