A note for Lesson no. 1, "You Have One Brain (Not Three)," in Seven and a Half Lessons About the Brain by Lisa Feldman Barrett.
Some context from page 18‌‌ is:

Your brain has four clusters of neurons [...] collectively called the primary somatosensory cortex. In a rat brain, however, the primary somatosensory cortex is just a single region that performs the same tasks.
