Is it an idea to make the tag sensory systems the leading tag and synonimize the senses tag with it? I can't vote to do this, as I created the sensory systems tag. The senses tag info is currently not created and a simple link to sensory systems solves it.
Even better imo, I can change the existing senses tags into sensory systems, thereby auto-deleting the senses tag.
Thing is, the senses are generally viewed at as vision, smell, taste, touch and hearing. Sensory systems also includes the vestibular system, propriocepsis, haptics at large, among others. It's more encompassing imo.
I have thrown it in here, as 'senses' is a more common and more colloquial term. Since I am not a native English speaker, other more English-language-proficient people may object and might prefer senses, or might prefer to keep them separate. Folks might find my proposal inappropriate for other reasons.
There has been an earlier proposal to synonimize perception and senses. I vote against this, as perception enters the CogSci domain, while sensory systems is as Bio as it can be. Both tags should definitely stay, but separate imo.
