Hi, from a neuroscientist/medical writer. This is not my main area, but
I've thought that the somatotopic organization was true for the
postcentral gyrus and sensory receptors in general, analogous to the
____topic representations in the primary motor cortex, visual areas,
etc. I never heard of the somatotopic organization being broken down
into the various sensory receptors, but it certainly may be true.
Perhaps someone with more expertise could elucidate? I'd appreciate a
reference for the next time I teach A&P, as I try to keep the course
Incidentally, who was/were responsible for leaving us with the term
"receptor" to refer to both a binding site (eg, an ACh receptor) and a
sensory structure (eg, a rod or cone)? One of my more minor pet peeves
with neuroscience :-)
