From the Discussion in the paper A subset of broadly responsive Type III taste cells contribute to the detection of bitter, sweet and umami stimuli [1]: > Our data suggest that BR cells are a subset of Type III cells that are capable of responding to multiple taste stimuli, except sodium chloride. Since the BR cells always responded to sour, 100% of these cells responded to multiple taste qualities and approximately 80% of these cells responded to either three or four modalities (Fig 3D). This is in contrast to Type II cells that are usually narrowly tuned to a single taste quality. It appears that broadly responsive (BR) cells make the taste response slightly more complicated than original thought. Salty seems to be the odd man out and conforms to the original model; I'm not sure which observation I find more intriguing.
